Well, I am a bit confused. Your older posts had a long list
of spinal problems, with discs and spurs etc.

If you do not have PN in your hands....I'd be inclined to think your problems are targeted in your spine.

Feet only implies to me:
possibilities:
1) foot structure issues (including compression of nerves)
2) compression of nerves in the spine
3) circulation problems-- do you have cold feet too? color changes?
4) did you take drugs (or are currently taking drugs) implicated in causing neuropathies?
5) Migraines can be due to many things. 15 a month seems like alot to me. There are specialty clinics that deal with chronic headache. In fact chronic use of pain relievers may actually cause headaches...they are now seen as MOH.
This is an example of a tertiary clinic that specializes in chronic pain/head pain and MOH:

I have been to 2 of their professional all day long conferences and know first hand how successful, professional, and medically creative and advanced they are.

I have severe longstanding osteoarthritis everywhere too. Alot in the spine. So I know how that can be. Spine, feet, hips, knees, even the jaw. Some is moving into my hands now. I am getting Heberden's nodes on my right hand.

I use very strong magnets for some of my pain. (last night even)
I have a thread on this:

The new very strong magnets are quite good at blocking pain.
I only use one at a time now of these larger plastic coated ones.
These would be a good test for you to try, various locations for the spine and feet.

The head however, that is a much different animal. I can't recommend the magnets for that location at this time. The FDA has approved strong magnetic therapy for resistant depressions, but evidence for safety on the head is not abundant at this time.

That thread has a link to a health site with a diagram of the nerves in the legs/spine and feet. You can use that as a template to put the magnets. That is how I do it.

I don't accept "idiopathic" often. There is typically always a trigger or reason for pain.
