Swollen upper lip with tiny bumps

The location and sensation provide useful clues. Itchy bumps after a new product or food can fit irritation or allergy. Tender red bumps may follow friction, shaving, or a blocked follicle. Clusters of fluid-filled blisters suggest a different problem from firm, skin-coloured spots. Bumps inside the lip are assessed differently from bumps on the skin. A photograph taken before the appearance changes can help a clinician compare the pattern.

Pause new cosmetics, lip balms, whitening products, and fragranced toothpaste. Wash the surrounding skin gently, keep your hands away, and use a cool compress if the area feels swollen. Do not pop the bumps or scrub the lip, because this can worsen inflammation and introduce bacteria. Avoid sharing lip products. If swelling began after a medicine, food, injection, or dental treatment, record the timing and contact a clinician before repeating the exposure. Treatment depends on whether the cause is allergic, inflammatory, or infectious.

Get emergency help for swelling of the tongue or throat, wheezing, trouble breathing or swallowing, voice change, widespread hives, or faintness. Seek prompt review when bumps are rapidly spreading, intensely painful, associated with fever or pus, or not settling after the suspected irritant is removed. Recurrent swelling should be assessed even if each episode improves, because identifying the trigger can guide prevention.

Are the bumps on the skin or inside the lip? Could a product, food, medicine, shaving habit, or dental treatment explain them? Should I use an antihistamine or another treatment? What should I do if the swelling returns?
