👉 Pustula is a type of skin infection characterized by an inflamed, red, and tender area. It typically appears on the scalp, ears, nose, or on the neck, but it can also spread to other areas due to exposure to the same pathogen. The inflammation is often accompanied by pus, which is a clear fluid that collects in the infected area. Pustula treatment involves applying antibacterial ointments and sometimes using topical antibiotics if necessary.
