Ontheroadback--

It is good you are getting some forward progress.

I would seriously have you consider some magnesium supplementation.
I have a thread on it here, at the vitamin forum.

1) a simple way to feel better is to soak the feet in epsom salt baths.
In a foot bath you need about 2 ounces of epsom salts and soak at least a
1/2 hour or more if you can.
If you see some improvement with this, then

2) start some magnesium in the diet (see that thread), or take a good supplement like SlowMag (twice a day). This often stops crampy pain in its
tracks.

Also to consider is thiamine for PN. Doctors do not test for this, and you can
add that in very inexpensively now, with no side effects. At least 200mg a day up to 500mg a day in divided doses. Thiamine has a long history of being useful for PN, but with Neurontin and its aggressive salesmen, was totally forgotten by doctors. Thiamine can be really effective for some people!
Some people inherit errors of metabolism concerning thiamine...so if you are one you may not even know it!

Good luck!
