Testicular Pain: Causes, When to Worry, and Treatment

Testicular pain is discomfort in one or both testicles that can come on suddenly or gradually. Common causes include injury, infection, and testicular torsion. Sudden, severe pain requires emergency care. Always see a doctor if you're unsure about your symptoms.

In plain words

Testicular pain is discomfort in one or both testicles that can start suddenly or slowly. It can be mild or very severe. Some causes are harmless, but others need quick medical care. Common causes include infections, injuries, or a twisted testicle called torsion. Torsion is a serious problem that needs emergency surgery. Pain with nausea or fever is especially worrisome. Mild pain that lasts more than a few days should also be checked by a doctor. Treatment depends on the cause and may include antibiotics, rest, or sometimes surgery.

What is Testicular Pain: Causes, When to Worry, and Treatment?

Symptoms

Early symptoms

Mild discomfort or aching: A dull ache or feeling of heaviness in one or both testicles that comes on gradually. The pain may come and go or be constant. (4)
Swelling or tenderness: The affected testicle may appear swollen, feel tender to touch, or be slightly red. This often happens with infections like epididymitis. (4)
Pain worsening with movement: Discomfort may increase when walking, running, or during physical activity. Some men notice it more after prolonged sitting. (4)
Referred pain from abdomen: Sometimes pain feels like it's in the testicle but actually comes from elsewhere, like kidney stones or hernias. The abdomen may ache too. (4)

Serious or emergency symptoms

Sudden, severe testicular pain: Extreme pain that starts suddenly without injury could signal testicular torsion (a twisted testicle). This is a medical emergency requiring surgery within hours to save the testicle. Seek emergency care immediately. (4)
Pain with nausea/vomiting: Severe testicular pain combined with nausea or vomiting often suggests torsion or another serious condition. Don't wait for symptoms to improve on their own. Go to the nearest emergency department. (4)
High fever or pus discharge: A high fever (over 101°F/38°C) or pus from the penis may indicate a serious infection like orchitis that needs prompt antibiotic treatment. See a doctor within 24 hours. (4)

Causes

Primary causes

Epididymitis (infection): An infection of the coiled tube (epididymis) at the back of the testicle causes gradual pain, swelling, and sometimes fever. Often due to UTIs or STIs. Treatable with antibiotics. (1) (2)
Testicular torsion: A medical emergency where the testicle twists, cutting off its blood supply. Causes sudden, extreme pain. Most common in teens but can happen at any age. Requires immediate surgery. (1) (2)
Injury or trauma: Direct blows to the groin during sports, accidents, or other impacts can cause immediate or delayed pain and swelling. Severe injuries may need evaluation. (1)
Kidney stones or hernias: Pain starting in the abdomen or back may radiate to the testicles. Kidney stone pain typically comes in waves. Hernias cause a bulge in the groin area. (1) (2)

Risk factors

Individual risk factors for testicular pain vary by medical history

Risk factors depend on the underlying cause. Discuss your personal risk with your doctor. (1) (2)

Diagnosis

Doctors start by asking about your symptoms and doing a gentle physical exam. They check for swelling, tenderness, and abnormal positions of the testicle. An ultrasound may be used to check blood flow for torsion or look for signs of infection. Urine tests can identify infections, and blood tests may check for inflammation. Your doctor may also examine your abdomen to check for referred pain causes.

Physical examination

To assess tenderness, swelling, and the position of the testicle. The doctor may check for signs of infection or hernia. (3)

Urinalysis

Checks for urinary tract infections that might cause epididymitis. Looks for white blood cells, bacteria, or other signs of infection in urine. (3)

Ultrasound imaging

A Doppler ultrasound shows blood flow to the testicle. Helps diagnose torsion, infections, tumors, or other structural issues. (3)

Treatment

Medication options

Antibiotics

Used to treat bacterial infections causing epididymitis or orchitis. The type depends on whether the infection is sexually transmitted or not. (4)

Pain relievers

Over-the-counter NSAIDs or acetaminophen can ease discomfort from mild cases. Don't use these as a substitute for seeing a doctor if pain is severe. (4)

Lifestyle and self-care

Scrotal support: Wearing supportive underwear or an athletic supporter can relieve discomfort by reducing movement and providing gentle pressure. (3)
Ice packs: Applying a wrapped ice pack for 15-20 minutes several times a day can reduce swelling and dull pain from injuries or inflammation. (3)
Limited activity: Avoid strenuous exercise, heavy lifting, or sexual activity until pain improves. Rest helps healing, especially after infections or injuries. (3)
Sitz baths: Soaking in warm (not hot) shallow baths may ease discomfort from infections or swelling. Dry the area thoroughly afterward. (3)

Always discuss dosing and treatment changes with your own prescriber.

When to see a doctor

Routine follow-up

Make an appointment if you have persistent mild testicular pain lasting more than a few days, even if it comes and goes. Also see your doctor for recurring discomfort. (1) (2)

Seek emergency care

Go straight to emergency care if you have sudden, severe testicular pain (± nausea/vomiting), which could be testicular torsion. Time is critical - treatment is needed within 6-12 hours. (1) (2)
Seek same-day medical attention if you notice testicular swelling with fever, pus discharge, or inability to urinate, as these suggest serious infection. (1) (2)

Frequently asked questions

What's the most serious cause of testicular pain?

Testicular torsion is the most urgent cause - it cuts off blood supply to the testicle. Without emergency surgery within 6-12 hours, the testicle may be lost. Always seek immediate care for sudden, severe pain. (1)

Can testicular pain go away on its own?

Mild pain from minor injuries or mild infections sometimes improves with rest and home care. But persistent or worsening pain needs medical evaluation. Never assume severe pain will resolve without treatment. (1)

Is testicular pain always an emergency?

No - mild discomfort may not be urgent but still deserves medical assessment. Sudden, severe pain always requires same-day emergency evaluation to rule out life-altering conditions like torsion. (1) (2)

Can sitting too long cause testicular pain?

Prolonged sitting may contribute to mild aching from pressure or slight swelling. But significant pain isn't normal and shouldn't be blamed solely on sitting. Discuss persistent symptoms with a doctor. (1)
