I really dislike the fact that I might know what this is. 😂
When I started my breast cancer journey, it included tamoxifen, then anastrozole, which made me have terrible hot flashes, especially if I get warm with weather or warm buildings. That will trigger a bad one really quick, and they come and stay for a while. This is a “Vaso” response. The opening and closing of all the tiny blood vessels everywhere, made me feel like I was itching everywhere all at once, from about the waist up.
I don’t know if this is the same as what you have, but I can tell you the itching portion of the program subsided over the first year, after I quit taking anastrazole. I wish I could say the same of the hot flashes. Let’s just say, I am not looking forward to summer. 🥵
I am glad you are in your last year of anastrozole, does this sound like the itching you have?
