Im 40 yrs old, 5 11,210 lbs and no serious medical history. About a month ago i was dragging myself off the bed when i put all my weight down and injured my right testicle,it was swollen and quite painful for a week or so but the swelling went down and the pain has gone,but still after about a month i am left with a hard ish lump which feels like its on the side of my testicle.... Is this just fluid or hard blood left behing from the swelling or something i should really get checked by my doctor?
Hi and welcome to Chat Doctor. Thank you for your query. It sounds like varicose vein or epidermal cyst and usually isn't anything serious. Especially considering that it last for 3 years.  If I am right then treatment isn't needed. Just watch for any new signs such as pain, swellings or urinating difficulties. It can also be inguinal hernia if this is prominent when you cough or do exercise. You can do ultrasounds to verify the exact diagnosis but I don't think you should worry. Wish you good health. Regards
