What is a testicle lump?

A testicle lump can be a symptom of injury, inflammation or infection. A testicle lump can result from swelling of the tissues or a cyst within the testicle. Injury leading to swelling is a common cause of a testicle lump. If there is injury or inflammation, the lump may be accompanied by pain, swelling or fever. Testicular torsion may lead to a lump in the testicle, which is associated with lightheadedness, nausea with or without vomiting, and pain. Depending on the cause, a testicle lump may occur in one or both testicles, but more commonly occurs in one testicle at a time.
