"Capsaicin cream works amazingly well for my sciatica. I apply on the side of my leg, foot, lower back, or wherever I have pain.

Also: use plastic gloves to apply. You are applying essence of hot peppers to your skin and if you transfer it to your eyes it will really burn. It stays on your skin, so after 8-12 hours I scrub the area down with a soapy washcloth.  It reheats if you sweat or take a bath.   Without scrubbing it will reactivate if your skin gets wet."
