I cannot tell if the pain and swelling im feeling is still from tonsillitis or an abscess. its only on one side?

With tonsillitis you only see the enlarged tonsil and exudate but in peritonsillar abscess you will see the engorged swelling of the pharyngeal structure next to the inflammed tonsil and it pushes to tonsil to the uvula. High fever and painful swallowing are prominent in peritonsillar abscess and you are quite sick, much more than tonsillitis. Please see your doctor or visit urgent care.

That's not a decision for you to make. It has to be made by a trained health care practitioner. Important that you see your Physician or Urgent Care. If you have a tonsillar abscess or tonsillitis, seek evaluation by a specialist ENT, an Otolaryngologist. If your problem is dental, rather than medical, evaluation by your Dentist may be in order. Don't try to self-diagnose. See a pro.
