I had hypertension that developed and had me scared to death about the 3rd class. I ended up going to an AME that does work for one of the big carriers. Heres how it went:
Him: "Oh, I see you marked hypertension, and are taking ..."
me: "yes..."
Him: "Oh... Well, in that case, I'm going to need blah, blah, blah..."
Me: Thump, "here it all is"
Him: "OH! GREAT! No problem! Here's your medical!"
What a relief! I can't stress enough, GET AN AME THAT DOES LOTS OF WORK (not just the "weekend AME"), and bring EVERYTHING they want from the get-go.
No problems!
Good luck!
