During tonsil treatment new sore behind uvula and small white & red dots on left side of roof of mouth. only left tonsil infected.actually mono or reaction to meds like sjs blister? chills nofever

Otolaryngologist: Mono usually affects both tonsils and a routine throat culture checks for strep. A viral infection like herpes is a possibility. Sjs(stevens johnson syndrome) doesn't sound likely. I recommend an evaluation by an otolaryngologist for diagnosis and treatment.

Tonsil lesions: You might have a viral infection on top of the bacterial one. I suppose you have been on antibiotics for the tonsil infection. I would watch the mouth lesions and finish the antibiotic. Gargle with warm salt water and take Motrin or tylenol (acetaminophen) for pain. Good luck.
