I’ve read everyone’s comments about phlegm dripping down the back of the throat. I had a really bad case of Covid (after being vaccinated and then several months later got a booster ). And since Sept of 2022 I suddenly started a blockage of my sinuses and the constant chocking and dripping of phlegm down the back of the throat. Dr. tried 2 rounds of antibiotics with no results. Also attempted Sudafed, Mucinex, nasal sprays, Nedi pot, and numerous other products (including a CT scan that showed nothing). There are days my voice gets very horse. Now I am having hair loss!! I found a website about Long Covid symptoms with over 200 Covid Long Haul symptoms listed, and hundreds of people also are also suffering from these symptoms. And Drs. are unfamiliar of how to treat them so far. Hopefully, someone can find the answers because after months of this I am physically getting worn out! Any advise would be gratefully appreciated!
