Allergic reaction maybe?!

I have strep!. I went to the doctor yesterday!. I was given an antibiotic shot and penicillin antibiotic pills to take!. My tonsils themselves feel better, but I just woke up and the back of the roof of my mouth is sore and that "hanging thing" is extremely swollen and is making it more difficult to breathe!. I'm not on the brink of death or anything, but it's concerning me because it hasn't been swollen with this strep at all!. Am I maybe having a reaction of some kind or is it normal for that thing to swell!? I've had strep 289743 times in my life and this has never occurred!. And I've also had penicillin before with no complications!. I'm 20 if that makes a difference too!. Thanks guys =)Www@Answer-Health@Com
