I'm glad you got over your bronchitis.
My neighbor downstairs was diagnosed with COPD. I'm almost 74. She's older than me, and has always been active. I've never smoked...neither has she. It took them a long time to diagnose her problem, and finally get her to the point where she wasn't having to go to the emergency room because she couldn't breathe. She still goes out for walks, weather permitting. She doesn't let her illness keep her down.
The son of a friend of mine worked with a guy who was experiencing Covid symptoms. Both men were tested three times, over a period of time, before both finally tested positive. By the time my friend's son got his positive test result back, it had been so long that the doctor told him he wasn't infectious any more. He's married with two young sons. The whole family (my friends, their three sons, and all their kids) went on vacation together, stayed in a house in Delaware this past summer, and nobody got Covid.
I’m 66 with seasonal asthma but surprisingly this didn’t bother my asthma as much as bronchitis usually does. I called her pretty fast instead of waiting because of COVID so I got medicated sooner. The worst part for me was the intense stomach pain. I never had that with regular bronchitis. I eventually had to take my daughter’s prescription Zantac to get any relief.
