So is it possible that all of these symptoms could be the result of a pinched nerve? I am unsure of what env. factors could be causing this - I eat very healthy (especially for my age) and live in an area that is not near any kind of toxins/factories. Also i looked up MP and it doesnt sound quite like it fits because i have had tingling as high as my stomach area. Also isnt CMT ruled out by the EMG test? I feel like my symptoms most closely match MS or CIDP but it seems through the tests i have had that both are ruled out...what kind of causes are left that would not affect the EMG (glenntaj - what diseases affect unmyelinated fibers)? I forgot to mention that I have very high arches in my feet (not sure if it matters). mrsD what is a homocysteine test? (it sounds like a normal blood test to me). Thank you guys so much! I am working very hard to figure this out before mid august because then I go back to school in a different state which will make further testing almost impossible.
