Groin pain refers to discomfort in the area where the abdomen ends and the legs begin. This article focuses on groin pain in men. The terms "groin" and "testicle" are sometimes used interchangeably. But what causes pain in one area does not always cause pain in the other.

Pain - groin; Lower abdominal pain; Genital pain; Perineal pain

Common causes of groin pain include:

• Pulled muscle, tendon, or ligaments in the leg -- This problem often occurs in people who play sports such as hockey, soccer, and football. This condition is sometimes called "sports hernia" although the name is misleading since it is not an actual hernia. It may also involve pain in the testicles. Pain most often improves with rest and medicines.
• Hernia -- This problem occurs when there is a weak spot in the wall of the abdominal muscle that allows internal organs to press through. Surgery is needed to correct the weak spot.
• Disease or injury to the hip joint.

Less common causes include:

• Inflammation of the testicle or epididymitis and related structures
• Twisting of the spermatic cord that attaches to the testicle (testicular torsion)
• Tumor of the testicle
• Kidney stone
• Inflammation of the small or large intestine
• Skin infection
• Enlarged lymph glands
• Urinary tract infection
• Problem with the artery or vein in the groin (femoral artery or vein)

Home care depends on the cause. Follow your health care provider's recommendations.

Contact your provider if:

• You have ongoing groin pain for no reason.
• You have burning pain.
• You have pain with swelling of the scrotum.
• Pain affects only one testicle for more than 1 hour, especially if it started suddenly.
• You have noticed changes such as a testicular growth or change in skin color.
• There is blood in your urine.

Your provider will do an exam of the groin area and ask questions about your medical history and symptoms, such as:

• Have you had a recent injury?
• Has there been a change in your activity, especially a recent strain, heavy lifting, or similar activity?
• When did the groin pain start? Is it getting worse? Does it come and go?
• What other symptoms do you have?
• Have you been exposed to any sexually transmitted diseases?

Tests that may be performed include:

• Blood tests such as a complete blood count (CBC) or blood differential
• Ultrasound or other scan
• Urinalysis
