ITCHING  -  Generalised

Generalized itching can also be due to a variety of causes and may be more upsetting for the patient than a local itch. 

Allergies are always high on the list and the offending stimulus can be anything animal, vegetable or mineral. It may even be due to a medication that the person is taking. 

Infections can cause a generalized itch, especially conditions like chickenpox. Parasitic infections like scabies should also be considered. 

A number of underlying medical conditions can get people scratching. Liver and kidney disease, and certain blood disorders can all cause generalized itching. Sometimes even pregnancy will do it.
