Dueling Doctors

I went to my asthma doctor for my 4 month check up today. He knew that I was referred to an ENT (ears, nose, throat) specialist in July. I gave him the results of my 4 visits to the ENT. The ENT wants me to start allergy shots because I am allergic to many things. Well, my asthma doc said it would not be advisable since I was unable to complete the shots a number of years back. So what do you do when your doctors don't agree? Yep, I'm going with the advice of the one who causes me less hassle in life--the asthma doc.
