  • Cerebrovascular Accident causes damage to some part of the brain, which can also lead to disturbance in the brain functioning, headaches or dizziness. The nerve endings of the axilla can also be damaged and cause pain in axilla or axillary pain which is similar to an electric current.
  • Diabetes, if ignored and not treated properly, leads to increased levels of blood sugar in the body which in turn leads to peripheral neuropathy where the excessive glucose damages the small blood vessels and nerves resulting in pain in different regions including the armpit area.
  • Cysts tend to develop easily in the underarm area, as this region is moist, dark and warm which makes it an ideal place for formation of sacs of fluid and debris. However, majority of the times, these cysts are harmless and are a method of getting rid of toxins. Nevertheless, cysts can cause severe pain in axilla or axillary pain. For this reason among other, cysts in the axilla should never be ignored and they need immediate medical attention as they could be an early indication of cancer.
  • Hyperthyroidism is a condition where the thyroid gland is overactive. This causes swelling of the glands in the axilla and pain.

Some of the causes for this include heat, bad hygiene, and excessive sweating. All these will cause formation of boils, hardened patch of skin with blunt, radiating pain.
  • Peripheral Artery Disease is the obstruction of arteries present close to the heart or brain and which travel through the arms and legs. When there is any interference in the flow of blood near the axilla or shoulder, then patient may experience a sharp pain radiating from underarm to the shoulder.
  • Lymphadenitis is infection of the lymph nodes or glands and can occur as a result of complication of bacterial infections. There is enlargement, inflammation and swelling of the lymph nodes. This occurs due to a reaction to viruses, fungi, or bacteria. Lymphadenitis can also cause axillary pain along with tender, hard and swollen lymph nodes.
  • Shoulder Dislocation occurs when the top most portion of the upper arm’s bone has partially or completely moved out from the shoulder socket. This causes pain and discomfort in the axilla as well as the shoulder.
