They thought it was
asthma. The last time which was this year, they hospitalized me
for a week. Which they ran lots of test and determined I have COPD. The symptoms I had were shortness of breath, tired, and coughing. Oxygen doesn't seem to help, medication wasn’t helping too (Spiriva and Advair plus nose sprays).although my doctor was wanted me to use it, to reduce symptoms and slow down progression but I could not tolerate them for long due to severe side effects.
