Sorry to hear about all that. I've had some of the same kind of fun with Drs. In the past. I had cat scans, heart monitors, brain waive tests, and more. In the end, it turned out that I'm fine and that one of the other Drs was an idiot. If I had listened to him I'd be 32 yrs old with a pacemaker. I hope your story ends the same. All I can say is get multiple opinions and find a dr you trust/believe in. Ask around for good drs... best wishes for your health and your dad's.
