Oh my goodness! Well, let me share my opinion with you regarding the Mayo Clinic...they are the most amazing healthcare organization in the World! But I may be slightly biased.
I had open heart surgery at Mayo Rochester (affectionately known by some as "The Mothership". I had been misdiagnosed by my local cardiologist with four, maybe five different heart conditions, one of which was small vessel disease. To make the story longer (!) I was finally told by my local guy that I had a very rare condition called sub-aortic membrane and needed open heart surgery right away. If it was so rare, I thought, how many had the local heart surgeon done? I asked to be referred to Mayo and they said I had Hypertrophic Cardiomyopathy, obstructed. Never heard of it. Barely could spell it. I actually ended up needing to have open heart surgery, but I knew I was in the right place and relief flooded my thoughts.
I can't imagine having to have a re-do of a re-do! No wonder you are on pins and needles.
But rest assured...you are in the best place in the world with the top doctors in the world.
I am sorry you have to wait until August, but it's practically here! Are you close to the Mayo campus? I bet it's HOT there in August!
