You know even if your first doctor was right i'd say get that second opinion. Obviously your not happy with that doctor, i'm going through the same thing with mine. I feel it's harder on you when you feel your doctor is not listening to you. When I get the money I will be going to a different doctor.
And you know what now that I think about it my doctor gets all pissy if I ask to see my lab results, all she will tell me is if it's good or bad. OOOooooohhh this is just making me madder now that im thinking about it so I COMPLETELY understand your frustration.
Good luck I hope this new place helps you.
