This medication is used to treat minor aches and pains of the muscles/joints (such as arthritis, backache, sprains). Capsaicin works by decreasing a certain natural substance in your body (substance P) that helps pass pain signals to the brain. Menthol works by causing the skin to feel cool and then warm. These feelings on the skin distract you from feeling the aches/pains deeper in your muscles and joints.
