Does this sound like long covid?
I may have gotten covid in March 2020, though we don't know because getting tested wasn't a thing then. I've been very sick ever since. I have abdominal pain, nausea, reduced appetite, weight loss, muscle aches, joint pains, shortness of breath after just climbing stairs, I can't walk more than a few feet some days because of the pain and pressure I feel around my solar plexus, I can't exercise, standing up increases my heart rate, I always feel hot and can't stand breathing in humid air, so I can't take showers, I had insomnia and disrupted sleep, always tired even after a good sleep, I've been through just about every medical test and found nothing. Any one else experiencing something like this?
