Hi – sorry you are still having some issues. I had my septal myectomy at the Mayo Clinic in Rochester Minnesota almost a year ago, October 1, 2019. Before the surgery I could barely walk without getting out of breath. Right after the surgery I did not have any of those symptoms anymore. The post op was really hard and the one thing I will never forget is my back pain which was the most painful thing I have ever experienced. Other than that I did not have the same symptoms as before the surgery. My breathing was pretty much back to normal shortly after surgery. It is now gone and I can excersie play tennis etc. What symptoms are you having? I'm hoping they will go away for the Mayo Clinic is great.
