Most blisters on the feet are caused by friction and do not require medical attention. New skin will form underneath the affected area and the fluid built up in the blister is simply absorbed back into the tissue.
Do not puncture a blister unless it is large, painful or likely to be further irritated. If you have to pop a blister, use a sterilized needle. Wash the area thoroughly, then make a small hole and gently squeeze out the clear fluid. Apply a dab of antibiotic ointment and keep covered with a sterile dressing to help protect against infection. Do not remove the skin over a broken blister. The new skin underneath needs this protective cover.
If the fluid is white or cloudy, the blister is infected and needs medical attention.
You can prevent blisters by breaking in new shoes gradually, and putting petroleum jelly or an adhesive bandage such as moleskin on areas that take the rub-before the blister happens. Be sure to wash and dry your feet daily to prevent bacterial infections.
