Is it normal to have pimples under your armpits?

When there are peanut-sized lumps under the armpits, it is mostly caused by inflammation in the human body, which causes swelling of the lymph nodes under the armpits. Just take some anti-inflammatory drugs at this time to easily eliminate this pimple and lump. Lumps under the armpits may also be a manifestation of some other diseases. If the lumps continue to grow and are accompanied by severe pain, you need to seek medical attention immediately.

1. Sebaceous cyst (commonly known as cyst)

It is located shallowly under the skin, with clear boundaries from the surrounding tissues. Small black depressions can be found on the local skin surface. It is generally painless, but may cause redness, swelling and pain when inflamed. Treatment: Surgical resection is recommended.

2. Lipoma

It is located in the subcutaneous fat layer, has clear boundaries, is soft, and is painless. It generally does not become infected. If there is no growth or pain, it can be left untreated. If treatment is required, surgical resection is the main approach, and there is no effective drug to control its growth.

3. Swollen lymph nodes

Taking the age of 40 as an example, most patients suffer from inflammation, and trauma to surrounding tissues may occur. If it is not painful, fixed, and hard, you should pay attention to a tumor (which is less common).

4. Accessory mammary gland

Some women may have accessory breasts, which are characterized by unclear boundaries, soft masses, and are often bilateral. Some patients may experience distension and pain during menstruation.

Lumps under the armpits may cause the above diseases. No matter which disease it is, we must treat it in time, especially in the case of tumors. If not treated in time, the condition will worsen, which will affect the patient's health. In addition, experts remind that early treatment will be more effective.
