Make an appointment for a full health exam, and discuss this problem in the context of the rest of your life, including any recent changes before your testicle started to hurt.
Testicular cancer most commonly appears as a firm, painless swelling of one testicle. Cancerous lumps in the testis are generally not tender when they are touched. Testicular cancer is a relatively rare form of cancer, usually occurring in men between the ages of fifteen and twenty-five years, especially if they have an undescended testicle.
Other causes of swelling of the testis, which are harmless: hydrocele, a collection of fluid in the scrotum; epididymal cyst, a fluid-filled swelling of the epididymis (the structure behind the testis where sperm mature), which may also cause fever and discharge from the penis; and varicocele, varicose veins in the scrotum, which is described as feeling like "a bag of worms." Inflammation of the testis can also be related to bacterial infections.
Torsion of the testis occurs when a testicle rotates, and the spermatic cord becomes obstructed and the blood supply is cut off. This most commonly occurs around puberty and causes acute severe pain and swelling of the testis. A hernia is the protrusion of an organ or tissue through a weak area in the muscle or other tissue that normally constrains it. The term is usually applied to a protrusion of the intestine through a weak area in the abdominal wall. The first symptoms of a hernia usually include a bulge in the abdominal wall and abdominal discomfort.
If during sex you are engaging in S & M (sadism and masochism), with twisting, pulling, or squeezing of your testicles, this may be a cause of pain. Otherwise, average masturbatory or sexual techniques do not cause your testicles to swell. It may be simply coincidence that you had more sex than usual before your testicle swelled.
Men are encouraged to perform a monthly testicular self-exam to become familiar with their anatomy, and to note if any changes occur. Do a testicular self-exam during a shower, when the heat of the water relaxes the scrotum. Rotate each testicle between your thumb and forefinger, making sure you feel a round, firm surface. Look at the rest of your scrotum's contents for any changes. If you have questions about this, ask your health care provider.
