Who hasn’t had a blister at some point in their life? If you’ve got a blister on your foot, you’ll know it pretty quickly. However, knowing what to do with that painful, fluid-filled bump is another story. Dr. Kenneth R. Wilhelm, the board-certified podiatrist at Clifton Foot & Ankle Center, is here to help you make sense of the assorted advice you may have heard about caring for a blister.
Why do blisters form?
Skin is sensitive. Repeated friction, rubbing, or excess pressure on sensitive skin can cause blisters on your feet. For example, if you go on a hike wearing shoes that are too small, the pressure on your heel can cause a blister. Similarly, your feet can slide around in shoes that are too big. The repetitive rubbing of the toe against the toe box can aggravate the skin into a blister.
Leave ‘em alone
Dr. Wilhelm recommends that you don’t pop a blister. As annoying as it may be, the bubble is there to protect the damaged skin beneath it. Popping a blister will open the skin up to infection. The best way to treat a blister is to leave it alone. It may help to cover it loosely with a bandage. If a blister pops on its own, wash it gently with soap and water. Leave the skin flap in place, coat the area with antibacterial ointment, and cover it with a clean bandage.
When to see the doctor
Be wary of blisters on your feet that aren’t caused by obvious friction from shoes. They can be a sign of the viral infection HFM (hand, foot, and mouth disease) or a systemic disease such as eczema, shingles, or chicken pox. If you notice blisters on your feet that seem to have popped up out of nowhere, accompanied by pain, a fever or a feeling of malaise, consult your doctor.
