Lil Chief,
I'm not trying to tell you how to run your life (God knows I have a hard enough time with mine) But I would wait until after retirement to get the sergery. You will be able to pick your own medical staff of more then quilified Dr.s with proven records. This is not always true of Navy surgens as I am sure after 20+ years I'm sure you know. Thats just my advice. But you know what they say about opinions. Good luck either way.
