If by your 'doctor', you mean a general physician, I strongly suggest you get actual professional medical advice. GP's, in my experience, know a little bit about several things, nothing about a lot of things, and a lot about nothing.
GP's are generally only good for telling you that yes, something is indeed wrong. Jesus, I know Doc, that is why I came here.
Seriously, find someone who specializes in skeletal/muscular problems and talk to them.

Yea it was a GP. He did order some xrays and said "It doesn't appear to be bone related." and that is why he advised to just exercise and get into shape. I didn't follow his advice on that so far. If I am able to get my body into shape and still have issues I'll certainly hit him up for a referral.
