Mrs. D,
I have PN; but since my L4-5 fusion, meds, etc., have a lot of pain in that same area. I do put the Lidoderm patch in the area you mentioned. Cutting in half has help to stay there without tape. But, and the big "but" (no pun intended) had no idea using the patch for a long period can possibly help interrup the pain signal. I would use the patch occasionally; maybe a couple in a month or two.

Thank you,

Gerry
