You have absolutely nothing to loose.
In fact, most of the time, that's what i do : i get at least 2 different opinions.
Not much than that, 'cause otherwise you'll spend your life in doctor's cabinets. And you know what? It happened like twice that 2 doctors completly contradicted each other.
In one of the case, i went with the one who didn't go back to his medecine book to find out what pills he should give me...
