The soles of my feet hurt sometimes, I read that it could be one symptom of hypothyroid. I am hypothyroid. What I have found that helps my pain is Emu Oil. Rub to any painful areas really well. It goes deep into several layers of the skin, relieving pain. Also works for burns, sunburn, swollen joints etc. I carry it with me everywhere. Anyone with any itch, insect bites, painful gums, teeth or even for cleaning up, it works. Emu Oil is an Australian cure by the aborigines. It was introduced to me in US as a multi level marketing product. It now is in the mainstream so anyone has access. thru Amazon or Ebay.
