Over the course of the next month, Brian slowly got better. After the first week, we started to see signs that the cough was becoming less frequent. Into the second month, he was completely normal. I can't help but think of how the story would have ended had we not gone to the Mayo Clinic.
I think the Moral of the Story is to follow your motherly instincts when it comes to the health of your children. Make sure to get a second or even a third opinion when you feel it is necessary. Don't just take the word of a doctor as being 100 percent correct. We owe it to ourselves to do our own research.
