Hello Samit, Thank you for asking at HCM. I went through your history and would like to make you suggestions as follows: 1. Were I treating you, I would suggest you a regular antihistamine like cetirizine/levocetirizine/fexofenadine along with montelukast for 2-4 weeks (depending upon response). 2. I also prescribe a short course of anti-parasitic medicine for intestinal worms as sometimes worms can also cause such symptoms and are common in many parts of India. 3. I would suggest you to avoid activities causing excessive sweating and hot/spicy foods. I also advise my such patients to avoid wearing tight-fitting, woolen/synthetic type of clothes and wear loose-fitting, cotton clothes if possible. 4. Please do not scratch the itchy areas; scratching aggravates itching. I would suggest you to apply lotion like calamine over the itchy areas. 5. A multivitamin-multimineral containing vitamins A,D,E and zinc, selenium etc may also help. Hope above measures will be helpful to you. Should you have any other query, please feel free to ask at HCM. Wish you the best of the health. Thank you & Regards.
