Apply capsaicin topically.
Capsaicin is the chemical in peppers that makes them hot and is responsible for that mouth burn.
Capsaicin can also be found in limited quantities in cinnamon.
The warming effect that topical capsaicin creams provide has been shown to help relieve pain symptoms in arthritis, sore muscles, and neuropathic pains.
Just be sure to wash hands thoroughly after applying and even then, keep your hands away from your eyes.
