Rule out an inguinal hernia with a surgeon who repairs these on a regular basis. I had similar symptoms and was being treated for awhile by a very good PT who had helped me and many of my athletes in the past. I had a a slight hernia that was going undetected until it got worse. It can cause all sorts of pain in the area and send you on a wild goose chase in an area in the anatomy that is hard to troubleshoot.
