Hi.... The testicles are very sensitive. Even a minor injury can cause pain. In some conditions, abdominal pain may occur before testicle pain..... Non-urgent causes of testicle pain, such as minor injuries and fluid collection, can often be treated with home care. The following steps may reduce discomfort and swelling: Provide support to the scrotum by wearing an athletic supporter....Apply ice to the scrotum....Take warm baths if there are signs of swelling....While lying down, place a rolled towel under your scrotum....Try pain relievers,....
