Blocked sweat glands in the armpit, medically known as apocrine or eccrine duct obstruction, can range from a minor nuisance to a painful dermatological condition. The armpit is particularly susceptible due to skin-on-skin friction, moisture, and the presence of hair follicles. Recognizing the symptoms early is key to preventing complications such as infection or inflammation (hidradenitis suppurativa).
