I want to throw some questions out there to anyone. I have Small Nerve Fiber with no known cause yet. It is non-length dependent. I will repeat what happened to me. I woke up two days after I retired from my job and I had pinpricks allover head to toe and in my eyes. After many tests I then had a skin biopsy and that was the diagnosis. I asked the neurologist how many of his patients started out like I did. He said none its rare. So I started getting this pressure in the lower back of my head or neck that comes and goes but I had it in the front of my neck once. That was the worst. I felt like I was being choked. With the pressure in my neck my blood pressure goes up. I saw a neurosurgeon and he looked at my MRI with and without contrast. He says that the severe stenosis that I have is on the sides of my neck and that is not causing the pressure. I also woke up with pain that went from my left hip all the way down my leg. I turned over to my right side and it didn't go away for awhile. I had one other weird thing happen. I noticed a sharp feeling near the beginning of my left under arm closer to my right breast. Well I went to get ready for bed and I put my pjs on and I dropped something on the floor. When I went down to pick it up I had very sharp pains going down the right side of my breast. I am thinking nerve pain. I just don't know. I will be checking with the Doctor on these two things and the pain down my leg. I don't know for sure that is sciatica. I am more concerned with the pressure in my neck and the pain on the right side of my breast. I would love to hear from anyone who has experienced any of those things. One thing I did ask about was to an ARNP in gastroenterology. I do have chronic silent reflux and chronic gastritis and I read that some people can experience pressure in the neck. She said that she does have patients with that but when I told her my blood pressure goes up with it she started talking about nerves in the neck. I know they are all over our bodies. The pressure is the thing that bothers me the most right now. I appreciate any comments.
