Trolamine salicylate
"I find it difficult to walk due to what one doctor said was

planta faciiatis. I am on my feet for 10 hours sometimes.

I find that only certain shoes help; but when walking barefoot I needed relief. My wife had Mobisyl which contains 10% Trolamine Salic. It worked like a charm. 

Now trying it on my shoulders which hurt as well and hope it helps."
