Why do my balls hurt is a question millions of men search for every year, and it is one you should never ignore or feel embarrassed to ask. Testicular pain — whether it is a sharp sudden ache, a dull persistent throb, or a heavy dragging sensation — always has a cause.
The testicles are housed in a scrotum that is rich with nerves, blood vessels, and sensitive tissue, which makes them vulnerable to injury, infection, and a range of medical conditions. Some causes are completely harmless and resolve on their own within an hour.
Others are medical emergencies that require treatment within minutes.
Before diving into causes, it helps to understand what is actually inside your scrotum. The testicles, also called testes, are the two oval-shaped glands that produce sperm and testosterone.
Behind each testicle sits the epididymis — a coiled tube that stores and transports sperm. Running from each epididymis is the vas deferens, which carries sperm upward during ejaculation.
The entire structure is supported by the spermatic cord, a bundle of nerves, blood vessels, and the vas deferens that connects the testicle to the rest of the body. Because this system is so densely packed with nerves, even minor disruptions can cause pain that feels severe.
Pain can originate directly in the testicle or be referred from the kidneys, lower back, abdomen, or groin. This is why diagnosing testicular pain sometimes requires looking well beyond the scrotum itself.
A direct hit, fall, sports injury, or accident is the most obvious cause of testicular pain. The scrotum has very little protective padding, making the testicles highly vulnerable to blunt force.
Mild trauma causes sharp immediate pain that usually fades within 30 to 60 minutes. If pain lasts longer than an hour after an injury, or if swelling and bruising appear, seek medical attention right away.
Severe trauma can cause internal bleeding (hematocele) or, in rare cases, testicular rupture — both of which require surgical treatment.
Treatment: Ice wrapped in a cloth applied for 15 to 20 minutes, rest, and over-the-counter pain relief for minor injuries. Go to an emergency room for severe or worsening pain after trauma.
Testicular torsion is a genuine medical emergency. It happens when the spermatic cord twists and cuts off blood supply to the testicle. Without blood flow, the testicle can suffer permanent damage within hours.
It most commonly affects young men between the ages of 10 and 20, but it can happen at any age. The pain comes on suddenly and is typically severe, often accompanied by nausea, vomiting, and swelling.
If surgery is performed within four hours of symptom onset, most testicles can be saved. After 24 hours, the chance of saving the testicle drops dramatically.
Treatment: This is an emergency. Go to an emergency room immediately. Do not wait to see if the pain passes on its own. Surgery to untwist the spermatic cord (testicular de-torsion) is the only treatment.
Epididymitis is inflammation of the epididymis, the coiled tube behind the testicle that stores and transports sperm. It is one of the most common causes of ongoing testicular pain in adult men.
In younger men, it is most often caused by sexually transmitted infections (STIs) like chlamydia or gonorrhea. In older men, it is more commonly linked to urinary tract infections (UTIs) or urine reflux into the sperm ducts.
Symptoms include pain that builds gradually, swelling, redness, warmth in the scrotum, and sometimes discharge or a burning sensation when urinating. If the infection spreads to the testicle itself, the condition is called epididymo-orchitis.
Treatment: Antibiotics are the primary treatment. Rest, scrotal support (a jockstrap or supportive underwear), and over-the-counter pain relievers help manage symptoms. Most cases resolve within one to two weeks with proper treatment.
Orchitis is direct inflammation or infection of the testicle itself. It can be caused by bacterial or viral infection. The mumps virus is one of the most well-known viral causes, though vaccination has made this less common.
Bacterial orchitis usually develops as a complication of untreated epididymitis. STIs including chlamydia and gonorrhea can also cause orchitis.
Symptoms include significant swelling, pain in one or both testicles, fever, and general illness. In severe cases, the pain can rival that of testicular torsion.
Treatment: Bacterial orchitis is treated with antibiotics. Viral orchitis is managed with rest, ice, scrotal support, and anti-inflammatory medications. Seek medical attention promptly to confirm the cause and get the right treatment.
A varicocele is an enlargement of the veins within the scrotum, similar to varicose veins in the legs. It is present in about 15 percent of all men and is far more common on the left side due to differences in venous drainage anatomy.
Most varicoceles cause no symptoms at all. When they do cause pain, it is usually a dull ache or a feeling of heaviness, particularly after prolonged standing or physical activity. The pain often improves when lying down.
Varicoceles are also a leading cause of male infertility, so they are worth addressing even if symptoms are mild.
Treatment: Mild cases can be managed with scrotal support and over-the-counter pain relievers. If pain persists or fertility is affected, a surgical procedure called varicocelectomy may be recommended.
A hydrocele is a buildup of fluid around one or both testicles inside the scrotum. It creates visible swelling that may feel smooth and squishy to the touch. Hydroceles are common in newborns and also develop in adult men following infection or injury.
