Thanks for your query
Your words suggest you are having tonsillitis
.Your tests for bacterial infection came negative ... so either there might be bacterial superinfection
over previous viral infection or there might be false negative results.Repeat the tests and also get a throat swab culture sensitivity testing done.Some blood investigations may be needed.
Dont wait for the culture reports and start Coamoxiclav 625mg thrice daily for five days.Depending on the culture sensitivity reports the antibiotics may be modified if needed.
500 mg twice daily for three days and thereafter sos.
Take Vit C 500 mg once daily for a week.
Do warm saline gargling four times daily for five days.
There are chances of ear infection
spreading to meninges causing meningitis.So be careful and get a medical check up from an ENT specialist
.Dont self medicate without prescription.
Update here how you stay.
Hope this helps.
