(HealthDay News) -- Blisters -- bumps on the skin that contain fluid -- can be caused by injury, infections or allergic reactions.
Treatment for blisters varies, depending on the cause. But here are some general guidelines for blister first-aid, courtesy of the Loyola University Health System.
Wash the area with soap and water. Applying a cold compress or ice pack may help reduce discomfort and swelling. Remember to keep the blister area clean and dry. Don't puncture or burst the blister. If it does burst, apply a bandage or dressing to keep it clean.
Watch the blister for signs of infection. Symptoms may include swelling, redness, pus formation, drainage, increased warmth, or pain. If you detect any signs of infection, call your doctor as soon as possible. You may require antibiotics.
