Re: Pain in right thigh (front)
Just muscle tightness was my first guess and then nerve or other blockage was my second, but, hernia's a great idea for a source of pain around the groin that appeared (potentially) from lifting weights.
I think of swelling and intolerable/severe testicle pain as defining characteristics of hernias, but there must be less severe forms too. Maybe this hernia just isn't very bad (yet). Does it move the source of pain to cough?
Doctors all say, DO NOT ignore your hernia because you are no longer experiencing pain. A hernia, once present, will not go away on its own and you may be prone to subsequent attacks or more serious complications. Over time all hernias get bigger, never smaller.
So it seems really important to have a doctor check this if it could be hernia. You might need a minor surgery to prevent this from becoming much more serious eventually.
