Swollen testicles or scrotum can be due to various reasons like an enlarged vein around the testicle, accumulation of fluid or a tumor. In case of tumor the testicles are firm when touched with no pain. As you feel pain in your testicles the possibility of tumor is less. The scrotum generally feels soft with pain in case of fluid accumulation or swollen vein. Besides these reasons swelling can be due to some injury, infection or hernia. It is a serious condition and needs instant medical attention unless your swelling is due to some hard blow or some insect bite or ill fitted clothes.

Causes of testicular swelling
Testicular masses, such as a hydrocele, spermatocele, or (rarely) testicular cancer are also causes of testicular swelling. A hydrocele (fluid collection around the testicle), spermatocele (cyst that forms in the epididymis), and testicular cancer can all be painless, but can cause pain when they become large enough to press on other structures in the groin.

Because testicular swelling can be caused by some potentially serious processes, it's important that anyone experiencing testicular swelling be evaluated by a physician to determine the cause. Swelling accompanied by sudden, severe testicle pain requires immediate medical care. You should seek immediate care if:
-- Your testicular swelling is accompanied by severe or sudden pain, nausea, or vomiting
-- You feel a lump in the scrotum
-- Your swelling is accompanied by fever
-- Your scrotum is tender to the touch, is red, or feels warm
-- You have been in recent contact with someone who has mumps (virus that can cause orchitis)
