Its not just second opinions. I had to find the RIGHT doctor to get my heart fixed. That meant a six hour drive to another city, a night in a hotel and then see the doc and drive home.
Totally worth it.
Went back in a month, got tests, went back home again.
Drove down the 3rd time in six weeks, had the procedure, came home, been fine over a year now.

Yes, the gas and hotels costs MONEY. Total of five hotel nights and 1800 miles at 25mpg/$4 a gallon - But in the end, it was all worth it. Not all doctors are equal.
I talked to others with my condition and went with the guy that sounded like the right guy. He was.
