I had THR in June 2014, I am 42 years old and have had a really successful time of it so far.  I did how ever, have sex with my husband last night which before has not been a problem, but I guess I must have stretched too far because I am having pain in my groin area at the joint.  What I am asking is if maybe I have strained the area and it will get better or if maybe I might have actually hurt the joint?  I'm a little scared because I have to get the other one this summer.  Hello!!!! Still young here!!! Lol. Anyone have any input please? I hope I haven't offended anyone.
