Introduction

1. Mammary gland hyperplasia: This condition is commonly seen in female patients; the incidence of mammary gland hyperplasia is significantly higher in women than in men. 2. Cold exposure: Prolonged exposure to cold temperatures can also cause axillary pain. 3. Neuritis: Pain is typically described as burning or stabbing in nature and occurs intermittently.

Pain sensations generated by our bodies are, in fact, highly diverse based on subjective perception. For instance, some women may experience a sharp, stabbing pain under the arm—akin to being pricked by a needle. So, what causes axillary (underarm) pain? Below, we address this question.

What Causes Axillary Pain?

1. Mammary Gland Hyperplasia (Benign Breast Hyperplasia)

This condition is predominantly observed in women; the incidence of mammary gland hyperplasia is significantly higher among females than males. When axillary pain arises from mammary gland hyperplasia, it typically manifests as either a dull, distending pain or a sharp, stabbing sensation—and may extend to involve one or both breasts. In more severe cases, the affected area becomes tender to touch and may significantly impair daily life and work performance.

2. Exposure to Cold

Prolonged exposure to cold temperatures can likewise trigger axillary pain. Clinically, axillary pain is frequently attributed to cold-induced impairment of circulation. Additionally, excessive physical strain may contribute. As stated in traditional Chinese medicine: “Where there is pain, there is obstruction; where there is free flow, there is no pain.” Thus, stagnation of Qi and blood stasis constitute another primary underlying cause of axillary pain. Individuals susceptible to such conditions must prioritize basic thermal protection in daily life.

3. Neuritis

Neuritis is often a principal cause of axillary pain. Extensive clinical research indicates that most patients with neuritis have a history of recent immunization or exposure to cold prior to symptom onset. Young adults are particularly prone to developing neuritis. Early-stage symptoms commonly include unilateral pain localized to the root of the neck, supraclavicular fossa, or shoulder region. The pain is typically described as burning or stabbing in quality and tends to occur intermittently.

The above outlines the main causes of axillary pain. We hope this information proves helpful to you.

Redness and pain in the armpit

Axillary pain and redness may result from skin irritation caused by hair regrowth after underarm hair removal, which is a normal physiological phenomenon. On the other hand, conditions such as herpes zoster, folliculitis, or infected sebaceous cysts can also cause symptoms of pain and redness in the armpit. It is generally recommended to promptly visit a hospital for necessary examinations and early treatment to prevent disease progression and prolonged illness.
