Can this be reversed. I don't have insurance for one more week so I can't go to a doctor. Is there anything I should be doing in the meantime to help my situation? It hurts and it seems that my toenails are getting soft and look like they are going to come off. Is this from lack of blood flow to my feet? What can I do about this? The red purplish is just on the top of my feet, I have no problem with the bottom of my feet. It itches really bad too.
