Answer
I really don't feel comfortable answering your question as my expertise is in total hip replacement.  My rule of thumb though, is that if something seems wrong with you body, see a doctor.  In your case, a good orthopedist would be the best bet since he or she can properly diagnose you.

Good Luck
