My foot problems, which are much like yours, are from my Fibromyalgia. I just found this out. I have the numbness but also extreme pain when walking. Just wanted to let you know there might be one other possibility for your foot issues. Fibro affects the muscles, tendons and ligaments. It can also cause numbness in the feet, toes, hands and fingers.
I hope you get your answers soon too.
Take good care,
I can do anything through Jesus Christ who strengthens me. I have learned in whatever state I am in,to be content. Phillipians 4:11-13
