Thank you for asking at HCM.
I went through your history and would like to make following suggestions to you:
1. Were I treating you, I would prescribe you an antihistamine like fexofenadine/hydroxyzine/cetirizine
for 1-2 weeks (depending upon response).
I would also add monteulkast to your treatment.
2. I would also suggest you a course of anti-parasitic drugs as you have a history of travel. Sometimes intestinal worms can cause itching & hives
3. Personally, I would suggest you to avoid wearing tight-fitting or woolen clothes. Loose-fitting, cotton clothes will be the best option in my opinion.
4. Please avoid activities causing excessive sweating
and hot,spicy foods for a few days. It may help.
Hope above suggestions will be helpful to you.
Should you have any other query, please feel free to ask at HCM.
Wish you a fast recovery and the best of the health.
Thank you & Regards.
