Similar Pain
 

I started with the burning feet and big toe pain. That particular pain has subsided but the feet still burn especially on cold floors. Now I drove 9 hours the other day and developeddevelopedpain Iin my calf and knees. I also noticed walking last Saturday I got very heavy achy legs a first for that was walking over 2 miles a day.
Check with a good chiropractor the leg issue could be an issue he could help with mine helps me even with the PN by keeping my neck adjusted.
I don't know where you live but if close to a teaching hospital try to see a neurologist there they usually are more up to date. I live near Baylor in Dallas so i was fortunate.
Best of luck to you
