It can also come from minute pockets (crypts) in the pharyngeal wall (called Keratosis pharyngis) Usually it is present always, and not only at the time of infection.

I forgot to say I had no tonsils. Does that make a difference? Hard yellowish particles did come out of them today....but they are still yellowish/white....
It may be keratin debris in the tonsillar crypt? Since the inflammation is just on its way out, I would suggest gargles with warm saline.
If there is no inflammation or pain, try to 'express' it out and gargle again.
The cervical lymph nodes will take a few more days to go away. Can't say, maybe some were there already before you had this infection?
