A blister is a small pocket of fluid that forms on an area of the body. These bubbles can vary in size and can occur for different reasons. You may develop one after a skin burn, infection with fungus or bacteria, an insect bite, or trauma. Depending on its location, a blister can interfere with normal, everyday tasks. For example, if you have a blister on your feet, you may have difficulty walking, exercising, or standing for long periods of time.
