About 4 months ago, I got a fever, sore throat, really swollen gums
, and a blister on my lower lip. I was on vacation at the time, and as soon as i got back home, i went to my doctor and she swabbed for strep throat. turns out, it was. however, my swollen gums never went away and they were kind of receding (which makes me think that I also have gingivitis) I'm really wondering if all this has caused some form of blister to form on my lip.
