This is great news for you! I feel fantastic. I just came back from a big walk with lots of uphill and I can't remember how long it has been since my breathing was so "good"! I was fortunate and the Camzyos kicked in pretty quickly for me and I noticed an improvement within days. It seems to continue to improve as well. I had some side effects during the first week, some nausea and an odd tingling in my lower legs. But no side effects at all after that. Happy to hear your good news - thanks for the update!
