I was perfectly fine an hour ago and then my right nostril started feeling tingling followed by a lot of sneezing! Now I am extremely congestive and my throat is starting to get sore. I remember reading something about what to take if you get COVID but I can't recall what was recommended. I am hoping this is just an allergic reaction to something but since I have been in and out of doctor's offices this week and around a co-worker who just recovered from COVID, there's a possibility this may be more than an allergic. Any suggestions as to what I should take in case this would be COVID?
