When I was 16 or 17 I used to ride horses alot, one day while riding a horse I jumped on the horse and crushed my left testicle. Worst pain I ever felt in my life, I went to sleep for four hours afterwards before going home and not telling my parents, it was very sore for a long time but now that I am 24 I am worried about the effects not having it checked out may have had. Even though it doesn't bother me really anymore, is there anything I should worry about? I haven't been to a doctor in over ten years.
