Hello! My daughter is 17 and has been complaining about a pain in her mouth. She has a pea size lump on the floor of her mouth under her tongue which is kind of white and she has had this for years. Today is the first day she complained about pain while she was chewing. She says it's mild and on occasion spreads to the ear on the side where this lump is. Not to mention, one of her tonsils has been swollen since February and every time the pain comes back and I take her for a strep test it comes back negative(February was the last time she had strep). She also claims her lymph nodes are swollen but there is only so much I can believe Should I be worried about this lump?
