What does your orthopedist say?
My story is not so similar, except the doctor running around stuff... but I got my physical therapist and my orthopedist to say to the neurologist that it was not a physical issue so that I could get the EMG and all...
Having had Cushing's, I know the steroids mess you up bad.
The docs use anxiety as an excuse when they do not want to think and they do not come up with an idea in the two minutes now that you are alloted. Try to research another doctor using a supportive doctor. Good luck.
