I read in another post some where I think on the nutrition boards, that they missed MS in one person due to only scanning the brain for lesions and did not do the spine, later turned out they had lasions on their spine which was missed due to no spine scan or something like that...... Don't wanna freak you out, just thought I would let you know in case you continue to have problems. I too, have been having numbness and tingling, pricking sensations and muscle weakness on my right side, though and will be having a MRI done only to brain in a week. I wish they would do the spine too and get it over with. Have you had any problems swallowing? I get this and it's really effecting me badly......... can't eat well or much die to almost choaking every time. Food just sort of sits in back of throat past tonsils and wont move.............
