Does this thing work for treating joint pain (topical use)?
To quote Wikipedia:
"A rubefacient is a substance for external application that produces redness of the skin e.g. by causing dilation of the capillaries and an increase in blood circulation.
They are believed to relieve pain by a counterirritant effect, and many act via transient receptor potential ion channels. There is limited and conflicting evidence as to the efficacy of rubefacients."
Would I be better off with topical NSAIDs?
