Hi. Greetings. Dear Sir, I wish to enlighten you that itching and rashes 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. Most likely you have urticaria. This may need prolonged treatment for a few weeks to months with oral anti histamines to control you symptoms. You can apply calamine lotion over the hives for improvement of symptoms. Using a moisturizer for entire body soon after bath should also help Meet a dermatologist for detailed evaluation and treatment. Hope this helps .
