Methods for pain relief after burns are as follows: First, rinse with running cool water until the pain subsides, then disinfect with iodine, which can also help relieve pain; Second, apply toothpaste or aloe vera on the surface of the burn to achieve anti-inflammatory, cooling, and pain-relieving effects; Third, medication treatment may involve taking pain relief pills orally, such as celecoxib, or intramuscular injections of ketorolac tromethamine or butorphanol tartrate for pain relief if necessary; Fourth, apply cold compresses. Before applying ice, wrap the burnt area with a sterile cloth to reduce the risk of frostbite and avoid worsening the condition; Fifth, consider localized blocking by injecting saline or alcohol around the painful area, which can serve a blocking function and help alleviate pain. (Note: Use medications under the guidance of a physician.)
