Swollen Lymph Nodes in the Neck: Causes, Symptoms, and Care
Noticing a lump in your neck or under your jaw can feel alarming, especially when it appears suddenly or feels sore to the touch. In many cases, swollen lymph nodes in the neck are a sign that your immune system is responding to an infection, irritation, or inflammation.
Swelling that lasts, worsens, or appears with other symptoms should be evaluated. ENT Carolina helps patients in Gastonia, Shelby, Belmont, and surrounding North Carolina communities understand throat and neck concerns and decide what care may be needed.

What Are Swollen Lymph Nodes?
Lymph nodes are small glands that help filter fluid and support your body’s immune response. They are part of the lymphatic system, which helps your body fight germs and manage fluid.
When lymph nodes enlarge, patients often describe them as swollen glands, knots, lumps, or tender bumps in the neck.
Why Lymph Nodes Swell
Lymph nodes often swell when immune cells collect in response to something nearby. Common issues we see in the office include a sore throat, sinus infection, ear infection, dental problem, skin irritation, or mouth sore.
A swollen lymph node does not automatically mean something serious. Tender swelling that comes on quickly is often related to infection. A lump that is hard, painless, fixed in place, or continuing to grow should be checked.
Common Areas Affected
When people think about lymph nodes, they often are familiar with common trouble spots such as under the ears, but there are several other lymph nodes that can also become irritated. In the head and neck area, swelling may appear:
- Under the jaw or chin
- On either side of the neck
- Behind the ears
- Along the back of the neck
- Near the collarbone
A swollen lymph node under the jaw, also know as submandibular lymph nodes, can become enlarged when the body is fighting an infection or inflammation in the mouth, through, teeth, or nearby areas.
Common Causes of Swollen Lymph Nodes in the Neck
There are many possible causes of swollen lymph nodes in the neck. The location of the swelling, how long it has been there, and your other symptoms can help guide the next step.
Infections
Infections are among the most common causes of swollen lymph nodes. Neck or jaw lymph nodes may enlarge with:
- Cold or flu-like illness
- Sore throat or tonsillitis
- Strep throat
- Ear infection
- Sinus infection
- Dental infection or gum inflammation
- Mouth sores
- Skin infection near the head or neck
A neck lymph node infection may cause swelling, tenderness, warmth, or redness over the area.
Viral vs. Bacterial
Viral and bacterial infections can both cause swollen lymph nodes, but they are treated differently.
Many sore throats are caused by viruses and do not need antibiotics. Viral symptoms may include cough, congestion, hoarseness, or a runny nose.
Bacterial infections, such as strep throat, may cause sudden throat pain, fever, painful swallowing, swollen tonsils, or swollen lymph nodes in the front of the neck. Testing may be needed before antibiotics are recommended.
Less Common Causes
Less common causes of swollen lymph nodes include inflammatory conditions, certain medications, salivary gland problems, infections, or benign growths.
Because lymph nodes respond to many different changes in the body, ongoing swelling does not automatically mean something serious. However, lymph nodes that keep getting larger, do not improve, or appear with other concerning symptoms should be checked by a healthcare provider.
Can Swollen Lymph Nodes Be a Sign of Cancer?
Most swollen lymph nodes are not an indication of cancer. In less common cases, persistent swelling in the neck may be related to lymphoma or cancers that begin in nearby areas, such as the mouth, throat, thyroid, or salivary glands. Painless lymph node swelling, especially when paired with other symptoms such as weight loss, fever, or night sweats, is an indication that you should be evaluated.
Symptoms Associated With Swollen Lymph Nodes
Swollen lymph nodes may appear by themselves or with other symptoms. The overall pattern often matters more than one symptom alone.
Tenderness or Pain in the Neck
Tender lymph nodes may feel sore when pressed or when you move your neck. This often happens when your body is responding to infection or inflammation.
Lumps or Swelling
Some lumps feel soft and movable, while others may feel firmer. Try not to keep pressing on the area, since that can increase irritation and make it harder to tell whether the swelling is changing.
Fever and Fatigue
Fever, chills, body aches, or fatigue may point to an infection. Mono, for example, can cause fatigue, sore throat, and swollen lymph glands.
Sore Throat or Difficulty Swallowing
Because throat infections can trigger swollen neck nodes, you may also notice throat pain, tonsil swelling, hoarseness, postnasal drip, or ear pressure.
ENT Carolina evaluates throat and neck disorders, including persistent sore throat, recurrent tonsillitis in adults and children, neck lumps, salivary gland concerns, thyroid disorders, and swallowing-related symptoms.
Persistent or Worsening Swelling
A lymph node may stay enlarged for a short time after an illness. But swelling that lasts several weeks, keeps growing, or appears without a clear reason should be checked.
When Should You See an ENT Specialist?
Knowing when to see a doctor for swollen lymph nodes can be confusing. Consider an ENT evaluation if you have:
- Swelling that lasts more than a few weeks
- A lump that is growing
- A hard, fixed, or painless lump
- Recurrent swelling in the same area
- Swelling with trouble swallowing
- Redness, warmth, or significant tenderness
ENT Carolina offers care at locations in Gastonia, Shelby, and Belmont.
What to Expect At Your Visit
How Swollen Lymph Nodes Are Diagnosed
Diagnosis usually starts with a physical exam and questions about your symptoms. Your provider may ask when the swelling started, whether it is changing, if it hurts, your current relationship with tobacco and alcohol, and whether you recently had a sore throat, ear infection, dental issue, skin infection, or fever.
Your ENT provider may examine your ears, nose, throat, mouth, jaw, and neck. Depending on your symptoms, additional testing may be recommended. This may include blood work, imaging, or, in some cases, a biopsy. Evaluation may include imaging or lab tests when the cause is not clear.
Treatment Options for Swollen Lymph Nodes
Treatment depends on the cause of the swelling.
If a viral infection is likely, care may focus on symptom relief while your body recovers. Warm compresses, fluids, rest, and over-the-counter pain relievers may help with discomfort when appropriate.
If a bacterial infection is confirmed or strongly suspected, antibiotics may be prescribed. If the swelling is related to a dental issue, skin infection, salivary gland problem, or throat condition, treatment will focus on that source. Depending on your condition, you may be referred to a different specialist for treatment if it does not fall within the scope of our providers.
Why Choose an ENT Specialist for Evaluation?
An ENT specialist focuses on conditions affecting the ears, nose, throat, head, and neck. That can be especially helpful when swollen lymph nodes are connected to sore throat, tonsil problems, ear pain, sinus symptoms, salivary gland swelling, swallowing trouble, or a neck mass.
ENT Carolina’s providers care for adults and children with ENT concerns across Gastonia, Shelby, Belmont, and across the Carolinas. If your symptoms are persistent, worsening, or worrying you, an evaluation can help clarify what may be causing the swelling and what next steps make sense.
