Tammy,
This is a question that really needs to be directed to a doctor who has examined you and seen your x-rays. Asthma can cause changes in your lungs over time, called airway remodeling, but I don't know that I've heard this referred to as "scarring" of the lungs.
If you're not getting the answers you need from your doctor, you have the right to seek a second opinion. I would encourage you to do so. You have the right to understand what is happening with your body.
To your health,
Kathi
