Hi. Greetings. Dear Sir, I wish to enlighten you that you have urticaria - could be due to many many reasons and may be tough for us to diagnose with the limited history you have provided. This will need treatment for a few weeks with oral anti histamines to control your symptoms along with evaluation of the cause. You can apply calamine lotion for improvement of symptoms. Meet a qualified dermatologist for detailed evaluation and treatment at the earliest. Hope this helps .Warm regards, Dr Govind Suresh Mittal. Bengaluru
