hello and welcome to HCM,
I know we often try to avoid going to the doctor because of many reasons and try the home and local remedies first! But you definitely need to go and see a doctor because pus pockets in the tonsils are very dangerous (of course only the doctor can confirm that they are pus pockets)
Also since your symptoms are so severe that you are unable to sleep and swallow you may in all probability require proper medication so that the infection can be controlled.
Meanwhile try salt water gargling and avoid cold
water and take lots of warm water
get well soon
