certain anaesthetics drain vitamin b12 which could have neuropathic consequences. i have not personally had relapses yet so i could not say for sure, but i definitely had my initial dx attack after a painful crash snowboarding. i don't really think it was the pain itself, i think it was that the trauma aggravated pre-existing spinal cord injury resulting in what seems, 5 years later, to be permanent damage.
odd sx? no dx? check w/ dietitian

'but my results are normal'. typical panels don't test all
