What Is the Best Topical Painkiller for Nerve Pain?

Over-the-counter topical painkillers that contain capsaicin, botanical oils and lidocaine are recommended by WebMD. Lidocaine and capsaicin are also available in prescription strength. Topical painkillers function as local anesthetics that numb the pain in areas where the medication is applied.

Capsaicin topical treatments are made from chili peppers and can cause a burning sensation when first applied, states WebMD. The treatment may take weeks to effectively reduce nerve pain, but the burning sensation also decreases over time. Lidocaine ointments, pads and ointments works to numb pain when applied, but the effect is temporary. Products that contain botanical oils, such as geranium oil, can also reduce nerve pain.
