can be a positive thing because it allows for non-invasive self-care before inflammation or infection develops.

The armpit is home to two main types of sweat glands: eccrine and apocrine. Eccrine glands are found all over the body and produce a watery, odorless sweat to regulate temperature. Apocrine glands are concentrated in areas with hair follicles, like the armpits and groin. These glands produce a thicker fluid that, when mixed with skin bacteria, creates body odor. A "blocked sweat gland" usually involves these follicles or the ducts leading from them. Common Causes of Blockages Several factors can lead to a lump or bump in the armpit:

This indicates the body’s ability to clear the blockage without medical intervention, unlike deeper or recurrent lesions that may scar or form tunnels (sinus tracts).
