Chronic urticaria during humid season.

Every year since 2017, during the humid season around July-August I develop chronic urticaria with thick rashes all over the body and with very high itching thoughout the body. I tried with different medications: allopathy, homoepathy and ayurvedic. Every year during medication it comes under control and after Feb-March the urticaria symptoms also go away. Again during July-August it develops. This cycle is just going on year by year. I am frustrated and just requesting anyone who has relevant info, is this uncurable? I have visited nearly 6-7 doctors (of different area) during these years and followed the courses very promptly. When I sweat like sticky as it happens in hot humid weather, itching and rashes comes back. Please help if anyone can 🙏
