I tried capsaicin once - just once - when one of the docs on my peripheral nerve team suggested it. He said up front that he wasn't sure how it would work and that if it did, it might take awhile.

Almost immediately upon putting it on, it made the usual fire feel lukewarm. It was absolutely horrific, and trying to rinse it, etc. didn't even come close to helping. I had to let it wear off.

I'd love to know if it actually works. Unfortunately, it's just not for me.
