Got Covid 4 weeks ago, got better two weeks later. This weekend I went out for my first walk, about an hour. Although I didn't have any lung issues during the really-ill period, I definitly can't walk as fast or long as I used to, one hour felt more like two or three. I really had to pace myself. I broke out into heavy sweating going up a small hill. When I got home, I laid down in bed and dozed the rest of the day. Pure exhaustion. After I got 'better' I thought it was comparable in severity to a bad flu. It's becoming rapidly apparent that the real impact shows itself after sickbed. I'm 33. I feel like I've aged a few decades in the past month. I really hope this will pass.
