is it painful itching on only one half of your body? Could be shingles...
Alternatively, it could be Urticaria (Sp?) which is a common skin complaint where you come out in itchy hives for no apparent reason. You may need hydrocortisoids or something like that. See your doc.
Have you eaten something like shellfish or strawberries recently?

Sounds very much like an allergy as everyone implied. Once you find the cause (could be internal- food or something external) it should go fairly quickly, but that doesn't rule out other skin problems unless a doctor takes a look at it.
