I had puss pockets or tonsil stones in the back of my throat ( tonsils ) my throat was a little red, and had bad breath, went to one doctor they told me, " it might be tonsillitis" then went and got a second opinion and that doctor had told me its more likely a sinus infection, I was given antibiotics ( amoxicillin ) 3 times a day, for 10 days, the pus pockets had went away. Everything was fine up until today, I decided to check my mouth, and the white spots are back. No other problems, no fever, sore throat, strep, basically no pain or symptoms.. What could it be? If someone could let me know, I'd appreciate it!
