Hi Mary,
We are all new to Camzyos and the unknown is unnerving. I hope it works for you. Speaking for myself (three weeks in) there have been no side effects and I have never felt this well in years. Although my obstruction was becoming debilitating, I found out that I would not qualify for heart surgery because the thickness of my septum wasn't thick enough to make surgery safe. So I wish the best for you and give it a bit of time. I think this site is comforting because we are a small group all in the same boat.
