I am a 25 yr. old female with healthy teeth/gums normally. I had my 3rd molars removed in 2004. The past yr or so, it seems that the gum tissue on the sites where my 3rd molars were has been sore. Almost like what a sore throat feels like. Now, underneath my tongue on the left side got very sore. I saw an oral surgeon and I could tell he was clueless and he supposed that it was a "salivary stone". Well, it went away and about 4 days later I get a "bump" inside my lower lip on the RIGHT side. It seems to have swollen and feels like a knot and is painful and stings when I eat. It feels like the whole right side of my inner bottom lip has little knots/nodules and it hurts. Also, I've had red striations of soreness under my tongue and today on the inside of my lower lip. I don't understand what it is and I'm not even a smoker or a drinker. It's not a blister, or doesn't feel like one. Today the right side underneath my tongue was hurting (the salivary gland) and the last two days my right lymph node under my jaw has been swollen and painful. Can anyone shed some light?
