the body is remarkable in healing

I am not sure why you mentioned Post Traumatic Stress Syndrome. Your neurologist said it wasn’t neurological. Well, that is HIS opinion. He may be right or he may have no idea so he used that excuse. If I were in your shoes, I would find a Naturopath if there is one in your area. If you cannot find one let me know. I might be able to help. Sometimes you are simply overloading your body with some food. I recently wrote an email on how soy cheese messed up my eyes. Left eye got blurry and I felt spacey. I cannot imagine what would have occurred if I had continued eating the soy cheese. Dr. Oz recently said that soy beans are fine but soy products are suspect. There is No way a doctor would have figured that out. Some of these really scary symptoms can be resolved. Eating tomatoes gave me painful bursitis. Luckily I stopped and the pain was gone in a day or two and I could move my left arm. Took a month or so til it completely resolved itself. Since your GBS was back in 98, it might have nothing to do with that. Do you have PTSD?
