Lumps behind the ear may be caused by many things. They are rarely serious, but you may need to see a doctor to determine the origin. Treatment will depend on the cause and may include antibiotics or topical creams.
In most cases, lumps or nodules behind the ears are harmless. They may signal a need for medication, as in the case of an infection, but they are rarely a sign of a dangerous or life threatening problem.
Lumps can vary in size but are generally small- to medium-sized bumps, which may occur anywhere on the back of the ear and can be either hard or soft. In some cases, these lumps might be painful or tender, while other bumps cause little to no pain.
Several conditions may lead to knots, lumps, bumps, or nodules behind your ears. In order of likelihood, these conditions are:
- otitis media
- lymphadenopathy, or swollen lymph nodes (secondary to ear or throat infections)
- sebaceous cysts
- acne vulgaris
Many bacterial and viral infections can cause swelling in and around your neck and face. Two such infections are strep throat and infectious mononucleosis (caused by the Epstein-Barr virus). Other conditions can also cause swelling in and around the neck and face. They include:
This infection develops in the bony protrusion behind the ear, which is called the mastoid. It may cause pus-filled cysts to develop. In turn, you may feel those as lumps or knots behind your ear.
An abscess develops when tissue or cells in an area of the body become infected. Your body responds to the infection by trying to kill off the invading bacteria or virus. To fight the bacteria, your body sends white blood cells to the infected areas.
These white blood cells begin gathering in the damaged location, and as a result, pus begins to develop. Pus is a thick, fluid-like product that develops from dead white bloods cells, tissue, bacteria, and other invading substances. Abscesses are often painful and warm to the touch.
Otitis media is another term for an ear infection. These can be bacterial or viral. When an infection occurs, it can cause painful fluid buildup and swelling. These symptoms may
Lymphadenopathy (secondary to ear or throat infections)

Acne is a common skin condition that occurs when hair follicles in the skin become clogged. Dead skin cells and oil can clog the follicles, and then pimples and bumps may develop. In certain cases, these bumps will grow to be large, solid, and sometimes painful.
Lipomas are not always detectable from the skin’s surface, but as they grow larger, it’s more likely that you’ll be able to feel them with your hand.
Identifying lumps behind the ears
If you have a history of acne, it may be easy for you to diagnose a lump or bump behind your ear as a pimple. But for other people, figuring out what’s causing the raised area may be trickier.
How to self-check
Your hand is your best tool for detecting lumps or bumps behind your ears. Below are a few questions you can ask yourself:
- Does the lump feel soft and pliable? If so, it’s probably a lipoma.
- Is the spot tender and painful, especially when touched? Then it could be a pimple or an abscess.
- In addition to the bump, are you experiencing other symptoms? Other symptoms could include fever or chills. If so, the lump could be another sign of an infection.
When to see a doctor
If the lump is problematic, causing you pain or discomfort, or associated with other symptoms, make an appointment with your doctor. You can connect to a physician in your area using the Healthline FindCare tool.
A quick physical inspection of the area and a general checkup can usually help your doctor figure out exactly what is happening behind your ear.
