Overview
A lump behind the ear can be concerning. In some cases, they can indicate something serious like cancer. Lumps are usually non-cancerous and can be due to a swollen lymph node.

This swelling often results from infections, illnesses, or injuries and can indicate a more serious underlying condition. If your lymph nodes are swollen, it may be due to:
- Cold: The common cold is a frequent benign cause of swollen lymph nodes, but it can also stem from viral or bacterial infections. Lymphadenopathy, or swollen lymph nodes, typically resolves once the infection clears.
- Ear infection: Ear infections trigger your body’s immune response, leading to white blood cells accumulating in the area. This can result in swollen lymph nodes, and treating the ear infection is crucial for resolving the lump.
- Eye infection: Similar to ear infections, eye infections can cause nearby lymph nodes to swell. Addressing the eye infection is vital to reducing the lump behind your ear.

- Sinus infection: Sinus infections often lead to swollen lymph nodes in the head and neck, potentially causing a lump behind your ear.
- Infected tooth: Dental infections can also result in swollen lymph nodes in the neck region, contributing to a lump behind the ear. Don’t ignore dental health—seek treatment if you suspect an infection.
- Skin infection: Boils, abscesses, or skin infections caused by bacteria like streptococcus and staphylococcus can lead to lymphadenitis, resulting in swelling of the linked lymph nodes.
- Gingivitis: Untreated gingivitis can spread to nearby tissues, causing periodontal disease and swollen lymph nodes, which may lead to a lump behind the ear. Therefore, don’t ignore dental hygiene.
- Cat scratch fever: This infectious illness, caused by cat scratches, can lead to chronic lymph node swelling, resulting in lumps behind the ear or other body areas.
- Mouth sores: Canker sores or abscesses in the mouth can also lead to swollen lymph nodes, contributing to a lump behind your ear.

2. Other infections
- Strep throat: This bacterial infection often results in swollen, painful lymph nodes in the neck, which may extend to the area behind the ear. Timely antibiotic treatment is a must to avoid the risk of complications.

- Blood tests
- A biopsy to examine tissue from the lump
- Computed tomography (CT) scan to get a detailed view of the area

- When checking your neck, tilt your head towards the side you’re examining to help relax the muscles.
- Use your fingers to press gently under the muscle to detect any swelling.
- When checking above the collarbone, hunch your shoulder and bring your elbows forward to relax the skin and make the check more accurate.
By conducting this self-check, you can monitor any changes and identify when to seek medical advice.

How to treat a lump behind the ear?
Based on the diagnosis, your doctor will recommend the most appropriate treatment plan. Here’s what your visit might look like and the possible treatment options:
1. Antibiotic treatment
If a bacterial infection causes the lump, your doctor may prescribe antibiotics. These medications help to clear the infection, reducing the size of the lump and relieving any associated discomfort.
2. Surgical drainage
In cases where the lump is due to an ear infection or a sebaceous cyst, your doctor may recommend drainage. This is a minor procedure where fluid or pus is drained from the lump to alleviate pressure and promote healing.
3. Surgery
For certain lumps, such as lipomas (harmless fatty growths), cysts, or tumors, surgical removal may be necessary. Your doctor will discuss the procedure with you, outlining how it will be performed and what to expect during recovery.
4. Prescription medications
Depending on the nature of the lump, your doctor may also prescribe antiviral medication if the cause is viral or stronger pain relievers if needed to manage discomfort.
5. Over-the-counter medications
After your visit, your doctor might suggest some at-home or over-the-counter (OTC) treatments to manage mild symptoms. For mild discomfort, your doctor may recommend pain relievers like acetaminophen, ibuprofen, or aspirin. These can help reduce pain and inflammation while you’re undergoing other treatments.
If symptoms persist or worsen, a follow-up visit may be required to eliminate the chances of remission.
How to prevent swollen lymph nodes behind the ear?
Swollen lymph can easily be prevented by applying a warm compress over the affected glands under the ear. A washcloth can be dipped in hot water and used gently for 5-10 minutes on or under the affected earlobe.
Other than warm compress, NSAIDs like acetaminophen (Tylenol) and Ibuprofen (Advil) can be taken over the counter for immediate pain relief. Practicing good hygiene and keeping ears clean reduces the risk of infections that can cause swollen lymph nodes.
Minimizing exposure to infections and individuals suffering from those will help lower the chances of developing swollen lymph nodes.
Staying up-to-date with vaccinations and maintaining a healthy lifestyle will boost your immune system. By getting vaccinated and practicing a balanced diet, regular exercise, and stress management, you can support overall health and reduce the risk of infections like swollen lymph nodes and others.
When to Consult a Doctor
Many different reasons can cause a lump behind the ear. Don’t waste time worrying. Consult a doctor immediately when you notice it to rule out the possibility of anything serious.
FAQs about swollen lymph nodes
In most cases, the swelling subsides in a few days to weeks. However, if it persists beyond that, an evaluation is usually required.
If the swelling and swollen lymph node is persistent and stays for more than one week, complex and untouchable, it depicts that the lymph node is severe and needs medical attention.
Cancerous lymph nodes start to appear like any other temporary lymph node. The only difference is no home remedy will work on it. It will persist longer and affect your overall health, e.g., lethargy and fatigue.
The cancerous lump behind the ear lobe will look like a pear-shaped yellow bump, growing gradually to a bigger size than usual. It will grow bigger to 5 cm and appear harder than average.
Symptoms of an infected lymph node include noticeable swelling and tenderness in the affected area. The lymph node may feel soft or appear matted together with surrounding nodes. The skin over the infected node may become red and inflamed, and in more severe cases, the node can fill with pus. Additionally, fluid may drain from the node onto the skin. If you experience these symptoms, it’s important to seek medical advice for appropriate diagnosis and treatment.
Most often, these lumps are due to non-cancerous causes, such as a swollen lymph node from an infection, a common cold, or a skin condition. However, in rare cases, a lump could be a tumor, which may be benign or, less commonly, cancerous. In either case, a doctor’s diagnosis is important.
Yes, it is normal for lymph nodes to swell on one side. This can happen when the immune system responds to a nearby infection, as the lymph nodes filter harmful substances like bacteria and viruses. The swelling is usually temporary and part of your body’s defense mechanism. However, if the swelling persists or is accompanied by pain, it’s important to seek medical advice for a proper diagnosis, as it may indicate a more serious condition.
