When you’re standing in the drugstore staring at a wall of pain creams, patches, and gels, how do you know what actually works? Hari and Dr. Priyanka break down topical pain relievers, from diclofenac and lidocaine to menthol, camphor, and capsaicin, including what they do and which kinds of pain they can help. Plus, they cover the risks of burns, heating pads, overuse, and why reading the “active ingredients” on the label matters.
