Hi and welcome,
I hear and understand your concern about military health care. It has been my experience that recognizing and diagnosing problems can be a bit lacking although once you get a firm diagnosis the care should be excellent. In any event whether govt. or civilian we need to be our own health advocates and it sounds like you are on the ball with that.

Sorry if I missed your age, but I would be concerned about prostrate issues also and that is something I would address immediately.

The other thing and I know this might not be a popular suggestion but if you are not able to get a second opinion through your current situation I personally would pony up the money and get one from a MS specialist on the outside if you are concerned that you were misdiagnosed.

Best wishes and please keep us posted.
