Hello and welcome to the forum. You've been through a lot! Thank you for your question but sorry you have to ask it! For those reading, quincy isperitonsillar abscess. https://www.medicalnewstoday.com/articles/324049 This is a painful, pus filled abscess in the back of the throat. Is that better and you are just seeing spots or do you still have symptoms? They do sometimes lance the abscess which it sounds like they do and often that and antibiotics will do the trick. However, sometimes the tonsils have to be removed. As to tonsilitis, that's a different diagnosis. Your doctor will likely swab the white spots. Keep in mind if you have no symptoms of a sore throat, it could be something like oral yeast infection from taking antibiotics. I would go back to the doctor to inquire what is going on. Also, as a tip, it helps to take a probiotic when taking antibiotics in terms of cutting down from the consequence of removing all bacteria, the bad AND the good. Let us know what the update is.
