Hello. Thank you for asking at HCM. I went through your history and from your history I think you may have what we call chronic urticaria . It is important to identify the cause of chronic urticaria, it is not always allergic. So I would like to ask you in detail about possible causes like excessive sweating, sun exposure, contact with hot/cold water, any drug intake by you, symptoms of intestinal worms, viral infections, thyroid disorders, etc. And I would also suggest you investigations like CBC, ESR, CRP, thyroid tests, urine & stool examination. If these investigations reveal any cause, I would treat the cause. If these do not reveal any cause, I would suggest you to consult an Allergist who will ask you in detail and suggest you further investigations to look for cause of urticaria. Till your cause is identified, I would suggest you to take Levocetirizine in morning and Montelukast and Hydroyzine in evening which may control the symptoms. Personally I would not suggest corticosteroids (like diprofros) if these medicines are effective to control your symptoms. Also, avoidance of too spicy food, avoidance of woolen & tight clothes, avoidance of activities causing excessive sweating, etc measures will also help. Duration of chronic urticaria can only by predicted if cause is found. I hope this will make things clear to you and will be helpful. Wish you the best of the health. Regards.
