Lump behind, inside the ear canal, under or on the lobule

Unlike typical ear infections or earwax accumulation, a lump in the ear indicates an unusual growth or swelling that is noticeable to touch or sight. These lumps come in different sizes, shapes, and textures and can appear either on the outer ear or within the ear canal.
Common positions of ear lumps
Lumps can appear in various positions around the ear, each with distinct characteristics and potential causes:
Lump behind the ear
A lump behind the ear is commonly a swollen lymph node, which might indicate an infection or inflammation nearby. This type of lump can also be a lipoma, a benign fatty growth that usually poses no health risk but can be monitored for any changes.
Lump inside the ear canal
A lump inside the ear canal can be more concerning and is often related to ear infections or benign tumors like osteomas. These lumps can obstruct the ear canal, causing discomfort or hearing issues, and should be evaluated by a healthcare professional to determine the appropriate treatment.
Ear lump on the lobule
An ear lump on the lobule, or earlobe, is often associated with sebaceous cysts, which are non-cancerous bumps filled with a greasy substance called keratin. These cysts can develop due to blocked sebaceous glands or hair follicles. Another common cause for a lump on the earlobe is a keloid, which is an overgrowth of scar tissue from a piercing or injury.
Lump under the ear lobe
A lump under the ear lobe is typically a swollen lymph node or a cyst. Swollen lymph nodes in this area often result from infections in the head, neck, or respiratory tract. Cysts in this region, similar to those on the earlobe, are usually benign but should be checked for any signs of infection or changes in size and shape.
Lump on a pierced ear
A lump on the ear from piercing is a common issue that many individuals experience. This lump can develop around the pierced area on the ear and may vary in severity. Often, the lump is caused by an infection at the site of the piercing, known as a pierced ear infection lump. This can lead to swelling, redness, and tenderness. Sometimes, a lump around the ear piercing appears, which can be concerning due to its size and discomfort. A lump at the back of the ear piercing area or behind the ear piercing is also frequently noted. Such lumps may be attributed to the body's response to the piercing, where it forms a small lump on the back of the ear piercing as it heals. If you're experiencing a lump on a pierced ear, it's essential to keep the area clean and seek medical advice if the lump persists or worsens.

Pea-sized lump behind ear lobe with no pain
Discovering a pea-sized lump behind the earlobe that causes no pain can be concerning, but it is often benign. Such lumps can result from various conditions, including sebaceous cysts, which are non-cancerous bumps filled with keratin, or swollen lymph nodes reacting to an infection nearby. Lipomas, which are harmless fatty growths, could also present as small, painless lumps. While these lumps are generally not serious, it is advisable to monitor them for any changes in size, shape, or pain, and consult a healthcare professional for a thorough evaluation to rule out any underlying issues.
Painful pea-sized lump behind on the ear lobe
A painful, pea-sized lump behind the ear lobe could be due to various causes. These may include:
- Lymphadenopathy: Swollen lymph nodes due to an infection or inflammation in the nearby area
- Sebaceous cyst: A sac filled with keratin and oily fluid, which can become inflamed and painful
- Abscess: A localized collection of pus caused by a bacterial infection.
- Inflammatory skin conditions: Such as folliculitis or acne, which can cause painful bumps
- Trauma: Injury or trauma to the area, resulting in a lump
Sore, firm and hard lumps behind the ear
Sore, firm, and hard lumps can indicate various underlying conditions and have distinct characteristics:
- Sore lump: A sore lump is typically tender or painful to the touch. It may be caused by inflammation, infection, or injury. Common examples include swollen lymph nodes due to an infection or a sebaceous cyst that has become inflamed.
- Firm lump: A firm lump is solid to the touch and may not cause significant pain or discomfort. It can be caused by conditions such as fibroadenomas in the breast or lipomas, which are noncancerous growths of fat cells.
- Hard lump: A hard lump feels dense and rigid, often without much give when pressed. Hard lumps may raise concerns about the possibility of cancerous growths, such as malignant tumors. However, not all hard lumps are cancerous; they can also be caused by benign conditions like calcifications or fibrosis.
It's crucial to have any new or concerning lumps evaluated by a healthcare professional for proper diagnosis and management. Depending on the characteristics of the lump and associated symptoms, further testing such as imaging studies or biopsy may be necessary to determine the cause and appropriate treatment.
Why do I have a lump behind my ear? The causes
Ears can be impacted by various conditions that lead to lumps or abnormal growths. These conditions can generally be divided into two main categories: those related to infections and those that are not.
- Infection-related causes usually result from bacterial or fungal infections targeting specific parts of the ear. These infections often cause pain, swelling, and the formation of lumps.
- Non-infection-related causes arise from different factors, such as gland blockages, benign tumors, or the formation of scar tissue. Each of these conditions has its own distinct symptoms and treatment options. In this discussion, we explore these conditions to gain a better understanding of their characteristics and implications.
Otitis externa (Swimmer's ear)
Otitis media (Middle ear infection)
Mastoiditis (Infection of the mastoid bone)

Lipomas (benign tumors)
Keloids (excessive scar tissue)

Lump behind baby's ear: what to do
Discovering a lump behind an infant's ear can be concerning for parents. Commonly, a lump behind a newborn's ear might be due to swollen lymph nodes, which often occur as the baby's body responds to minor infections or immune system activity. These lumps are generally small, soft, and movable, and they typically resolve on their own as the underlying condition improves. However, if the lump behind an infant's ear persists, grows, or is accompanied by other symptoms such as fever or irritability, it's important to consult a pediatrician to rule out more serious conditions and ensure the baby's health and well-being.

How to get rid of a lump behind ear
Treatment options for infection-related lumps in the ear aim to alleviate discomfort and pain effectively. Depending on the severity and cause of the infection, several approaches can be considered:
- Antibiotics: Essential for bacterial ear infections, antibiotics like amoxicillin, ciprofloxacin, or azithromycin are commonly prescribed. Oral or intravenous administration may be necessary for severe cases. Completing the full antibiotic course as directed is crucial to prevent resistance
- Ear drops: Specifically formulated to target ear infections, ear drops often contain antibiotics or antifungal agents. Examples include neomycin-polymyxin B-hydrocortisone, which fights infection and reduces inflammation and pain. Proper administration involves cleaning the outer ear, tilting the head, and instilling the drops. Adherence to the prescribed treatment regimen is essential for optimal results
- Warm compresses: Applying warm compresses can relieve pain and swelling associated with ear infections. This involves applying a warm, damp washcloth to the affected ear for 10-15 minutes several times a day. Be cautious of the temperature to prevent burns
Treatment options for non-infection-related lumps in the ear aim to alleviate discomfort and address complications. These include:
- Surgical removal: For significant discomfort or hearing impact, lumps may be surgically removed under anesthesia. Post-surgery care and follow-ups ensure proper healing and reduce risks
- Corticosteroid injections: These injections reduce inflammation and inhibit abnormal tissue growth, useful for keloids or scars. Multiple sessions might be needed, with potential side effects like skin discoloration
- Laser therapy: Non-invasive laser therapy breaks down abnormal tissue, suitable for conditions like hemangiomas. Effectiveness varies, with multiple sessions often required
- Radiation therapy: Targeting and destroying cancer cells, radiation therapy is used for cancerous lumps, administered externally or internally depending on the cancer type and stage
