There's a hard lump under the earlobe that hurts when touched. What medication should I take?

Under normal circumstances, a hard lump appearing beneath the earlobe that is painful upon touch may be related to factors such as trauma, acne, sebaceous cysts, folliculitis, or swollen lymph nodes. Patients are advised to take medication according to medical instructions for symptomatic treatment. Specific analyses are as follows:

1. Trauma

Trauma to the earlobe or inflammatory reactions from ear piercing can lead to the formation of scar tissue (keloids). Since numerous lymph nodes are distributed within the earlobe, inflammation around the ear—such as from external ear injuries—can trigger lymph node inflammation and swelling, resulting in a hard lump and causing the aforementioned symptoms. Treatment may include medications such as amoxicillin-clavulanate potassium dispersible tablets or cefalexin capsules, used as directed by a physician.

2. Acne

Poor personal hygiene may lead to infection of hair follicles below the earlobe by *Propionibacterium acnes*, potentially causing local skin symptoms such as pimples and pain. In severe cases, pustules may develop, affecting overall health. Patients may use medications such as doxycycline hydrochloride tablets or minocycline hydrochloride tablets under medical guidance.

3. Sebaceous Cyst

A painful hard lump beneath the earlobe might also be associated with a sebaceous cyst. When the follicular opening on the earlobe skin becomes blocked, secretions cannot be expelled, leading to cyst formation. It is recommended to take anti-inflammatory medications such as azithromycin tablets or amoxicillin capsules orally under a doctor’s supervision.

4. Folliculitis

Folliculitis usually results from an infection affecting the hair follicles of the ear, causing pain along with redness and swelling, which may produce the symptoms described above. Patients may be treated with medications such as cefuroxime axetil granules or doxycycline hydrochloride tablets as prescribed.

5. Lymph Node Enlargement

The cause is often complex, typically due to bacterial or viral infections. It commonly manifests as firm, swollen lymph nodes below or behind the ear, accompanied by tenderness upon pressure. Anti-inflammatory medications such as Niuhuang Jiedu Tablets or cefalexin capsules may be taken under medical advice.

All medications should be used only under the guidance of a healthcare professional. Patients must not self-medicate, to avoid adverse reactions.
