Hi and Welcome to HCM.
Thank you for the query.
the problem you are suffering from is just a congested pharynx,resulting in
acute pharyngitis.
if I were your doctor,I would treat you with the following
1.An antibiotic for the infection: Tab.
azithromycin 500mg PO once daily after meals., for 3 days.
2.A pain killer : tab.
paracetamol 650 mg PO twice a day after meals 3 days.
3.Salt and Luke warm water gargling thrice a day.
4.Drink lots of water.
This definitely would bring down your symptoms gradually.If they still persist,i recommend you to show to an
ENT specialist,for further examination and work-ups.
Looking at your other symptoms,tab.
Augmentin usually washes off the intestinal bacteria,which help in digestion of the food,resulting in diarrhea.
tab.Sporolac- 2tabs each time,thrice a day for 3 days would help you with the diarrhea. This would help you rebuilt the intestinal flora.
Have curd/yogurt in the afternoon.
Thank You.
Stay healthy.
