Thanks everyone for their thoughts. I had carboplatinum and taxol.

It got much better in the first six months, a little better in the first year, and has been the same since then, except lately I have felt the more burning, new jolts and zaps and the numbness spread to new areas.

Not sure if this is a temporary thing due to recent feet activity and so I became curious whether I should expect my feet to deteriorate as I age.

I have always learned way more from this forum than any doctor.
