Tonsillitis

My doctor prescribed me a 5 day zpack for tonsillitis and I took it she said it stays in your system for 10 days. by the 3rd day I was feeling much better and today is day 8 I feel completely fine and my lymph nodes are less swollen but I still have the white spots on my 1 tonsil not as bad as it was but I was wondering if you had tonsillitis when was it gone completely?
