chronic cough. I have allergies, today I was outside pulling weeds and started to cough and after a minute my airway closed. couldn t get air nasally or orally, I had an inhaler from the last time I was sick with bronchitis and took 3 puffs, airway started to open. this is not the first time this had happened. Do I have asthma? lung sounds are clear, CXR good, At times I do expectorated a clear mucus,
