I had a really bad back spasm from a possible lumbar disc a year ago. Then within a couple months my low back started to burn, then my feet, legs, and then hands, feet, and face. Well, then I was tested for everything(MS, peripherial neuropathy, and small fiber neuropathy). I was negative for it all. I then got a cervical and thoracic MRI. It turned out I have a mild spinal cord compression in the C5-C6 area. I also have arthritis throughout my back. I have seen two surgeons who say I need fusion on the C5-C6. The only thing that changes color on my body are my feet. They will turn red off and on due to gettibng too hot outside and hurt. I don't get any swelling anywhere. Does it sound like RSD? I am afraid to have surgery if it is. I take meds for my all over body pain and burning. Meds help a lot and make it tollerable. I just can't walk for long distances. I get cramps in my legs. I am not sure if this is caused by the spinal cord compreesion or RSD? Thanks a lot everyone.
