Usually there is no need to worry about swollen lumps or glands under the skin. A sore throat or cold can cause the swelling of the lymph nodes under your jaw, on either side of the neck or behind your ears.

Enlargement of the glands can be caused by serious infections too, making them tender and firm. Injuries like bites or cuts or tumors of the neck, mouth or head can also cause tenderness and swell the glands. The lumps might be painless or painful, firm or soft, multiple or single depending on their cause. They might remain the same size or grow too quickly.

What Causes Lump in My Jaw?

Lump in jaw that hurts

Making an appointment with and getting the opinion of an otolaryngologist or an ENT physician is the recommended course of action if the big or small lump on jaw is causing you pain. This pain might be originating from any of the various structures that lie under your jaw.

For instance, the neck contains hundreds of lymph nodes which are an important component of the immune system. Jugulodigastric lymph nodes are the big lymph nodes located on each side of the jaw and it is highly likely that the pain is being felt in them since they are known to swell up while the body is battling inflammation or infection. The swelling in these lymph nodes can also be caused because of a serious illness like cancer.

The submandibular gland is a saliva gland located underneath the jaw and is another of the structures that might cause pain and small lump under chin. The swelling and pain in this gland usually results from stones in the gland or various other processes. The ENT specialist will be better able to examine the jaw and give his/her opinion about the lump you have.

Lump in jaw that can move around

What if I have lump in my jaw that is capable of moving around? It is a common issue faced by many people during their childhood which remains with them even after they grow up. Usually if the lump is movable it means that it isn’t attached with another tissue and thus is nothing as serious as cancer. It might be a slightly large gland or a fatty tissue which is totally harmless. Such movable lumps can be caused due to injuries like fractured jaw and internal trauma which results in localized swelling. Movable lumps can also be noncancerous growths like a lipoma, a cyst or a cystic lesion caused because of acne.

Advice from Others Who Have Been There

I would get the lump on jaw checked by a doctor immediately. My dentist thought that the lump I had on my jawbone was because of an abscessed tooth but when I went to get it pulled out, it turned out to be a 4cm cancerous tumor. I was shocked to say the least as I had ignored it for a long time which turned out to be a big mistake. So, I suggest that you don’t make that mistake and get the lump checked out immediately. Another thing you must keep in mind is that I was a smoker, the cancer might be associated with it.

My mother freaked out when she saw a lump on her jaw but she had it checked out by a doctor. It turned out to be a TMJ issue and some fluid that got accumulated there. She had to take antibiotics and make use of a warm compress for some time to get if off. I hope that is the same for you.
