We went home figuring that was that - no asthma because the methacholine didn't affect him. But we got a call from the doctor saying that even though he never dropped, when he took that final allbuterol, he improved 40% from his baseline. Definitely asthma.
So now Jason is on steroids, a diskus and allbuterol. He is supposed to improve in 5 days. It has been almost 2 years of trying to treat this. I will be so relieved if this works.
