thank you for all this information. you are of great help to me. i just looked at my b-12 level and it says 85. what do you think is the cause of the problem? the low b-12 or the abnormal blood protein? also i am not diabetic. i dont know if i mentioned that in my earlier posts. as far as b-12 i am taking the WSN nerve support formula which contains a lot of b-12 so maybe that will help? let me know what you think. when they did the brain scan they found no signs of MS but i heard MS doesnt always show on scans and abnormal protein is common in MS patients. could it in fact be MS?
