What are the causes of swollen tonsils with white spots on the back of the throat?

Hello,

Welcome to icliniq.com. Yes, it is mostly a streptococcal infection, which is causing the sore throat and all his symptoms. And if your son has a white or yellowish spot, then it is more likely to be a sore throat than an oral thrush, because an oral thrush forms a uniform membrane rather than spots. Fever may not always present. You can get your son tested for streptococcus infection. I would suggest some advice for your son to try. Betadine gargles four times a day for around five days. Antibiotic capsule Augmentin (Amoxycillin and Clavulanic acid) 625 mg three times a day for five days. Antacid like tablet Pantoprazole 40 mg before breakfast, once a day for five days. Avoid cold food items. Tablet Paracetamol or Ibuprofen for pain, whenever needed. Consult your specialist doctor, discuss with him or her and start medications after their consent. Hope this helps your son and get back if you have any doubts.
