What does a knot below jaw line indicate?
Patient: About 3 months ago I had a bad toothache (my left side back tooth) I went to the dentist because I.wanted them to pull it but they wanted to do a root canal and then cap it. I did not have the money for all of that so they gave me antibiotics and pain medicine. I finished the antibiotics and my tooth quit hurting so I never went back to the dentist. About 3 weeks later I got a knot right below my jaw line it's about the size of a quarter and is very sensitive to touch. Is this an infection or something else? Doctor: Thanks for your query, I have gone through your query.The knot you are describing can be because of the tooth infection resulting in the formation of a cyst or osteomyelitis. So consult a oral physician and get a radiograph done to confirm the diagnosis. But get the tooth treated as early as possible. Once the infection is treated the lump or knot will automatically reduce.I hope my answer will help you, take care.
