So if you suspect a back compression, that is where to put your patch. It took 2 weeks of everyday patching on my upper thigh, where the nerve exits the abdomen to block the excessive firing of that nerve. After almost a decade of pain, I was in a remission, which continues today. But HEAT -- that is a big no no. Some rare times if I over extend the leg, I will get twingey reminders of what used to be...I consider that a warning and back off that activity right away!

Some people who have bone marrow grafts taken from the iliac crest get MP from damage there. But you can have it from compression in the spine as well, and damage in the abdomen from surgeries there.
