Pain in Testicle and Inner Thigh

What are potential causes of pain in one testicle that radiates down the leg?

There are several potential causes of testicular pain that extends to the thigh, some of which can develop suddenly with no obvious cause. Among the more common causes of testicle and thigh pain are:

Injury

Getting hit in the scrotum the pouch of skin that surrounds the testicles can trigger considerable pain in the testicles immediately. Testicular trauma may also cause pain to radiate up into the abdomen or down the leg.

Other symptoms may include:

• blood in the urine
• difficulty urinating
• fever
• swelling
• bruising

If the injury seems minor and the pain passes quickly, you may not need medical attention. But if pain persists for hours or there are noticeable symptoms, see a doctor as soon as you can. If any tissue within the scrotum has been badly injured, surgery may be needed to repair the damage. If not, rest and a cold pack may be all you need to do.

Pinched or compressed nerve

Problems in your spine may be responsible for pain in your testicle and leg. For example, a pinched nerve in the spinal column can cause pain in nearby muscles and organs. It can also cause weakness, numbness, and tingling.

A herniated disk can also cause pinching of the nerve root, and the pain may not be localized to the disk or nerve itself. Instead, the pain may extend downward to the pelvis, groin, or inner thigh. Typically, the pain will be on the same side of the body as the pinched or compressed nerve.

Sciatica

The sciatic nerve extends from the lower spine, into the pelvis, and into the top of the legs. When this nerve is irritated, it can cause pain, numbness, and weakness in your back, groin, and eventually legs.

Sciatica most commonly occurs because of a herniated disk or a bone spur on the spine, but it can also be degenerative disc issues or spinal stenosis.

Muscle strain

Muscle strains and tears are the consequence of overuse of muscles. This may be the result of an injury or trauma, or simply the result of using the muscle extensively without thoroughly warming it up.

A muscle strain in the pelvis or groin may cause pain in the testicle and upper thigh. It might also cause muscle spasms, muscle stiffness, and limited movement.

Inguinal hernia

A hernia that occurs in your abdomen, near your groin, is called an inguinal hernia. Inguinal hernias develop when fatty tissues push through the lower abdominal wall near the inguinal canal.

Symptoms of an inguinal hernia include:

• bulging in the groin area that may be painful to the touch
• pain when coughing, exercising, or bending over
• burning sensations
• a heavy or full sensation in the groin area
• swelling of the scrotum in men

Surgery is the most common treatment for inguinal hernias that cant be pushed back into the abdomen.

Intestinal issues

Intestinal issues such as constipation, diverticulitis, colitis, peritonitis, and even appendicitis can all cause referred testicular and lower extremity pain. Its important to see a doctor if you suspect you have one of these conditions.

• Constipation. This common digestive problem is defined as having hard, dry bowel movements or passing stool fewer than three times a week. Persistent abdominal pain and pain in the lower back are just some of the symptoms you may experience.
• Diverticulitis. This common disease occurs when pouches form along the digestive tract, usually in the colon. These pouches can become inflamed and infected. Symptoms include constant pain in your abdomen.
• Colitis. This inflammation of your colon (large intestine) causes discomfort and pain in your abdomen, which may be mild and reoccurring over time, or severe and appear suddenly.
• Peritonitis. This condition occurs when your peritoneum becomes inflamed. The peritoneum is the thin layer of tissue that covers the inside of your abdomen and some of the organs. The inflammation is typically caused by fungal or bacterial infection. It can cause tenderness and pain in your abdomen and lower extremities.
• Appendicitis. The appendix is a small pouch attached to your intestine. When your appendix becomes blocked, bacteria can build up inside it. This leads to inflammation and painful pressure in your abdomen, usually on your lower right side. An appendix can burst if left untreated, causing bacteria to enter into your abdominal cavity. This can be serious and sometimes fatal. See a doctor immediately if you suspect you have appendicitis.

Renal colic

Renal colic is a type of pain you feel when urinary stones block any part of your urinary tract, which includes your kidneys, ureters, bladder, and urethra.

Urinary stones develop when minerals like calcium and uric acid form into hard crystals. Small stones the size of a grain of sand may not cause any symptoms and may pass on their own. But larger stones can cause renal colic, especially if they cause an obstruction in the ureter or kidney.

Symptoms include intense pain along the side of your body between your ribs and hip, and in your lower abdomen. The pain may also radiate to the testicle and to the hip or leg as well.

See a doctor if you have symptoms of renal colic or urinary stones.

Does it matter which testicle is painful?

Its not uncommon for the right testicle to be a little larger than the left testicle. This difference doesnt indicate a problem unless there are symptoms, such as pain, swelling, redness, or difficulties urinating or ejaculating.

Theres little difference between the right and left testicles. If anything, the left testicle may be more vulnerable to conditions such as varioceles, an enlargement of the vein within the scrotum. But pain from sciatica, muscle strain, spinal problems, or injury can occur in either testicle.

How is pain in one testicle diagnosed?

If you see a doctor about testicle pain and inner thigh pain, youll be asked about other symptoms you might be experiencing. Your doctor will also get a medical history and perform a physical exam.

Possible tests you can expect include:

• blood tests to check for infection or other health problem
• urine test, which can also indicate the presence of an sexually transmitted infection (STI)
• an ultrasound of the testicles to look for injury or trauma to the muscles

If a herniated disc is suspected, your doctor may order a CT scan or an MRI. Either of these tests should show the bulging tissue. An X-ray wont show a herniated disk, but it can rule out other potential causes.

Takeaway

Pain in the testicle and inner thigh can be triggered by any number of acute or chronic conditions. Some problems, such as a strained muscle or pinched nerve, typically run their course and resolve on their own. Other conditions, such as a herniated disc, may require more extensive treatment.

Sudden or severe testicle pain or pain that is accompanied by symptoms like a fever or blood in urine may be a medical emergency. You should see a doctor immediately.

About 50 percent of people who see a doctor for scrotal pain dont have an easily identifiable condition. For this reason, diagnosis typically requires a physical exam and review of symptoms, blood and urine tests, and in some cases an ultrasound or other imaging test.
