Testicular pain is pain or discomfort that is felt in one or both testicles. The pain may originate from the testicle itself, or it may be the result of other conditions affecting the scrotum, groin or abdomen. Though there are numerous medical conditions that can cause testicular pain, it is important to understand that a few of them constitute medical emergencies that require immediate medical attention in order to prevent impairment or loss of testicular function. Testicular pain can be an acute (short-term) or chronic (long-term) condition. The testicular pain may be constant or intermittent.
