I've never heard of anyone with elevated B12. Usually the B12 is either normal or too low. Believe me when I say most doctors have no clue about the correct way to read B12. Could you post your B12 number.

I also have autoimmune neuropathy. I have SFSN from Sjogren's Syndrome and Rheumatoid Arthritis. I've had it since 2003 after I had bi-lateral knee replacements. I have never been offered IVIG. I am maintained on methotrexate and Humira. Methotrexate stopped my neuropathy. No... it didn't stop the pain but it seems to keep it under pretty good control. At least it isn't advancing rapidly. As long as I keep my sugar consumption down, take all my supplements and keep moving, I get along pretty well.

Yes, there are times that I am in more pain but I still have my hands.
I'm a jewelry designer and artist. My hands are important to me. Please read the stickies at the top of the page. You have a lot to learn. This forum is chock full of the smartest people I've encountered. Also, check out www.lizajane.org for diagnostic tools.

Good luck,
