Pustules are red bumps on the skin that are filled with pus. The fluid contains oil that is secreted through the pores of the skin. Pustules usually remain small and red. According to Medline Plus, pustules are commonly associated with acne but may occur as a result of other skin conditions.
Features
Oil-filled red bumps can appear anywhere on the body, according to Medline Plus. The blister-like lesions occur as a result of inflammation caused by infection or irritation. While pustules are most prevalent on the face, back, breastbone and shoulder, they also appear commonly in the groin area and armpits, where you tend to sweat most.
Types
While pustules are most commonly associated with acne, other skin conditions that cause the oil-filled bumps include rosacea, folliculitis, shingles and dermatitis. Smallpox is a deadly disease that has been eradicated worldwide, but relies on vaccinations to maintain its dormancy. Smallpox lesions eventually turn into pustules and are very contagious.
Effects
Most cases of pustules are not serious and respond well to home remedies and time. Serious complications can occur however, making it imperative to see a dermatologist if the bumps do not disappear with about 10 days and cause other symptoms. Vision problems can occur if rosacea bumps enter the eyes for example, according to the American Academy of Dermatology. Pustules formed in response to a viral or bacterial infection can spread to other body parts through the bloodstream.
Side Effects
Many pustules can become itchy and painful. The unsightly bumps can cause self-consciousness and affect your self-esteem if left untreated. Severe allergic reactions that are coupled with difficulty breathing or dizziness may require immediate medical attention. Squeezing the pustules to drain the fluid can lead to infection and scarring.
Treatments
Treatments vary depending on the cause of the pustules. When caused by contact with a substance to which you are allergic, the most effective treatment is to eliminate the substance and avoid further contact according to the American Academy of Dermatology. Doctors often prescribe topical or systemic antibacterial or anti-fungal medications to clear up offending breakouts. Drying agents such as adapalene and tretinoin are prescribed to clear up breakouts due to acne.
