Shawley -I am no doctor but I swear after my discussions with my doctor that you are exhibiting symptoms of mechanical problems too.
When you are preparing to see this specialist, I would recommend you give very specific examples of when I walk, I have this pain in this location or when I sit, I have this pain, or if I do a bicycle, I have this pain. Also tell him what you have to do, to survive to maintain a low level of pain. I think I have learned that you need to give them concrete facts.
Hope this helps and please know that I care.
