Foot Ulcers vs. Foot Blisters

Foot ulcers can easily be mistaken for blisters. Here are a few differences to help you figure out what you have.

Foot Blisters

• A blister is a pocket of fluid beneath the skin.
• A small, unbroken blister will likely heal on its own.
• The area can pop on its own. If it does, keep it clean and dry.
• If the area is warm, red, swollen, and/or painful, it is time to see a doctor.
• The most common cause of blisters is wearing shoes that don’t fit properly.

Foot Ulcers

• A foot ulcer is an open wound.
• Most commonly found on the ball of the foot, bottom of the big toe, or side of the foot.
• If you are diabetic, you are at an increased risk for foot ulcers.
• Foot Ulcers require medical attention. They can lead to serious infections if not treated properly.
• It may take months for ulcers to heal.

If the area is not healing on its own, or you think it may be an ulcer, make an appointment with your doctor. He will help to get the area healed properly.
