The initial trigger is often allergic dermatitis, which can stem from environmental allergens like pollen and dust mites, or from food sensitivities. The damaged skin becomes infected, and the infection creates more itch and pain, prompting even more scratching.
The constant moisture and trauma break the skin barrier, creating the perfect environment for bacteria and yeast that normally live on the surface to overgrow and cause infection.
