Topical pain killers are sprayed or rubbed into the skin over pain areas surrounding muscles, bones or joints. Each type of product uses different ingredients and work differently. Here are the most common ingredients found in products available without a prescription.

Counterirritants: include menthol, methylsalicylate and camphor. These don't necessarily cure your pain, but instead create a burning or cooling sensation that distracts your mind from the pain.

Capsaicin: is the main ingredient for hot chili peppers and can be very effective for short-term pain relief. Typically used for joint pain and for diabetic nerve pain, capsaicin creams cause a warm tingling or burning sensation that can relief or distract you from pain.

Salicylates: uses the same ingredients found in Asprin but instead can be applied through the skin. Success rates vary with this method, but it can help with many types of joint pain depending on the person.
