Hello ma'am, I'm sorry to read about your troubles! Unfortunately, it is impossible to determine if you have tonsillitis, as this requires a diagnosis, which can only be done by a doctor. What I can suggest is to take acetaminophen (Tylenol and other brands) for the pain, as well as lozenges like Halls or Fisherman's Friend for local relief. I also encourage you to drink plenty of fluids, cold or hot, as you prefer
In addition, the description of your situation leads me to suggest a rapid test for COVID. If you do not have a test, do not go to the pharmacy. Send a loved one or request delivery.
If you have other symptoms or questions, I will be happy to help.
If it persists for more than 7 days or gets worse, you will need to see a doctor.
