I have had an off and on numbness in my Right inguinal area for the past 3-4 weeks. Thought it was from Weight training. It s now most of the time with a slight heaviness feeling to go along with it. I did have a fall this AM walking the dogs, but this was here prior except the heaviness. Testicles have no pain on examination, no pain noted.
Due to excessive weights training you might have developed weakness in right inguinal region. In case of swelling and numbness you might have developed hernia. Consult a surgeon.
