Hello, jcorry.....
It is a very good idea to go to an AME - an aviation medical exam, even a class 2, could end up saving you pots of money if they find something that would keep you from your ambition of becoming a commercial pilot, so getting the medical before starting the training is a first class idea!
Even if there were a problem, becoming a commercial pilot is not a lot of fun these days, if you read the moans and groans of those sitting in the pointy ends pushing buttons. There are a lot of ways to enjoy flying; probably the best is to have a qualification that enables you to fly for pleasure, with a job that pays properly.... These days some airlines are making hopefuls to pay for type ratings, and then they still don't get a job.
