I have 2 toes that are numb and the bottom of my heal hurt and the bottom side of my heal burn. I took an xray thinking I had a heal spur but it came back negative. I was told to take 1000 mgs for 7 days and it helped but now the pain, numbness and burning sensation is back. I don't have any symptoms of diabeties. I am over weight. I am at a loss for what this is and what to do about it. Any one with thoughts about this would be appreciated.
