Hi S.,
If I were you I'd go see a foot specialist. I work for one and sometimes with what your going through you could have a neuroma. Its a nerve tumor that can cause pain, numbness, and tingling in your toes and can be very painful almost to the point you can't walk or can't walk at all just like what your going through. The only thing is is if you've had MRI's of your feet it would've shown up. We have whats called a diagnostic ultrasound its just like looking for a baby but looking inside your foot. It can show if you have a neuroma or if something else is going on like a pinched nerve or bursa. For your hands I can't help you. It may be related it may not but I know when your feet hurt everything hurts. I would just get your feet looked at see what they say. It wouldn't hurt. Sometimes even a foot doctor can help you figure out other problems my employer has helped a few of our patients get the correct diagnoses to get treatment for there problem no one else could figure out it sounds wierd but sometimes it can all be related. I can't promise you though but again it wouldn't hurt to get your feet looked at. Hope I was some help and good luck.
