What should you know about random little bumps on skin?

Rough, uniform bumps on the upper arms or thighs can fit Keratosis Pilaris. Tiny pale, firm bumps on the face may be Milia. Bumps after sweating or heat may fit Heat Rash, while red bumps around hairs can suggest Folliculitis. Purple or very itchy bumps deserve a clinician’s review because Lichen Planus is another possibility. A photograph and description of how quickly the bumps appeared can be more useful than guessing from colour alone.

Wash with a mild cleanser, moisturise regularly, and avoid rough scrubs, picking, and tight clothing over the area. Shower after heavy sweating and use clean shaving equipment if bumps cluster where hair is removed. Do not freeze or burn a lesion at home. A dermatologist may recommend a targeted cream, oral antihistamine treatment for itch, or a procedure such as cryotherapy when the diagnosis supports it.

Seek medical advice when bumps are rapidly multiplying, painful, warm, draining, persist despite gentle care, or interfere with sleep. Get urgent help for facial or throat swelling, breathing trouble, widespread blistering, fever with a rapidly changing rash, or severe tenderness. A new bump that bleeds, ulcerates, or does not heal should be assessed rather than repeatedly treated at home.

Ask whether the bumps are follicular, keratin-filled, heat-related, or inflammatory; which ingredients may help; and how long to try the plan. Mention itch, pain, recent heat, shaving, products, medicines, and whether anyone else at home has similar symptoms.
