Introduction

Numerous small lumps felt under the armpit may be caused by folliculitis, swollen lymph nodes, sebaceous cysts, or other reasons, and targeted treatment should be provided according to the specific cause. In addition to these relatively common causes, other possibilities include epidermal cysts, lipomas, and fibromas. If any discomfort symptoms occur, it is important to seek medical attention promptly for evaluation and timely treatment to avoid delaying the condition.

Feeling multiple small lumps under the armpit may be caused by folliculitis, swollen lymph nodes, sebaceous cysts, or other conditions, and treatment should be tailored according to the specific cause. Detailed analysis is as follows:

1. Folliculitis

If local hygiene is neglected, hair follicles in the armpit may become infected, leading to folliculitis. Inflammatory stimulation can result in small, grain-sized papules, which may also be accompanied by itching. Medications such as erythromycin ointment or mupirocin ointment may be used as directed by a physician to relieve symptoms.

2. Swollen Lymph Nodes

If tissues near the armpit become inflamed, inflammatory factors can trigger lymph node swelling, causing the sensation of multiple small lumps upon touch. Under medical guidance, medications such as amoxicillin capsules or azithromycin tablets may help alleviate the condition.

3. Sebaceous Cyst

A sebaceous cyst forms when the excretory duct of a sebaceous gland becomes blocked, causing the cystic epithelium to expand due to accumulating contents, resulting in a retention cyst. This condition can also present with the aforementioned symptoms. Surgical removal is an effective treatment option.

Besides the above relatively common causes, other possibilities include epidermal cysts, lipomas, fibromas, etc. If any discomfort occurs, prompt medical evaluation and timely treatment are recommended to avoid delaying diagnosis and management.

Will the armpits still sweat after surgery for palmar hyperhidrosis?

The surgery for palmar hyperhidrosis primarily targets excessive hand sweating by interrupting specific segments of the thoracic sympathetic nerves to reduce sweat gland secretion. However, since the axillary sweat glands are innervated by different nerves, the procedure does not directly affect their function; therefore, sweating in the underarms may remain unchanged after surgery. Some patients may develop compensatory hyperhidrosis postoperatively, characterized by increased sweating in areas such as the armpits and back following a reduction in palm sweating.
