I found only one place worked for Lidoderm patches for me.
Right at the top of the thigh where the nerve exists the abdomen.
Also it takes several days to work up to the nerve in order to
suppress signals. It is not a quick fix.

MP comes from the back. It is also present in people wearing tight waist belts, etc, and also tight jeans. The nerve can be damaged while traveling thru the abdomen...which is how mine occurred.

I'd really suggest you get another drug, not in the ACE family for a while and see what happens. I am another person, since my ordeal. I was on those evil drugs (vasotec, accupril, and finally lisinopril) for 10 yrs! Until the bradykinin built up to overflow into other bodily systems... neither I nor my doctor suspected a thing.

I did not find lidocaine worked at the end points of pain in the thigh. Only at the location, shown on that diagram I gave you the link to.
Some people do get MP from lumbar compressions, but that is less common.
