Well, you said it yourself...

Your doctor's "opinion" is just that. It is not a fact, but an opinion.

If you know your trigger, then you have some foot structural problem. It just hasn't manifested itself in testing yet.

Have you tried topical products to see if they help or work at all?

Biofreeze, or Lidoderm patches? Magnets?

And I like the Idiopath term. We should have a thread on the SubForum with that title!?

If some nerves were injured in your feet, then focusing on healing them up may be your course of action. As long as you don't trigger them in the same way again! I know for myself, I cannot wear certain types of shoes anymore. The tops of my feet are very sensitive now.

Try this test. Take a hard object, like a butter knife handle and bonk your instep in a couple of places. Don't need a heavy bonk, but just a modest dink with it. If you feel jolts down to your toes in some places, that is called the Tinel's sign. Meaning some compression or nerve issues are present. You can do this on the wrist too.

The foot is highly complex. Fluid retention there causes problems, and that can change as the day goes on. I know for myself, I have alot of tendon ganglions that I was born with, that swell up and then go down. My left surgical foot is now giving me issues --pain in the ankle coming and going. I foresee some intervention for that coming. I am thinking a laser surgery on the remaining hemangioma I have there under the skin.

It doesn't take much to mess up your feet IMO. So I would focus on healing now. That high arch will always be problematic for you too.
