Skin blisters and bumps

Skin blisters and bumps are common skin symptoms that can appear as reddish, clear or fluid-filled small raised spots on the skin. They often occur on the hands, arms, face or legs, and there may be several different underlying causes. In Finland, common triggers include heat rash (especially in infants, but sometimes also in adults due to sweating and occlusive clothing), allergic reactions, insect bites, and phytophotodermatitis caused by the combined effect of sunlight and plants. In phytophotodermatitis, red streaks or blisters may appear on the skin, especially in areas that have first been exposed to chemicals from plants and then to sunlight.

Most often, skin blisters and bumps are harmless and heal on their own. However, they can sometimes be a sign of inflammation, an allergic reaction or another condition that needs treatment. If the blisters spread quickly, are painful, become inflamed, are associated with general symptoms such as fever, or do not heal on their own, it is advisable to seek an assessment by a healthcare professional. This helps ensure proper treatment and rule out possible more serious causes.
