I have needles and pins in my feet for a year now spreading to my hands. Ive seen neurologist, reumatoligist, etc. I've been told that I have 5 times the normal r.a. levels but dont have r.a.. I've had a dozen different blood test with no conclusive results. I smoke 3cigerattes a day, been trying to quit for years and I dont drink on a regular basis. Do you think a visit to the mayo clinic would help? My life is starting to suck and I'm only 52 and I'm tired.
