Hello, my husband is 39 yrs old & has been having pain and sensitivity in his groin & testicular area. He has bph but hasnt started his medication yet. He doesn't experience this pain all the time but enough to affect his normal activity. It hurts to sit & walk & touch. It seems to also come after a bowel movement but also occurs without one. It comes & goes.
Besides the GPH diagnosis, have the doctors checked for a hernia? I'm guessing the pain comes whenever he strains to lift, push, move, etc., including straining for a bowel movement. To reduce that kind of strain, your husband needs to have foods high in fibre; an over-the-counter stool softener could also help a bit.
