My boyfriend has pain in his left testicle;however, he has no bumps at all. He has pain on and off. Usually has pain when he tries to get up, walk, or puts pressure on it. He started having pain about 4 days ago. Does anyone have any idea what could be happening? He visited his doctor but he said he doesn't think its anything serious. The doctor mentioned that it might have turned by itself and may be cutting off circulation or that it may be a bacteria circulation. Any answers? Please help.
