The Arthritis Sourcebook Creams, sprays, or rubs applied on the skin over a painful muscle or joint are called topical pain relievers or topical analgesics .

Salicylates are a family of drugs that reduce inflammation and pain.
They come from the bark of the willow tree and are the pain relieving substance found in aspirin. Small amounts relieve mild pain. Larger amounts may reduce both pain and inflammation. Salicylates decrease the ability of the nerve endings in the skin to sense pain. Irritants, another type of topical ingredient, stimulate nerve endings in the skin to cause feelings of cold, warmth, or itching, which avert attention from the actual pain.
