I understand your confusion in this whirlwind. Just the idea that you appear to be a surgical candidate is a good thing. However, you have every right to expect to understand what the planned surgery is all about, while you accept that things don't always go as planned. Also, while you do need to move very quickly, you also need to take a deep breathe and ask yourself if you have the right surgeon for the procedure. It is tough to find the right balance between understanding your options and being aggressive and quick.
Best wishes to you. Please let us know you how proceed.
