You can try oral B12... use methylcobalamin 5mg daily on an empty stomach for 3 months. If there are improvements, then the B12 was your problem all along, even with the injections.
The genetic flaw is called MTHFR mutation, and can be tested for.
It is pretty common and many people have it.
Also there are two other blood tests... MMA and homocysteine.
These actually show if the B12 is working in the body. If elevated then it is most likely your B12 treatment isn't working for you. Doctors who are not keeping up with B12 treatment follow the old saw of one injection/month...and this does not work for everyone.
You can buy Methylcobalamin inexpensively at iherb.com, swanson's, or Puritan's Pride. Not commonly in stores yet, you may find it at a big health food store, but it will most likely cost more $$ than online.

It is important...must be METHYLB12
Also come UTI treatments use drugs that can cause PN.
Macrobid (Macrodantin)
Cipro, Levaquin, Avelox or other fluoroquinolone.
Do you know what antibiotics you took and how many times? |
Thank you again for all the info. On my previous post I forrgot to add the name of the new drug the dr putt me on...Methotrexate aNd Folic acid. Back to UTI anibiotics used - Macorbid - reaction was hepatatic and Jaundice and while in hospital I had shooting pain in right side of my neck and temporarily lost hearing in right ear, Quinolones - hives and difficulty breathing, IV anibiotiics began because of reactions - gentamycin- balance and hearing loss, mirrrapenem, heartbeat irregularities, a host of others I reacted to that I am seeing an. Allergist for. A big question for me is the ski punch biopsy - is it not the GOLD standard to do three sites?? Then if I was positive on the thigh AND foot they would know it is non-length dependant sfn? Then it would make sense to try immune drugs. Like I've mentioned the burning started aand remains the worst on my upper body. I know I seem to keep going in circles, but after. 15 years I just finally want answers and I feel I am so close now.