In adults, a large hydrocele can cause a dragging pressure or dull discomfort rather than sharp pain. The swelling itself can be alarming but is usually not dangerous.
Treatment: Small hydroceles that are not causing significant discomfort often resolve without treatment. Larger or persistent ones may require a minor surgical procedure to drain the fluid.
A spermatocele is a fluid-filled cyst that develops in the epididymis, often containing dead sperm cells. It feels like a smooth, separate lump near the top or behind the testicle.
Most spermatoceles are painless and are discovered incidentally during a self-exam or ultrasound. In some cases, especially larger ones, they can cause a sense of fullness or dull aching in the scrotum.
Treatment: No treatment is required for most spermatoceles. If they grow large or become uncomfortable, a urologist can remove them surgically. Do not confuse a spermatocele with a testicular lump — any new growth should be examined by a doctor.
An inguinal hernia happens when part of the intestine or abdominal tissue pushes through a weak spot in the abdominal wall into the groin or scrotum. The resulting bulge can cause pain that is felt in the testicles, particularly when coughing, lifting, or straining.
The pain from an inguinal hernia tends to be worse with physical activity and may be accompanied by a visible or palpable bulge in the groin.
Treatment: Surgical repair is usually required for inguinal hernias that cause persistent pain or grow in size. Do not attempt to push the bulge back manually as this can cause complications.
Kidney stones do not always stay in the kidney. As they travel down the ureter toward the bladder, they can cause referred pain that radiates into the groin, lower abdomen, and testicles.
The pain from kidney stones is typically sharp, cramping, and comes in waves. It is often accompanied by blood in the urine, nausea, vomiting, and difficulty urinating.
Many men are surprised to find that what they thought was testicular pain was actually a kidney stone all along.
Treatment: Small stones often pass on their own with increased fluid intake and pain relief. Larger stones may require shock wave lithotripsy or surgical removal. A urologist or emergency physician can confirm the diagnosis with imaging.
Epididymal hypertension — more commonly known as blue balls — is the aching sensation that can occur after prolonged sexual arousal without orgasm. Blood rushes to the genitals during arousal, and when ejaculation does not occur, the drainage is slower.
The condition is not dangerous and resolves on its own within a few hours. It may feel uncomfortable but poses no health risk.
Treatment: The discomfort fades naturally as blood flow returns to normal. Orgasm can resolve the sensation faster. It requires no medical intervention.
Prostatitis is inflammation of the prostate gland and is a surprisingly common cause of referred testicular pain. The prostate and testicles are closely connected anatomically, and irritation in the prostate can trigger a dull ache that radiates into the scrotum and groin.
Prostatitis can be bacterial or non-bacterial. Bacterial prostatitis often comes with fever, urinary symptoms, and pelvic pain. Non-bacterial prostatitis causes similar discomfort without evidence of infection.
Treatment: Bacterial prostatitis is treated with antibiotics. Non-bacterial prostatitis may be managed with anti-inflammatory medications, pelvic floor exercises, and warm baths. A doctor must confirm the diagnosis.
Chronic orchialgia is defined as three or more months of intermittent or constant testicular pain that significantly affects quality of life. It accounts for roughly 2.5 to 5 percent of all urology consultations in the United States.
The underlying cause is often difficult to pinpoint. Nerve damage, pelvic floor dysfunction, post-vasectomy pain, prior infection, or psychological stress can all contribute. When no clear cause is found, it is called idiopathic chronic orchialgia.
It most commonly affects men in their mid to late 30s. The impact on daily life, work, and relationships can be significant.
Treatment: Conservative approaches include anti-inflammatory medications, scrotal support, nerve blocks, and physical therapy focused on pelvic floor rehabilitation. More invasive options include microsurgical denervation of the spermatic cord or, in extreme cases, surgical removal of the epididymis.
Testicular cancer is almost always painless in its early stages. However, as a tumor grows rapidly, it can cause a dull ache, a heavy feeling, or a sense of pressure in the lower abdomen and scrotum.
It is one of the most common cancers in men aged 15 to 35, but it also has one of the highest cure rates of any cancer when caught early. Any new lump, hardness, or change in the texture or size of a testicle should be examined by a doctor immediately — whether or not there is pain.
Treatment: Depends on the stage and type. Options include surgical removal of the affected testicle (orchiectomy), radiation therapy, and chemotherapy. Early-stage testicular cancer has a survival rate exceeding 95 percent.
Some men experience ongoing testicular pain after a vasectomy. The vas deferens is sealed during the procedure, and in some cases this leads to pressure buildup, nerve irritation, or inflammation in the epididymis.
