The appearance of painful lumps which are usually referred to as boils or lumps can be irritating especially when they occur on the armpit. Armpit lump can appear due to bacterial growth or growth in the lymph nodes. Lymph nodes are basically small glands that are present throughout the body and are responsible for maintaining the body’s balance. Apart from lymph nodes, an infection and cyst growth can also cause lumps.

Armpits are sensitive areas on the body. Excessive sweating in this area makes it vulnerable and exposes it to bacteria and other germs. Painful lumps usually appear when sweat and germs get trapped in the hair follicle. The odds of this happening multiple when the armpits are not washed regularly. This is the reason that hygiene plays a great part in your health.

  1.    Hidradenitis suppurativa

  1.    Allergic reactions

Sometimes the appearance of lumps is a sign of a reaction to either a vaccination shot or any other medicine. These lumps occur as the inflammation caused in the lymph nodes swell. Usually, this condition is not much troublesome. However, if the lumps stay for a relatively long time or become extremely painful then contact your doctor as soon as possible.

Such boils usually appear after an injury or any accident that may hurt the skin or they may appear after a surgery. These are usually skin colored and appear in small sizes. You can consult your doctor but they may vanish themselves.
