I've been having groin pains,feels like its inflammed,taking tylenol,its helping a little,I do go to the gym and i get on this particuler stretching machine that streches your leg in the chinese spits position and it was ok for a month or so then it felt like i lost my strengh and whenever i picked up something heavy i could feel it in my groin area,over time eventhough i stop doing the stretch, i still feel the pain.
