It's hard to say. Is it in both feet? For me, I had a burning pain in both feet that came on pretty much overnight AFTER lowering my blood sugar to normal range about 6 weeks following diagnosis. 18 months later, and it still bothers me. It varies in intensity. I never had the numbness, or the pins and needles you describe.
Sorry, I know I am not much help. Just letting you know you are not alone! If you don't have it in both feet, it could just be a pinched nerve.
