Hi Herrington,
Welcome to Heathcare Magic Physician's Desk!
You are probably having an upper
respiratory tract infection which is mostly of viral origin.
I would suggest you to have lukewarm saline gargles and to have good
oral hygiene.
For
tiredness and headache you can take paracetamol/
acetaminophen 500mg as required for comfort up to 6times a day.
The problem is expected to subside in coming 3-4 days.
Wish you a great health!
