I have never stopped my exercises because it just has never felt like it was good enough to quit. I went back to my surgeon and he took xrays and said everything was fine. I asked why I was having so much pain and stiffness and he basically said I may just be in that percentage of people that will just have pain. I'm not ok with that answer but not sure where to go from here. I called another Dr for a 2nd opinion and after seeing my xray his nurse called me and said he wasn't willing to do a second opinion. Are there things that can be wrong that wouldn't show on an xray?
