Noxzema--just rub it in like hand cream. Cobroxin--$20.00 per 2 oz. Neuragen--$63.00 per 0.5oz Follow instructions on bottles.
These have all worked for me in combination with my oral pain meds. I have constant pain and numbness in both hands, wrists, elbows , feet, ankels, knees and neck. I hope one or more of these will work for you.
