Plucking may be a quick and easy way to remove unwanted body hair, but it isn't always the safest or most effective. And plucking underarm hair is no exception. Plucking underarm hair can be painful, time-consuming, and if done incorrectly, can cause irritation, ingrown hairs, or scarring.

Lymph nodes are part of the body's immune system, acting as filters that remove potentially harmful substances from the body. Swollen lymph nodes in the armpit can be a sign of infection or injury. In particular, swollen lymph nodes after plucking armpit hair is a risk factor for local infection. One should not dismiss and overlook other causes of swollen lymph nodes.
