I noticed that I sweat much less before my diagnosis. I can’t put my finger on when this started, but there was a time before my diagnosis that I had night sweats and sweat a lot. I think the no sweating has maybe been the last few years. I am taking HU for ET since March 2025, and my platelets have come down and I am sweating again! I have not seen this discussed on the message boards on MPNs, so very interested in your experience.
