Symptoms

Orchitis signs and symptoms usually develop suddenly and can include:

• Swelling in one or both testicles
• Pain ranging from mild to severe
• Fever
• Nausea and vomiting
• General feeling of unwellness (malaise)

The terms "testicle pain" and "groin pain" are sometimes used interchangeably. But groin pain occurs in the fold of skin between the thigh and abdomen — not in the testicle. The causes of groin pain are different from the causes of testicle pain.

When to see a doctor

If you have pain or swelling in your scrotum, especially if the pain occurs suddenly, see your doctor right away.

A number of conditions can cause testicle pain, and some require immediate treatment. One such condition involves twisting of the spermatic cord (testicular torsion), which might cause pain similar to that caused by orchitis. Your doctor can perform tests to determine which condition is causing your pain.
