You'll definitely find a goldmine of information here. Read, compare, question, and be a fearless self-advocate. We're here to help if you have specific questions, but no one can give a one-time post that would be enough to prepare you for everything you'd want or need to know. Don't be a stranger here. But do something. Take some action. Today. Right now. It's good that you were committed to exercise in the past because that will be a key part of your post-surgical regime if you decide to move forward.
Oh, and.... welcome.
