Hello, I would be really thankful if you could help. I have a problem of swelling of my left testicle. I am not having any other issue that come along with it like fever. And also the swelling is periodic. Some times it last for a day or two and then for 1 week I am fine and again it start. I am also in a pain when I do activities like dancing. It is really painful and my testes swell and are hard and painful. The vessels near the lower part of my stomach also aches when swollen. I remember once 10 year back I got my testes hit on the front part of cycle, is it reliable? Please help.
