For minor cupping burns without blistering, apply local iodine for disinfection and keep the area dry. If there are small blisters, let the skin absorb them naturally, disinfect daily with iodine, and keep the blistered skin intact. If the blisters are larger, clean a needle to puncture them and release the fluid, then keep the area dry and disinfect daily with iodine. If the patient has diabetes, or if the burn is severe or covers a large area, seek treatment at a burn clinic.
