If you see a doc, be sure he's an athletics- minded orthopedist. Then you might want to see if you can convince him to write you a script for Physical Therapy - just for the second opinion.
I think the ortho I saw was just having a bad day. Despite being in his early 30's at the oldest, he was whining how "When you get older, you just can't do as much!" He was telling me how if he plays basketball for 2 hours, he's a "hurting pup", whearas he could do that daily when he was younger. & how he simply cannot run, even though he loves it. He gets shin splints no matter what he does, so he just can't run.
NOT that attitude you want for someone to help you get back to good health so that you can slam around some iron!
