Pathophysiology
Miliaria occurs when the sweat gland ducts get plugged due to dead skin cells or bacteria such as Staphylococcus epidermidis, a common bacterium that occurs on the skin which is also associated with acne.
The trapped sweat leads to irritation (prickling), itching and to a rash of very small blisters, usually in a localized area of the skin.
