What should you know about red bumps on my body?

Think about whether the bumps are smooth, rough, scaly, blistered, or filled with fluid. Itching can accompany irritation or an allergic reaction, while warmth, tenderness, swelling, or drainage can point toward infection. Bumps limited to areas exposed to a product, sweat, friction, or sunlight may have a local trigger. Facial flushing with small bumps can occur with rosacea; see the Rosacea page for more context.

A photograph taken in good light and a note of new soaps, medicines, foods, travel, or insect exposure can make a clinical review more useful.

Wash gently with lukewarm water, avoid scrubbing and picking, and use a plain fragrance-free moisturiser if the skin feels dry. Pause newly introduced creams, fragrances, or detergents until the pattern is clearer. Keep the area cool and dry when sweat or rubbing seems to worsen it. Do not apply steroid, antibiotic, or antifungal creams repeatedly without advice, because the wrong product can mask the appearance or irritate skin.

Seek urgent care for trouble breathing, swelling of the lips or tongue, faintness, rapidly spreading redness, severe pain, blistering, or skin that is turning dark. Arrange prompt medical assessment when bumps are hot, increasingly tender, draining pus, accompanied by fever, or appearing in the eyes or mouth. A clinician can examine the distribution and decide whether testing or prescription treatment is needed.

Ask what the pattern most resembles, which products should be stopped, how long to monitor it, and what change would require earlier review. Mention medicines, allergies, recent illness, and whether anyone close to you has a new rash.
