Hi Leslie & welcome to this forum, a fasting glucose test doesn't test your systems reponse to a glucose challenge like the GT test does, in the beggining of my PN troubles, a doc said my fasting glucose was normal, no sign of diabetes whats so ever but later on when i had the GT test, it showed i was prediabetic & it was the cause of my troubles, i am glad your still going to have it just in case.
Iv'e also have never heard of Celebrex causing PN, actually i was giving 6 celebrex per day in the early undiagnosed days of my pn and they helped a lot.
I wish you my best in finding the culprit.

Thanks Brian, for the info. I didn't think that celebrex was the casue of my PN but was just wondering. I did find a case study that indicated that 1% of those in the test group did develop PN so who knows. How is your PN doing since you found out the cause? Is it getting better?

Hi Leslie, yep, who knows... i read some were that the medication [ Endep ] that is very commonly used for neuropathy patients could also cause neuropathy, i used it for 5 years and it didn't harm my nerves at all... in answer to your question, i am doing real good my neuropathy is 99 % gone these days, i wrote my story up in the " Neuropathy does improve " section, up top on the front page.
With the serum b12 test, the Japanese pn experts say a score of anything below 500 is suspicious of b12 defiency.
best of luck anyway
