Question: can icy hot help headaches?
Answer: Icy Hot has menthol and menthol salicylate, so it cools the skin and also causes a warming sensation that relaxes the body. Basically, it distracts your brain from the pain. If I'd had any capsaicin (an ingredient in chili peppers, this warms the body and relieves pain, too), I would have put that on, as well.
