Severe chesty cough all weekend. Comes in bouts with thick yellow phlegm. (Sorry). I still have an appetite and don’t have any other major symptoms bit of a slight blocked nose but that’s it. It is all just my chest. I had a dry cough this week and chest tightness. Over the weekend it suddenly turned chesty, and feels like a weight on my chest too. But I’ve no fever etc. I did two Covid tests- negative. As a result I feel it’s probably not contagious with the lack of fever etc and that I should be at work. But then I’m wondering AIBU because it is a productive cough, and with the weight feeling on my chest talking to classes will be harder! Why is it so hard to make these decisions as a teacher argh!
