Jeff,

You're very welcome.

I'm glad you will be getting a ferritin. Don't let them talk you out of it. The other iron indicators can be smack down the middle of the "normal" range in some people while iron stores are way off.

The neuropathy thing is semantics. Abnormal function of peripheral nerves is neuropathy, and parasthesis is abnormal function. Most docs mean that it isn't diabetic, CMT, etc. If it is due to B12 deficiency, it is systemic neuropathy (stemming from peripheral nervous system or central nervous system) just the same.

There is research indicating that low iron can also contribute to abnormal sensation in the legs. It is unlikely that a male is low in iron, but not impossible. It will be interesting to see what your ferritin result is.

It's unusual for such immediate responses to B12 doses, but I have seen a few others report it. Sounds good.
