8 Possible Jaw Lump Causes

The list below shows results from the use of our quiz by Buoy users who experienced jaw lump. This list does not constitute medical advice and may not accurately represent what you have.

Lymph node inflammation behind the ear

There are lymph nodes behind the ear. Lymph nodes are where your immune cells live, and when they become enlarged, it could be from a nearby infection, immune response, or even backlog of blood.

Rarity: Common

Top Symptoms: pain behind the ear, swelling behind the ears

Symptoms that always occur with lymph node inflammation behind the ear: swelling behind the ears

Urgency: Primary care doctor

Mononucleosis infection

Infectious mononucleosis, also called "mono" or "kissing disease," can be debilitating for a while but is usually not dangerous in itself.

Several viruses cause mononucleosis. It spreads easily through saliva and other body fluids. Sharing a drinking glass or a spoon, or kissing someone who has the virus – even they show no symptoms – will transmit the disease. It can also be sexually transmitted.

Due to lifestyle, teenagers and young adults seem to be the most susceptible.

Symptoms include tiredness, sore throat, fever, rash, body aches, swelling in the neck and armpits, and sometimes swollen liver and spleen. The symptoms alone are usually enough for the doctor to make a diagnosis.

Because mononucleosis is caused by a virus, antibiotics will not help. Treatment consists of bed rest, fluids, and good nutrition. The patient should still be under a doctor's care due to the risk of secondary infections or damage to the heart, liver, and spleen.

Handwashing, cleanliness, not sharing dishes or drinking glasses, and not having unprotected sex are the best ways to prevent mononucleosis.

Rarity: Common

Top Symptoms: fatigue, headache, loss of appetite, abdominal pain (stomach ache), cough

Urgency: Primary care doctor

Osteoma of skull and facial bones

An osteoma is a benign (non-cancerous) outgrowth of bone, usually in the skull and facial bones. They are slow growing and usually cause no symptoms. Osteomas are noticed once they begin causing problems with breathing, vision, or hearing.

Rarity: Rare

Top Symptoms: new headache, vision changes, steady headache, trouble swallowing, sinus pain

Urgency: Primary care doctor

Skin cyst

A cyst is a small sac or lump, filled with fluid, air, fat, or other material, that begins to grow somewhere in the body for no apparent reason. A skin cyst is one that forms just beneath the skin.

It's believed that skin cysts form around trapped keratin cells – the cells that form the relatively tough outer layer of the skin.

These cysts are not contagious.

Anyone can get a skin cyst, but they are most common in those who are over age 18, have acne, or have injured the skin.

Symptoms include the appearance of a small, rounded lump under the skin. Cysts are normally painless unless infected, when they will be reddened and sore and contain pus.

Diagnosis is made through physical examination. A small cyst can be left alone, though if it is unsightly or large enough to interfere with movement it can be removed in a simple procedure done in a doctor's office. An infected cyst must be treated so that the infection does not spread.

Rarity: Common

Top Symptoms: skin-colored armpit bump, marble sized armpit lump, small armpit lump

Symptoms that always occur with skin cyst: skin-colored armpit bump

Urgency: Wait and watch

Tooth abscess (infection)

A tooth abscess is a collection of infected material (pus) in the center of a tooth. It is due to bacterial infection.

Rarity: Uncommon

Top Symptoms: severe jaw or tooth pain, swollen jaw, jaw stiffness, tooth pain that gets worse with hot, cold, or sweet beverages, warm and red jaw swelling

Symptoms that always occur with tooth abscess (infection): severe jaw or tooth pain

Urgency: Primary care doctor

Overactive thyroid

The thyroid is a small, bow-tie shaped gland in your neck. Its main job is to produce thyroid hormone (known as T3 or T4), which serves a wide array of functions throughout the body.

When too much thyroid hormone is released, the body’s metabolism gets ramped up, causing symptoms ...
