I have been trying lidorderm patches but have not felt they work. Dr. Togut told me to cut them in half and wear for 23 hours per day. I haven't noticed a difference. Or, maybe it would be worse if I didn't use them. I don't know. I used to use a pain patch 7 years ago that I don't recall the name. But, that was more of a narcotic absorbtion patch instead of injesting I believe. It has been so long. I'm going to stick to the lidorderm and hope that helps. Good luck. Linda
