i have a degenerative bone disease and it has affected my lower back. i also have neuropathy in both feet. both conditions are very painful. i am on medications for both, but the lidoderm patch is an extra boost. some times my feet hurt so bad that i can't even stand a sheet on them. those are the nights that i am so happy the doctor prescribed the lidoderm patch. when you apply it, it is a cool wonderful feeling and you can wear them for up to 12 hours a day. the patch can be cut to size and one patch sometimes can be cut for two different areas. this patch is good for my back pain too. the area you have the pain has to be clean and dry when you apply, but will stick if you happen to get it damp after application. this patch is very good for temporary pain relief.
