I have high arches too. Even needed girl shoes as a toddler in the 1980's to get enough support lol. Too young to remember so it's okay.

If you're able to pinpoint the discomforts and historical perspective I'd imagine a physician could as well. Have you had ultrasound?

Today, I'm going to see an ultrasound / PRP injection doctor (plasma-rich platelet). Saw my pain specialist yesterday who put me on Buprenorphine from extremely low-dosing of Tylenol 3. They gave me stomach aches and I stopped taking them knowing pain would get worse, and did. See how that goes. Had high hopes until he said PRP doesn't work for nerve damage, only cartilage. Still going to go talk though. If anything, I want my nerves mapped to figure out where the nerve damage is if only for peace of mind and to have a better understanding of my body.
