I am a 32 year old male, and for work I need to be on my feet for about 10 hours a day, I have been doing this for some years now and it is starting to get really sore, to a point were it feels like I am standing on the bone, I have seen many doctors who just say I have sensitive feet. I have read that females have been know to get there own fat injected into there feet for padding. I would like to know would this be ideal and would it help to pad the heel, I have tried orthotics without success
