What Could Be the Reason of Lump Under the Chin?

Q: I’m 24 years old female. I have a hard lump directly under my chin, not in my throat. I have had an itchy throat and have always has a lot of phlegm. I noticed the lump three days ago. My sister has had two benign tumors removed from her throat in the last 3 years. I don’t know if this is important information but I thought it would be helpful. I don’t have any other symptoms besides scratchy throat phlegm and hard lump. The lump does not hurt. Do you think this is just an infection or should I take it more seriously?

This is the location of the submental group of lymph nodes. The commonest cause of having such lymph nodes is any chronic (persistent) infection.

Our face has  a lot of blood and lymph supply. So, any source of infection in or around the face may lead to the enlargement of these lymph nodes.

Common Causes

These causes would include:

  • Tooth decay
  • Swollen/ infected gums
  • Throat infection
  • Sinusitis
  • Viral infections like, mononucleosis, Epstein-Barr virus and cytomegalovirus in the past.
  • Any autoimmune pathology in the body, like lupus or rheumatoid arthritis. Here, other symptoms suggestive of these conditions would also be present.

It would be advisable to first rule out any of these infections as the source of lymph node enlargement.

Since you are having throat secretions, get appropriate treatment for this infection first. These glands should subside with treatment.

Recognizing Tumorous Lymph Nodes

Tumor glands would become hard with time and get somewhat attached to the underlying structures. If you try to move them, the movement would be restricted.

They are usually not painful. Read in details about such lumps.

Though more likely it appears to have an infective reason, you need to be observant about the swollen glands. If you observe them getting bigger, harder or painful, it would be good to see a doctor.

Take Care,

    Hello, 2 nights ago I noticed that it felt sore above my front tooth when I brushed my teeth before bed. I didn’t really think anything of it until I brushed my teeth again yesterday morning. I looked closely in the mirror and I could see a little cut in my gums along with a bunch of tiny little puncture type cuts. I am assuming it’s from my toothbrush bristles. I didn’t brush my teeth any more yesterday but I rinsed my mouth out with peroxil instead. When I woke up this morning the palate behind my two front teeth on top feels really swollen. My gums are puffy in the front around my front teeth and my teeth feel sore when I bite down. Is this normal with a healing oral wound?
    please help

      These may be swollen lymph nodes. Like some people have a tendency to get swollen tonsils, your submental (under the chin) lymph nodes may be swollen.

      They swell up whenever they catch an infective germ. As the infection weans off, they may regress in size.

          Yes, very likely to be.

          Apart from this, just check up if there’s any decaying tooth/ infected tooth in your mouth. That can also be a source of bloody sputum.
