I have tenderness on the tuberosity of the fifth metatarsal. it hurts at times when I walk and has a burning feeling to it. If I apply pressure on the tuberosity with my finger or bump it, it really burns. How do I treat it? I do tend to walk on the outside of my foot, that s where my shoes wear, and I ve started walking much more than I used to, 3 to 5 miles a day.
