No offense to your doctor but a cardiologist is usually the one to assess arterial issues. They can do an ankle brachial index, where they do a BP of your arms and legs, among other things. Or did your doc suggest that?

Inserts won't hurt but usually, if it is plantar fasciitis, it can require physical therapy too, for the best outcome.

Do you have any sore spots on your back/butt/hips? Feel around and see if there is. Any weakness in your trunk muscles can throw off the spine. That can cause pain anywhere in your legs too.

Whatever is going on, I hope you get answers and relief from it.
