Additional Information: Prior to the vaccination, the patient was not diagnosed with COVID-19. The patient had no known allergies. Other medications within two weeks of vaccination included an unspecified probiotic and multivitamin. Twelve days after the second vaccine, the patient started feeling sinus pressure and developed cold symptoms. For about a week, he fought fatigue, runny nose, phlegm in coughs, and persistent green/yellow snot. About a week later the symptoms subsided for a day or so. Since then, his sinuses have been continuously inflamed and he still has snot to the point where he is blowing his nose every 10-15 minutes to release the up to dime-sized hunks of snot. It's been a month since initial symptoms and roughly three weeks of persistent sinus irritation/inflammation and large snot masses that make the patient feel like he is in the midst of a pesky cold. The patient was tested for COVID-19 on 04Dec2021, which was negative.  No follow-up attempts are possible. No further information is expected.
