Swollen gums with tonsillitis, is this normal?

Hello, I saw my doctor on Thursday and have been prescribed antibiotics + 400mg of ibuprofen three times a day for tonsillitis. I’m in a lot of pain and each day I wake up various parts of my gums are swollen and I can’t chew food on the left side of my mouth. Is there something more serious going on or is this normal? Some parts of my mouth feel as though I have canker sores.

I’m a 30 year old female, non-smoker, haven’t had tonsillitis since I was in my early 20s. I’m 69kg and 170cm tall. No other previous significant medical issues.