Post-vasectomy pain syndrome affects an estimated 1 to 2 percent of men who undergo the procedure. The pain can range from mild intermittent discomfort to severe chronic aching.
Treatment: Anti-inflammatory medications and scrotal support help mild cases. Reversal of the vasectomy (vasovasostomy) is an option for persistent severe cases. A urologist can assess the best approach.
Diabetes that is poorly controlled can cause nerve damage throughout the body, including in the testicles. This is because high blood glucose levels damage peripheral nerves over time, producing a burning, aching, or shooting pain that has no visible external cause.
Men with longstanding or uncontrolled diabetes who experience unexplained testicular pain should consider diabetic neuropathy as a possible contributor.
Treatment: Better blood sugar control is the foundation. A doctor may also prescribe nerve pain medications. This is a systemic issue that requires ongoing medical management.

Certain symptoms alongside testicular pain should prompt an immediate visit to an emergency room without delay. Do not try to manage these at home.
Seek emergency care right away if you have:
These signs point most strongly to testicular torsion, which can lead to permanent loss of the testicle if surgery is delayed.
Not every case of testicular pain is an emergency, but many still require a medical evaluation sooner rather than later.
Schedule a doctor or urologist appointment if:
Any lump on a testicle — painful or not — must always be evaluated. Testicular cancer has a very high cure rate when found early and a much lower one when found late.
A monthly self-exam is the simplest and most effective way to detect problems early. It takes less than two minutes and can be lifesaving.
The best time to perform a self-exam is after a warm shower or bath when the scrotal muscles are relaxed. Stand in front of a mirror and look for any swelling on the skin of the scrotum.
Gently hold one testicle between your thumb and fingers. Roll it gently between your thumb and forefingers, feeling for any hard lumps, changes in size, or areas that feel different from normal. Repeat on the other side.
The epididymis at the back of each testicle is naturally soft and rope-like — do not confuse it with an abnormal lump. If you feel anything that concerns you, see a doctor. Early detection is what makes testicular cancer so treatable.
For mild, non-emergency testicular pain, several at-home strategies can provide meaningful relief while you recover or wait for a medical appointment.
Wrap ice cubes or a cold pack in a clean cloth or towel. Apply it gently to the scrotum for 15 to 20 minutes at a time. Repeat every one to two hours as needed.
Never apply ice directly to the skin. Direct contact can cause frostbite and worsen tissue damage rather than helping it.
Wearing a jockstrap or snug supportive underwear lifts the scrotum and reduces strain on the testicles and spermatic cord. This is particularly effective for varicocele, epididymitis, orchitis, and general scrotal heaviness.
Avoid loose-fitting underwear or going without support when pain is present. Simple positional support makes a significant difference in how much discomfort you feel day to day.
A warm sitz bath for 15 to 20 minutes relaxes the scrotal muscles and improves blood circulation in the area. This is most helpful for dull, cramping pain or discomfort from minor strains and muscle tension.
Alternate between ice therapy and warm baths depending on the type and source of your pain. Ice is better for swelling and acute injury. Warmth is better for muscle tension and chronic aching.
Ibuprofen (Advil, Motrin) and acetaminophen (Tylenol) are both effective at managing mild testicular pain. Ibuprofen has the added benefit of reducing inflammation, making it particularly useful for epididymitis, orchitis, and varicocele-related aching.
Follow the dosage instructions on the label. Do not use OTC pain relief as a long-term solution without identifying and treating the underlying cause.
Avoid heavy lifting, strenuous exercise, and prolonged sitting or standing when experiencing testicular pain. Physical activity increases blood pressure in the groin and scrotum, which can worsen inflammation and discomfort.
Rest with your hips slightly elevated if possible. A rolled towel placed under the scrotum while lying down provides additional support and reduces the sensation of heaviness.
Knowing what to avoid during a flare of testicular pain can speed up your recovery significantly.
| Activity / Trigger | Why It Worsens Pain | What to Do Instead |
|---|---|---|
| Heavy lifting | Increases intra-abdominal pressure | Rest and modify activity |
| Prolonged sitting | Compresses scrotal nerves and vessels | Take breaks, use support |
| Tight restrictive clothing | Reduces circulation | Switch to supportive but non-restrictive underwear |
| Sexual activity during infection | Aggravates inflammation | Wait until treated |
| Hot baths for acute swelling | Increases blood flow to inflamed area | Use ice instead early on |
| Ignoring UTI symptoms | Can progress to epididymitis | Treat infections early |
The side of the pain can sometimes offer a clue about the cause. This is not a diagnostic tool on its own, but it can help inform the conversation with your doctor.
Left testicle pain is more commonly associated with varicocele, since the left testicular vein drains at a sharper angle and is more prone to valve dysfunction. Testicular torsion also slightly favors the left side for anatomical reasons.
