I used the arthritis topical pain reliever (capzansin hp) on my boyfriends back and didnt realize it said dont use heat on back after applying, and did so... and now his back has been on fire for an hour now. is there. anything i can do?

Cool with cold pack: He could have a cool shower to remove what is on the skin and use cold towel by putting in ice water or folding ice in a towel to dab on the back. Do not rub.

Wash off: Capsaicin is a derivative from hot chili peppers that causes a sensation of heat that activates certain nerve cells. With regular use this heating effect reduces the amount of substance P, a chemical that acts as a pain messenger in the body. Heat applied to this area, can cause over sensitization of the pain receptors. Wash area thoroughly with cool water and soap. Try again later without heat.
