What do about my feet? my feet have a bad rash on he side and crack feetand also pain.

To start with...: It may be chronic athlete's foot. The best otc medication (in my opinion) is lotrimin (clotrimazole) ultra. Socks should be a synthetic material like those manufactured by thorlo [http://www.Thorlo.Com/]. Dry the inside of your shoes by placing them up-side down over an air return vent at home overnight. If this doesn't make things better in a couple days, see a podiatrist.
