No, I did not have lung issues before Covid. I did have acute pneumonia with Covid. I am actually asking the question for a friend, however, I still have Shortness of Breath with exertion - sometimes just minor exertion, like unloading the dishwasher. I never know whether to push myself. If I feel ok while doing something, like weeding, I don't stop to rest. Last week I had a major episode about 30 minutes after gardening - not fun. It's been at least a year since my lung tests - wondering if I should revisit them with my doctor.
