Wheezy, sats 93 at night, exhausted, cough, aching , shortness of breath, temperature but negative covid test. I'm not sure if I should see a GP or they will just tell me to rest at home. Viral probably. Day 2 off sick. How long should I be off? I'm a teacher so can't take it easy at work. But feel so guilty. Just walking around at home for a but makes me shattered and I've been in bed most of the time. Opinions please.
