Hope you get well soon. Rest is good apparently helps to minimise long Covid. Similar thing happened to me. First my dad started to get a scratchy throat, did a RAT test and it was covid positive. Then my throat started getting scratchy also did a test Covid positive and then my mum who we thought had a stomach bug also came Covid positive. Been soothing myself with a warmed up mix of apple cider vinegar and honey. Interesting to see how different our symptoms are, my dad just got a sore throat, I got the sore throat with congestion and while my mum got an upset stomach she avoided the sore throat and any congestion issues.
