I Have COVID

After getting both shots, my first booster, wearing a face mask, working from home and being very careful about being in crowded areas I have now come down with COVID. Last Tuesday I thought I was getting the Flu but my body temperature went to between 102 and 103 so I got a COVID test and it was positive. This was done at a testing center not at home. Friday I was given a medication called PAXLOVID, taking 3 pills twice a day. No I have no aches/pains no problem breathing but people tell me I sound congested. Not sneezing or coughing so I don't know what to do. Any suggestions?
