Can a pimple after being popped cause minor mucous glands to make a cyst-like bump? I woke up one morning to go to work and everything was completely fine. I would say about 3 hours of me working, I notice I have a tiny, tiny bump on my lip. I thought it was a pimple so I popped it. Well it got bigger and then I have a habit of chewing on the inside of my mouth/lips and this is what my mouth looks like now! Please help. It does not hurt nor itch or anything, it's just big and annoying to look at. It's red because I was trying to pop the bump again. What can I do?
