Many possibilities..: Itchy rashes can be from many causes, such as: allergic reactions to various things (such as parts of shoes or socks), hives, fungal skin infections, viral or bacterial infections, medication causes, heat rashes, reactions to creams or lotions, internal problems (such as kidney disease, auto-immune disease), etc... That means a rash that persists or is worrisome should be checked by a doctor.
