hello and welcome to HCM,
From the symptoms you have mentioned you seem to be getting an episode of acute tonsillitis
which may have spread on to your jaw.
When i get a patient like this i would usually do these:
1.Since your tonsils were covered with a patch i would advice you take a throat swab for culture and sensitivity and start a proper antibiotic depending on the report.
2.I may advice you to take injectable medication for faster and more effective symptom relief
3. Get an endoscopy
and CT PNS to further evaluate your sinus
problem and give a proper treatment
4. Get an dental opinion regarding the jaw swelling to rule out any dental problem
meanwhile take only warm fluids
Hope you get well soon
