I Saw My Physician On Monday And Was Determined Strep

I saw my Physician on Monday and was determined strep throat... And started antibiotics .. It's now Thursday I have fever, extreme discomfort swallowing... Will I see any give on my symptoms, it only in one tonsil, however it is a blustery ugly mess.. What luck... I was blown up balloons for my lil cousins last week, when they had visited ...never again
