Your words suggest you are having pharyngitis
.A throat swab culture sensitivity testing and blood investigations along with clinical examination will give the diagnosis.
Do warm saline gurgling four times daily.
Take CoAmoxiclav 625mg tablet thrice daily for five days.
500mg twice daily for three days and thereafter SOS.
Take Vit C 500mg
tablet once daily for a week.
If you are having too much cough
