I have not really used them for PN until this week.

For some reason, my right foot has had a pain in it only when I lie down.
I thought for a while I had irritated my instep wearing the flip flops I do
on vacation. I have to be careful what touches the tops of my feet, and
this one pair of slip ons has always worked for me.

But this nagging thing in my foot.. seemed to be coming from that knee (which has given me trouble in the past and has had MRI and injection of steroid once). The pain was mainly on the outer top portion of my foot. Not the toes. I woke me up almost every night since I got back from my vacation. I did ibuprofen, and that helped, but still it was there.

So I put 1/2 patch on the back of my knee on the thigh side, and bingo the
nerve that was being irritated, went to sleep!

Sometimes we feel the pain in the feet, and the actual nerve generation is
higher up. Using Lidoderms creatively can block some of that, if this is your
cause. I used the Lidoderms last fall/winter on that back of the knee location when my PT upset my knees too.

Many doctors balk at giving pain meds (which is cruel I think), but these same conservative doctors, often will spring for the non-habit forming Lidoderms.
However, I have found that understanding how to use them, is still a problem.
(I see many patients now in the long term care facilities being put on these, where I do my temp work). I get alot of calls on instructing the use of them to obtain pain relief. In my case, I find that I don't need them every day...whatever causes the nerve irritations, goes away for me and I can stop the patches.
There is a test spot, on the lateral side of each knee...feel around for it
when your knee is bent as in sitting in a chair...when you press it..and get a huge ouch...that is the meniscal nerve. My ortho showed it to me long ago, and I was amazed at how it changes on a daily basis. It is right in the center
of the outside of the knee..

Alot of pain can be found referring from the knee area. Been there myself.

All fibro patients should do the B12 daily (orally) since low B12 has been found
in the spinal fluid of these patients, during research.
