I have been told by podiatry surgeon that the fat under the right ball of my foot has gone. I have had awful pain when walking. To help with the pain my hammer toe was removed to allow my toes to spread out more!!. I am however still getting pain when I walk. I was advised to get trainers that were well cushioned but so far nothing had helped. The surgeon says that nothing can be done only cushioning but nothing seems to have helped
