Good for you for getting this figured out and under control!!!

I struggled with breathing impairment all last spring - it came on so gradually that I didn't really think much of it. Ultimately I really had a hard time filling my lungs and breathing - especially on climbs. Wheezing and super heavy breathing and just not able to push it. It was VERY discouraging. I thought I was just out of shape or not training hard enough. We initially thought it was asthma, but inhalers really didn't help. I wasn't positive for allergies. Finally, after a hospital stint, it turned out it was many blood clots in both of my lungs!

After 6 months treatment last year, and now that my "issue" is 100% resolved, I feel like I have completely new lungs. I totally get what you're saying - isn't it GREAT to be able to use your lungs??!!
