Two days ago I noticed a small lump under my chin. It wasn't hurting that much when I first discovered it. Now, today it's extremely painful especially when I touch it or even yawn. It doesn't seem to have gotten any bigger from when I first noticed it. A few months ago, I noticed a growth under my tongue. It looked as if I had grown another tongue under it. It had become inflamed at one point. It lasted for about 3 weeks then did disappeared. Could this lump be in connection with the growth I once had?
