question: About 10 days ago I noticed a lump Right under my jaw at the bottom of my earlobe it was sore and tender and occurred the day after I had my teeth cleaned at my dentist. The doctor gave me an antibiotic and it went away but now about a week later I have a larger piece of skin looks like skin tag on the back of my tongue. It wasn t there yesterday and seems to have popped up overnight Should I be worried Could this be related ?
