Thanks for the info Lara. I supplemented iron earlier in the year and stopped when my levels improved. Ferritin was the main culprit. A friend suggested B12 injections and I’ve asked my doctor for these. I know my Vit D hasn’t been great so I’ll be checking that as well.

Welcome Selenius.

--as the B12 thread will indicate, you can get your B12 levels up more easily with daily sublingual dosing, which avoids the expense and inconvenience of injections; even those with absorption problems can dose with at least 1000mcg/day (1 mg) or more and build B12 stores through even small percentage passive absorption.

That level around 200 is much too low. It may not be the primary culprit for your neuropathy situation, but it is likely contributing to it (and none of us are exempt from being "co-morbid"--having multiple causes for our situations).

Welcome, selenius!

Sorry I can't offer anything very helpful about SFN but I think it's entirely possible that the heat from the recent sweat test may have caused your symptoms to get worse. Some of these neurological flareups do calm down but it often takes far more time than you think it should.

If you can wait it out a bit longer, you might be pleasantly surprised and find that you're feeling better. I hope so.

Thanks. My doctor told me it could be a few weeks before it (maybe) calms down. It shocked me that I went from occasional symptoms to full blown in one afternoon.

Thanks Glenn. I’ve kicked off the B12 dosing after getting my bloods done Monday. As you say, it may not be the cause, but it won’t hurt to get the levels up.

Please let us know how you are doing.
I personally wouldn't have the injections at the doctor but would go with the Methycobalamin B12 that we can get here in Australia OTC these days. It actually wasn't that long ago we couldn't buy it here and I was having to import it from the US at some expense but now it's available. You have a baseline test result now, so that in the future you can re-test.
