What causes a Lump on inside of mouth near lips?

Answer:
Well, this is a sore. It should look white, like somebody had a miniature nuclear war in your mouth, right? Yes. So, this happens wen you bite yourself when you eat too much junk food. Don't worry. A little chrysanthemum tea drink (Hong Kong Supermarket) will fix this problem.
