I have been having progressively extreme leg/arm numbness, lack of circulation, almost impossible to lie down, legs burn and go to sleep. Difficulty with joints (and pain), muscles "lock up" with the slightest movement. Dizziness and weakness upon walking. Had diabetes test, MRI of lower back, blood tests, heart tests, neurology test of legs. Results a little high on diabetes and neuropathy, but not extraordinary enough to diagnose as a problem. Back is definitely in bad shape due to car accidents, no real "operable" back problems. Chiropactor no help either. I take lipitor and ambien. Tried giving up the lipitor, symptoms did not disapper ( I don't want my cholesterol to rise again, so I resumed). Any ideas, can barely walk at this point and am too weak and dizzy for almost everything. Continuing to work, had to give up gym and walks around the block. Symptoms seem to be increasing. Absolutely cannot lie on back, muscles lock up. Is there help out there, PLEASE!! Thank you for your compassion.
