(HealthDay News) -- Blisters occur when the skin is exposed to friction, which results in a tender lump on the skin filled with fluid. They form most often on the hands and feet from new or ill-fitting shoes, or from working with a new tool or instrument.
The best way to prevent blisters is to wear thick socks and comfortable, properly fitting shoes. Give your feet a break by switching shoes frequently and relieving pressure points certain pairs may cause. To protect your hands, it's a good idea to wear gloves when working with tools that could cause blisters.
The Nemours Foundation says blisters will usually heal on their own without treatment. However, you should keep the area clean and dry. Protect the blister with a bandage and by not wearing shoes that will rub or irritate the area.
