Re: Do I have tonsil stones or cancer?
Because you are so young, throat cancer is very unlikely. It generally appears in people over 50. Tonsil stones are much much more common. Also, acid reflux can cause throat irritation.
There's no reason any of this should cause a problem with the wisdom tooth extraction. Fatal throat swelling is caused by anaphylaxis, not by sore throats--and oral surgeons keep medicine to deal with that sort of thing anyway.
So, there are three possible problems here, acid reflux, wisdom teeth, and tonsil stones. Any of them can cause discomfort and swollen lymph node. The teeth are about to be dealt with. Next, you can make an appointment with a doctor to look at the tonsils. They might need to come out eventually.
