What should you know about folliculitis on arms treatment?

Folliculitis is inflammation around a hair follicle. On the arms, it may look like scattered red bumps, pus-filled spots, soreness, or itch. Shaving, friction from clothing or equipment, sweating, and blocked follicles can contribute. Bacterial folliculitis is one possibility, but not every bump is an infection. A clinician can examine the pattern and decide whether this is [Folliculitis](/conditions/folliculitis/) or another cause of [Skin Bumps](/symptoms/skin-bumps/).

Wash gently, pat dry, and avoid scrubbing or picking. Pause shaving or waxing over the affected skin until it settles, and reduce rubbing from tight sleeves or sports gear. Change out of sweaty clothing and use a clean towel. If a clinician finds a bacterial infection, they may recommend [Topical Antibiotic Therapy](/treatments/medical-dermatology/topical-antibiotic-therapy/) or, when appropriate, oral [Antibiotics For Skin Infection](/treatments/medical-dermatology/antibiotic-therapy-for-skin-infection/). Do not use leftover antibiotics or share someone else’s medicine.

Arrange an assessment if bumps keep returning, spread, become painful, drain, or do not improve with gentle care. Seek prompt help when redness expands quickly, the skin becomes hot and swollen, or you feel feverish or unwell. Recurrent bumps may need a closer look for ingrown hairs, irritation, or another skin condition.

Could shaving, friction, or a product be triggering these arm bumps? Do they look infected or more like irritation? Which treatment is suitable for my skin, and how should I prevent the problem from returning?
