Greetings. Dear Sir, I wish to enlighten you that itcing and hives could be due to many many reasons and may be tough for us to diagnose with the limited history you have provided. I would wish to request you to send images of the rashes you have for confirmation. Urticaria may need prolonged treatment for a few weeks to months with oral anti histamines to control you symptoms. It is mostly an allergic reaction to some unidentified internal or external stimulus. You can apply calamine lotion for improvement of symptoms. Meet a qualified dermatologist for detailed evaluation and treatment. Hope this helps . warm regards, Dr Govind S Mittal.

Greetings. Whole body itching could be because of many reasons, both skin related and systemic causes. Cetrizine will only reduce your itching momentarily, but if there is an underlying cause, it tends to recur. are you a diabetic or do U have thyroid problem? U need to be thoroughly evaluated with blood tests and examination to rule out any underlying problem. Please visit a qualified Dermatologist for the same.
