Is this normal for tonsillitis?

about 4 days ago i randomly got the chills and became very weak. next thing I knew, the very next day i was in the hospital rocking back and forth, with a fever over 100F unable to swallow and ping out every few minutes. My doctor told me i had tonsillitis. She prescribed some penicillin and it took a few days for my mom to actually go out and get it for me. but since that doctors visit, i noticed my symptoms worsening. My tongue is very swollen, to the point i cannot fully close my mouth without biting on my tongue, which now has blisters all along the sides. My cheeks and gums are full of the little white patches i found on my tonsils and the roof of my mouth is coated with them, making it impossible to ingest anything. Whats really weird is even though i keep gargling with hot water and salt 2 times a day it seems to have now spread to my lips. my bottom lip is swollen and puffy, there are giant whit blisters on them about the size of my middle fingernail. I`ve thought about going back to the doctor but im afraid i will just waste my time. How long does this usually last anyways?
