OP: I have the tingling down my right shin mostly and this is side of body I had hip replacement.
For me, Topricin homeopathic lotion is my best friend for all this...I can't imagine not having my supply -- the comfort this Topricin brings me.

And my B12 levels have always come in high as I've been taking Methyl B12 for years.

There is so much good info here for the PN issues and I am one who does not count on doc's drugs for help. I use all supplements and am much much better off... The longer one lives, the more they learn.
