Blisters

Blisters are a common occurrence that can typically be treated at home. These fluid-filled lesions can develop for many reasons and can be painful or irritating. The most common reason blisters pop up is wearing new or ill-fitting shoes that rub against your skin. It is also possible for blisters to develop from injuries to the skin such as burns from heat or chemicals, exposure to freezing temperatures, and pinching.

A small, unbroken blister will typically heal on its own. Wear a loose bandage over the area to protect it from irritation.

Blisters that are on the bottom of the foot can be protected from pressure with a circular pad that has a cutout in the middle (the pharmacist at your local drug store can be helpful in finding this). The area over the blister should be left open.

A large, painful blister may have to be drained. It is best not to do this on your own. The broken skin is at a risk for getting infected. Your physician will be able to properly treat the area.

If a blister pops naturally, wash the area with soap and water and apply antibiotic ointment and a fresh bandage. Keep the area dry and clean and let the wound breath at night. Be sure to check the area frequently for any signs of infection.

If any of the following happens, call your physician:

Your blister becomes warm, red, swollen or increasingly painful

You develop a fever or flu like symptoms

Your blister develops pus
