Feeling many small lumps under the armpit

Feeling multiple small lumps under the armpit is usually caused by conditions such as eczema, folliculitis, or lymphadenitis. Treatment should be based on the specific diagnosis. Detailed explanations are as follows:

1. Eczema

Eczema is a common inflammatory skin condition, often associated with local skin moisture or exposure to allergens. Patients may develop red papules or vesicular papules on the skin surface, accompanied by symptoms such as itching, oozing, and stinging pain. In such cases, topical medications such as tacrolimus ointment or desonide cream should be used according to medical advice to relieve symptoms.

2. Folliculitis

Folliculitis is usually caused by bacterial infection due to poor local hygiene. It leads to firm, red bumps around hair follicles, accompanied by tenderness and mild itching. It is generally recommended that patients use topical antibiotics such as erythromycin ointment or mupirocin ointment as directed by a physician to improve symptoms.

3. Lymphadenitis

Lymphadenitis is typically caused by bacterial or viral infections. Local inflammatory stimulation can lead to lymph node swelling, presenting as single or multiple palpable lumps, accompanied by local pain, fever, and other symptoms. In such cases, patients should take oral medications such as azithromycin tablets or levofloxacin tablets under medical supervision.

In addition to the above common causes, other factors such as sebaceous cysts, fibromas, or localized tumors may also be responsible. Patients should seek timely medical evaluation and treatment to avoid delays in diagnosis and management.
