I am being sent for a CT scan next week as my specialist thinks I may have scarring in my lungs. He said that this could explain why I react so badly to colds and why my asthma still isn't fully controlled, although its a lot more controlled than it was this time last year. He also said that as I didn't get on with Singulair theres not a lot more he can offer me except pred as and when needed. Most of the allergy tests I had came back negative and the only allergens I reacted to at all were cats (I have dogs!) and house dust mite, but no more than most other people react to them.
My question is that if there is scarring, is it likely to change the way my asthma is treated or the available options?
