A small lump appears behind the ear?


Yesterday, my daughter suddenly developed a small lump behind her ear.
Then, she started to have a fever in the middle of the night.
I gave her fever-reducing medication, but she keeps saying she feels dizzy and can't get up.
She has been sleeping a lot.
What could this situation be? Is the lump causing the fever? Thank you, doctor.

When a lump appears behind the ear, especially in a child, it can be concerning for parents. The symptoms you've described—fever, dizziness, and lethargy—can indeed be related to the lump, but they may also indicate a separate underlying issue.
The lump behind the ear could be a swollen lymph node, which is a common response to infection. Lymph nodes are part of the immune system and can swell when the body is fighting off an infection, whether it be viral or bacterial. In children, this can often be due to common illnesses such as ear infections, upper respiratory infections, or even skin infections.
Given that your daughter has developed a fever and is experiencing dizziness and excessive sleepiness, it is essential to consider the possibility of an infection. The fever suggests that her body is responding to an infection, which could be localized (such as an ear infection) or systemic (such as a viral illness). The lump itself may be a sign of an infection in the area, or it could be a reaction to an infection elsewhere in the body.

Infections of the ear, such as otitis media (middle ear infection), can cause swelling of the lymph nodes behind the ear. Additionally, conditions like mastoiditis, which is an infection of the mastoid bone located just behind the ear, can also lead to swelling and fever. This condition is more serious and requires prompt medical attention.

The dizziness and lethargy you're observing could be due to several factors. If the infection is affecting her balance or if she is experiencing significant discomfort, it could lead to feelings of dizziness. Additionally, fever can cause fatigue and lethargy as the body uses energy to fight off the infection.

Given these symptoms, it is crucial to seek medical attention as soon as possible. A healthcare provider will be able to perform a thorough examination, which may include checking her ears, throat, and lymph nodes. They may also order blood tests or imaging studies if necessary to determine the cause of the lump and associated symptoms.

In the meantime, continue to monitor her symptoms. Ensure she stays hydrated and comfortable. If her fever persists or worsens, or if she shows any signs of distress, such as difficulty breathing, severe headache, or confusion, seek emergency medical care immediately.

In summary, the lump behind your daughter's ear, combined with her fever and other symptoms, could indicate an infection that requires medical evaluation. Prompt attention is essential to ensure she receives the appropriate treatment and to prevent any potential complications.
