Bacterial folliculitis on the legs: causes and care

The rash may consist of scattered or clustered bumps, each surrounding a leg hair. Some spots itch or feel tender, and a small amount of pus or crust can appear. Shaving, waxing and epilation can leave microscopic irritation around follicles; tight exercise wear, boots, sweat and repeated rubbing can add further damage. An ingrown hair can create a similar bump and may become inflamed without a bacterial infection. Widespread rough plugs without tenderness may reflect another follicular condition rather than bacterial disease.

Temporarily stop hair removal and choose loose, breathable clothing. Gently wash after sweating, dry the skin without rubbing, and launder clothing that contacts draining spots. Keep razors personal, clean reusable devices as directed, and discard a blade that has passed over infected skin. A clean warm compress may soothe a small tender area. Avoid squeezing lesions or digging out hairs. Persistent or extensive inflammation may require clinician-prescribed topical or oral medicine after the cause and depth are assessed.

Seek timely assessment if lesions recur after hair removal, cover a growing area, become deep or painful, drain repeatedly, or do not improve with basic care. Urgent evaluation is appropriate for fever, rapidly spreading warmth or redness, red streaking up the leg, pronounced swelling, severe pain, or difficulty bearing weight. A person with reduced circulation, reduced sensation, diabetes or weakened immunity should arrange early review of an inflamed leg lesion.

Mention how you remove leg hair, when the outbreak began, whether it follows exercise or tight clothing, and whether anyone sharing a household has similar lesions. Ask if a swab, drainage or prescription treatment is appropriate, and request a safer hair-removal plan for use after healing.
