"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 &#039;unsticks&#039;.  it is not re-appliable, can&#039;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&#039;t."
