After being kicked,the back of my left testes looks like a mass of strands tubes i can feel when i touch them while the back of my right testes feels smooth and doesnt feel like the back of the left.Also recently i notice prominently a vein across the side of my left testes,i am sure it is on the testes,it is lateral along the side of the testes,plz can you tell me whatz wrong,hope it wont affect my productivity in any way?Plz i need to know coz im worried. Besides,i got kicked when i was 13, and now i am 19, i also feel dull ache in my left abdominal cavity .Thanks. Also can the size of the genitals still increase after age 19,when does the growth stops?
