pain
"Lidoderm patch. Rated 6 and 1/2.   Used for 12 hours then off for 12. This was a fairly good addition to my pain treatment for spinal arthritis. I take NSAIDS, Tramadol and add this towards the end of the day when I feel my spine on fire.  It makes a difference but not sure a big enough difference to justify the cost.

Cons- must wear a non-waterproof patch for 12 hours. Patch is no good if you sweat even moderately as it 'unsticks'.  It is not re-appliable, can't take it off to readjust or for a shower so you have to get it right and time it right.

Pro- It does help in a manner that pain medicines and NSAIDS don't."
