I've been getting this red itchy bump under my Lower lip after I eat and it's like a bug bite but it's winter right now so theirs no bugs out. Although, I don't know what to do and it's worrying me, after consulting with my mom and Dad they didn't know what it was. It goes away after like an hour or two but then it comes back. It's like a tingling itchy feeling and it's red and theirs a bump. Please help me figure out what this is.
