A foot infection occurs when bacteria or fungi enter the skin through a cut, blister, or open wound and begin to spread. Some infections, like athlete’s foot and toenail fungus, are common and manageable, while others, such as cellulitis and infected ulcers, can have serious consequences for your overall health. At Performance Foot & Ankle, our podiatrists in Thousand Oaks, CA provide prompt, expert treatment to stop infections before they become something worse.

Understanding Foot Ulcers

Foot ulcers are open sores or red craters that develop on the surface of the skin, usually on the bottom or sides of the foot. Most people notice an ulcer early because it is painful and makes walking difficult. However, patients with diabetes and peripheral neuropathy may not feel sensations in their feet, making it possible to develop an ulcer without realizing it.

Ulcers must be treated quickly because they greatly increase the risk of infection. Check the bottoms and sides of your feet regularly for red sores surrounded by dry, cracked, or calloused skin, especially if you have diabetes or circulation problems. Learn more about our diabetic foot care services.

Common Causes of Foot Infections

  • Injuries, cuts, and puncture wounds
  • Untreated blisters
  • Diabetes and poor circulation
  • Ingrown toenails and fungal nail infections
  • Athlete’s foot and cracked skin
  • Pressure from ill-fitting shoes or corns and calluses

Signs and Symptoms of a Foot Infection

If you have injured your foot, watch the wound carefully as it heals. Signs that an infection may be forming include:

  • Redness or changes in skin color around the wound
  • Skin that is warm to the touch
  • Swelling and increasing pain
  • Unusual odor from the wound
  • Pus or other drainage
  • Toenail discoloration
  • Fever or chills

An infected wound requires professional medical care. Schedule an appointment right away if you notice any of these symptoms.

How We Treat Foot Infections and Ulcers

Treatment depends on the type of infection and how far it has progressed. Your podiatrist may use:

  • Debridement – Removal of dead tissue and callused skin around an ulcer to promote healing
  • Antibiotics or antifungals – Oral or topical medications to eliminate infection
  • Wound dressings – Advanced bandages and wound care products to protect the area
  • Offloading – Protective footwear, boots, or custom orthotics to relieve pressure
  • Imaging – In-office x-rays and ultrasound to check for deep infection or foreign bodies
  • Surgery – In some cases, surgical treatment may be required to remove infected tissue

For patients with nonhealing diabetic ulcers, our practice is also enrolling participants in a diabetic foot wound clinical trial.

Frequently Asked Questions About Foot Infections and Ulcers

How do I know if my foot wound is infected?

Signs of infection include redness, warmth, swelling, increasing pain, pus or drainage, an unusual odor, and fever. If you notice any of these symptoms, contact a podiatrist promptly.

Why are foot ulcers dangerous for people with diabetes?

Diabetes can reduce circulation and sensation in the feet, so ulcers may go unnoticed and heal slowly. This increases the risk of serious infections that can spread to the bone.

What is debridement?

Debridement is the removal of dead tissue and callused skin from around an ulcer. It helps the wound heal faster and reduces the risk of infection.

How long does it take a foot ulcer to heal?

Healing time depends on the size and depth of the ulcer, your circulation, and how well pressure is kept off the area. Many ulcers heal within several weeks with proper care, while others take longer.

Can I treat a foot infection at home?

Minor issues like athlete’s foot may respond to over-the-counter treatments, but infected wounds, ulcers, and spreading redness should always be evaluated by a podiatrist.

How can I prevent foot ulcers?

Inspect your feet daily, keep them clean and moisturized, wear well-fitting shoes, never walk barefoot, manage your blood sugar, and schedule regular podiatry exams if you have diabetes.

When is a foot infection an emergency?

Seek immediate care if you have rapidly spreading redness, fever, chills, severe pain, or a wound with black or dead-looking tissue, especially if you have diabetes.
