You seem to be travelling down a similar path to the one I followed. I have had several tests over the years for MS. I was also told I had plantar fasciitis. Add to that, morton's neuroma, achilles tendonitis, bursitis, rotator cuff tendonitis, tennis elbow. I could not believe it. I am not saying I did not and probably still do have mechanical issues which caused those itises but with CRPS the pain just goes on and on. The usual treatments suc as physio and orthotics in my shoes did not take away the pain. In the end what helped me was mirror visual feedback. I now from time to time have a shoulder problem or a hip/back issues. I do the physio and I do mirror therapy.
I no longer have the great list of problems. I hope things get sorted for you soon.
