Amiodarone affects the thyroid too. Have any of your doctors,
tested your thyroid lately?

We have had a few people come here on Coumadin, who had significant PN pain. I've searched and searched this and always came up with "nothing" connecting to Coumadin. But I suspect it can be a culprit for PN for some people.

The Benzo drugs (like Xanax etc) do help with pain in the short run, but in the long run they tend to make PN worse, as they wear off. Klonopin is the one typically given because it lasts a long time in the body. It is really best to avoid them. They work like the antiseizure drugs, and do have some antiseizure potential, but are so habit forming! The body tends to circumvent them over time, so PN often gets worse and not better and you are left highly dependent on them, and getting off them can be a nightmare.
