I left out of my initial post about itching that I have been itching like mad too. Every day. I switched from Zyrtech to Allegra once daily and I'm going to see an allergist at the end of the week. But if it is from the Camzyos I might have to have the heart-wall-shaving/cutting surgery.

I am also retaining water. I have to watch that closely because of Camzyos' risk of causing heart failure--water retention is one symptom of heart failure, though it's not necessarily from that.