Right testicle pain may indicate an inguinal hernia on the right side, kidney stones in the right ureter, or a spermatocele.
Both testicles hurting at the same time is more typical of orchitis, epididymitis that has spread bilaterally, or referred pain from prostatitis or kidney issues.
Pain deep in the groin or lower abdomen that seems to radiate into the testicles is a classic sign of referred pain — often from kidney stones, nerve compression in the lower back, or prostatitis.
Pain in the testicles after sex or ejaculation is a specific complaint that has its own set of causes. It is more common than most men realize and usually treatable.
A spermatocele can swell or become irritated by the muscular contractions during ejaculation. Epididymitis causes ongoing inflammation that is easily aggravated by sexual activity.
Prostatitis is another frequent culprit. The prostate and testicles share nerve pathways, so prostate inflammation can produce pain that is felt in the scrotum during or after sex.
If pain after ejaculation is consistent or worsening, see a urologist. Do not self-diagnose or attempt to manage this long-term without professional guidance.
The treatment your doctor recommends depends entirely on the underlying cause. Here is a summary of the main medical options.
Antibiotics are used for epididymitis, orchitis, prostatitis, and STI-related scrotal infections. The specific antibiotic depends on the suspected organism. A full course must be completed even if symptoms improve early.
Anti-inflammatory medications including prescription-strength NSAIDs help manage pain and swelling from varicocele, epididymitis, and chronic orchialgia.
Surgical options include testicular de-torsion (emergency), varicocelectomy, hydrocelectomy, spermatocelectomy, inguinal hernia repair, and microsurgical denervation of the spermatic cord for chronic orchialgia.
Spermatic cord nerve block — an injection of local anesthetic into the spermatic cord — is used both as a diagnostic tool and as a treatment for chronic orchialgia. If the injection relieves pain, it confirms the spermatic cord as the pain source and guides further treatment.
Antiviral medications are used for orchitis caused by viral infections when appropriate.
Physical therapy targeting the pelvic floor has shown strong results for men with chronic testicular pain linked to pelvic floor muscle tension or dysfunction.
Not all causes of testicular pain are preventable, but many risk factors can be reduced with consistent healthy habits.
Testicular pain without an obvious cause can come from varicocele, chronic orchialgia, referred pain from the lower back or kidneys, or early prostatitis. A urologist can help identify the source.
No. Many causes like minor trauma, blue balls, and small hydroceles are harmless and resolve quickly. However, sudden severe pain always needs immediate medical evaluation to rule out testicular torsion.
If pain from a minor injury lasts more than one hour, or if any testicular pain lasts more than a few days, see a doctor. Do not wait if pain is sudden, severe, or accompanied by swelling and nausea.
Yes. Prolonged sitting compresses the scrotal nerves and blood vessels, causing pressure and dull aching. This is especially likely if there is an underlying condition like varicocele or nerve irritation.
Testicular torsion causes sudden, severe one-sided pain that may come with nausea, vomiting, and a testicle that sits higher or at an unusual angle. It is a medical emergency requiring surgery within hours.
Yes. Chlamydia and gonorrhea are common causes of epididymitis, which produces gradual scrotal pain, swelling, warmth, and sometimes urinary discharge. Treatment with antibiotics is required.
Testicular cancer is usually painless in early stages. As a tumor grows, it can cause a dull ache or feeling of heaviness. Any new lump must be checked by a doctor regardless of whether there is pain.
Applying an ice pack wrapped in cloth for 15 to 20 minutes, wearing a jockstrap for support, taking ibuprofen or acetaminophen, resting, and taking warm baths are the most effective home measures for mild pain.
Yes. Kidney stones travelling down the ureter can cause referred pain that radiates into the groin and testicles. The pain is typically sharp, cramping, and comes in waves, often with blood in the urine.
Go to the emergency room immediately if you have sudden severe pain, a high-riding or rotated testicle, nausea and vomiting, rapidly worsening swelling, or pain that does not improve within one hour after trauma.
Why do my balls hurt is a question that deserves a real answer and prompt attention, not embarrassment or delay.
Testicular pain covers a wide spectrum — from a brief ache after mild trauma that fades in an hour to a medical emergency like testicular torsion that requires surgery within four hours to save the testicle.
Most causes, including epididymitis, varicocele, kidney stones, and minor injuries, are very treatable with the right medical care and simple home remedies.
The key is knowing the difference between what can wait and what cannot. Sudden severe pain, a new lump, fever with swelling, or pain that lasts more than an hour after injury all need medical evaluation without delay.
Perform monthly self-exams, practice safe sex, protect yourself during sports, and never dismiss ongoing scrotal discomfort. Your reproductive health is a direct reflection of your overall wellbeing — take it seriously.
