Pain in Armpit

Arms | Rheumatology | Pain in Armpit (Symptom)


Description

The armpit, which is medically referred to as axilla or axillary cavity, is quite prone to developing infections. Boils, rashes and skin infections are more likely to develop in this area as bacteria can easily flourish in the warm and moist skin folds. Moreover, the skin in this area is thinner and is therefore more sensitive.

Pain under the armpit may also be accompanied with changes in the colour and texture of the skin. Pain in the armpit may even radiate to the shoulder and the arm. Soreness in the armpit is usually indicative of a pathogenic infection, but underarm pain could even be caused due to other medical conditions.

Causes

Pain in the armpit could be something simple like a pulled muscle or pinched nerve. However, it could also indicate a more serious medical condition. Since the skin in this region is more sensitive, it can easily get affected on coming in contact with harsh substances present in deodorants, antiperspirants or hair removal products.

Bacteria can enter through cuts or breaks in the skin and give rise to an infection. Boils or cysts could develop if the skin gets irritated. Hidradenitis suppurativa is another condition that may give rise to boils in the armpit region. The development of boils or cysts is often accompanied by other symptoms such as pain, redness, swelling and burning sensation.

Lymphadenitis or inflammation of lymph nodes in the underarm region or an infection in the breast tissuecould also cause armpit pain. Women suffering from breast cancer may also develop a painful lump in the armpit.
