I'm 23 years old. Been smoking for about 1 year, about 4-5 cigs a day and also vaping sometimes. I recently had sudden onset shortness of breath which led me to a PFT. FVC is 81% predicted. Fev1/FVC is 87. Fev1 is 85% of predicted. No bronchodialator reversibility so doc said its probably not asthma. My X-ray showed that my lungs are hyperinflated, other than that everything is normal. CT scan came out completely normal. No emphesyma.
I still have been having shortness of breath for about 3 weeks now, it comes and goes. I mostly have discomfort breathing, chest feels itchy when I breathe and I feel something stuck in my wind pipe. No cough or mucus. ICS are not helping much, symptoms still come and go. Sometimes i feel completely normal. Doctor isnt sure what it is, i've been asked to report back after a week or two of ICS.
I just wanted to ask if someone else has similar symptoms. Could I have COPD at this age? My alpha-1 is within normal limits.
