Armpit Pain: Causes, Symptoms & When to See a Doctor

Armpit pain can be caused by a variety of factors, including:

- Muscle strain or injury: Overusing the muscles in your armpit, such as during repetitive overhead activities, can cause a muscle strain or injury.

- Nerve damage: Damage to the nerves in your armpit, such as from a pinched nerve or brachial plexus injury, can cause pain.

- Skin conditions: Skin conditions that affect the armpit, such as eczema or psoriasis, can cause pain, itching, and burning.

- Infection: An infection in the armpit, such as a boil or abscess, can cause pain, swelling, and redness.

- Lymphadenopathy: Swollen lymph nodes in the armpit, which can occur due to infection, cancer, or other medical conditions, can cause pain.

- Breast conditions: Some breast conditions, such as mastitis (inflammation of the breast tissue) or breast cancer, can cause pain in the armpit.

- Other medical conditions: Certain medical conditions, such as heart disease, lung disease, or thyroid problems, can also cause armpit pain.

If you are experiencing armpit pain, it is important to see a doctor to determine the cause and receive appropriate treatment.
