I Had A Heller Myotomy, And Overall It Was Successful.

I had a Heller Myotomy, and overall it was successful. The problem that I have is that I now can't use my BiPap machine. (I had excellent rate of using my BIPAP before surgery and surgery was Feb 10th)
When I put on the BiPAP, my throat closes down and I can't breathe. My pulmonary doctor lower the intensity of the air flow, but that didn't help.
