Should I be worried with these spirometry results?

I am a very active, typically healthy, active, 29 year old female. For as long as I can remember I have had troubles with breathing.

When I was younger I was diagnosed with asthma. To my recollection this diagnosis was based merely off of symptoms alone.

I have found myself short of breath walking up stairs, talking, even standing and doing dishes. I began to seek medical attention and through process of elimination, it appears that I may have a restrictive problem with my lungs.

I was going to have a amnitol challenge done with my spirometry, however, the tech. decided the challenge was no longer necessary after seeing my results from the spirometery. I also have values for diffusing capacity and resistance.

Here are the results:

Vtg (Raw)   Liters                                   2.44

I am awaiting the next step, but I was told not to work out or exert myself until further notice. I really enjoy working out. I was told that it could be scar tissue, and if so there is no treatment or anything to make you more comfortable. Thank you in advance for any help!
