My sister gets sucha bad itch on the bottom of her foot that the doctor told her there is nothing to do for it. I can't explain how serious it gets other than she almost looks like she's going into a seizure from trying to keep scratching it. Sometimes this goes on for 2 hours. With todays medicine is there nothing that can be done for this or does she have to go to Philadelphia to a big city doctor who might be able to help her. I appreciate any suggestions you can give me.
