3 weeks ago I ate something spicy and developed Gerd like symptoms, chest congestion feeling, then it started feeling like it's cough congestion, I have taken Augmentin for 5 days, I developed sore throat and post nasal drip started, I have ticklish feeling in nose like sneezing, I don't cough much but there's mucus and phlegm, no dry cough, fever is mild like 99-99.5°F but that is quite normal for me as I usually get that temperature, no breathing issue expect for the something stuck like feeling down my throat and chest, and sore throat. Is it because of Gerd and normal flu or I need to check for Corona..its been almost a month now with all these issues.
