Hi there. An itch is a reactive feature. Usually there is either an underlying cause that is systemic related eg Metabolic changes, liver disease with jaundice etc or an allergic or hypersensitivity phenomenon to a host of food, air-borne or other allergens. More commonly just plain & simple dry skin may be the reason for the itch! Stress too may be a contributory factor & to a smaller extent climatic changes. Please visit a competent dermatologist to get to the root of the matter & this HCM site may point you in the right direction to someone of your choice & area. An antihistamine such as a simple AVIL tablet taken at bedtime might help in the interim. Good Luck & hope you are soon itch-free ! Dr Praveen Rodrigues MD
