Get StartedSymptoms
By Mayo Clinic staffOrchitis symptoms usually develop suddenly. Orchitis symptoms may include:
- Testicular swelling on one or both sides
- Pain ranging from mild to severe
- Tenderness in one or both testicles, which may last for weeks
- Nausea
- Fever
- Discharge from penis
- Blood in the ejaculate
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 experience pain or swelling in your scrotum, especially if the pain comes on suddenly, see your doctor right away.
A number of conditions can cause testicular pain, and some of the conditions require immediate treatment. One such condition involves twisting of the spermatic cord (testicular torsion), which may cause pain similar to that caused by orchitis. Your doctor can perform tests to determine which condition is causing your pain.
