According to Dr Dearani of the Mayo Clinic in Rochester, while not common, return can happen.
I just underwent my second septal myectomy. This second was located in the apex of the left ventricle. On top of that Aortic valve regurgitation had changed from mild to severe. So they also did an Aortic valve replacement.
Im home now (2nd week) and feeling as well as can be expected.
It may not work for others, but has worked well for me to keep a regimen of taking tylenol on a schedule and then adding other pain meds as needed. I use a topical cream (approved by Mayo), heating pads and then the use of oxycodone for the break through pain. It has worked well to manage my discomfort.
Im very surprised to hear about the FL mayo wouldn’t accept insurance. As the Mayo accepts all, including Medicare.
I have had no more than the best care from Mayo. I personally wish that all hospitals/clinics worked on the same principles.
