Hi, in the last month, I have these small, flesh-colored/maybe somewhat white painless bumps on my inner bottom lip. I noticed that today they may have began to go up to the top inner lip, but I am not sure. Do you know what these are? I also have two bumps on the corners of the inside of my mouth, one of them is kind of sore because I ve been chewing on it, and the other one is completely painless and barely noticeable. Help?
