A hard pimple grew under the female armpit

If a woman has a hard lump under her armpit, it may be due to local lymph node enlargement. If a subcutaneous sebaceous cyst appears, there may be slight pain when pressing with the hand, which requires examination and diagnosis.

1. Swollen lymph nodes: Lymph nodes are relatively important tissues in the human body and can be found in many locations throughout the body. If there is a local inflammatory reaction, such as bacterial or viral infection, it may cause swollen lymph nodes and symptoms of pain. The pain will be particularly obvious when pressed with the hands. There is a certain relationship between swollen lymph nodes and decreased resistance. Some people have malignant tumor cells in the armpits, which are transferred to the lymph nodes in the armpits through the lymphatic system, affecting the skin morphology and physical health of the armpit area.

2. Sebaceous cyst: Sebaceous cyst is a relatively common cyst. It is usually a symptom of blockage in the excretory duct of the sebaceous gland, which leads to a gradual increase in the sebaceous cystic epithelium. It usually gets blocked in the sebaceous gland, causing the contents to swell. Later, it can slowly form a retention cyst, but the growth rate is relatively slow. It is a relatively common benign lesion that can occur at different ages. There may be slight discomfort in the armpit area when pressing with your hands, but it is not particularly obvious, and the cyst is relatively hard.
