What Causes Painful Blisters Between the Toes and How to Treat Them

What Causes Blisters Between the Toes?

Blisters between the toes are a common foot problem that can cause pain and discomfort. They form when there is repeated rubbing or friction between toes, often caused by ill-fitting shoes or socks. The constant irritation leads to a buildup of fluid under the top layer of skin, creating a blister.

There are several potential causes of blisters between the toes:

Wearing High Heels or Narrow Shoes

Shoes that are too tight or have a very narrow toe box put pressure on toes and dont allow them enough room. This can force toes to press together and rub against each other with every step, resulting in blisters.

Excessive Sweating

Sweaty feet lead to moisture buildup between toes that causes skin maceration, making it more vulnerable to friction blisters. The moist environment is also ideal for bacterial overgrowth.

Socks That Are Too Tight

Socks that constrict toes and dont allow proper air circulation cause irritation. The fabric bunches up between toes and creates friction.

Intense Physical Activity

Runners and athletes who engage in frequent high-impact activities that involve a lot of foot motion may develop blisters more readily. The intensity of activity leads to excess friction.

Walking Barefoot

Going barefoot, especially for long periods of time or over rough terrain, can lead to blisters between toes. Without the protection of shoes and socks, toes are directly exposed to friction and pressure.

Toenail Infections

Infections like toenail fungus cause thickening and distortion of toenails. This leads to pressure between the toes, increasing friction.

Bunions

Bunions alter the alignment of the big toe, forcing it inward toward other toes. This change in positioning rubs the big toe against the second toe, resulting in blisters.

Hammertoes

Hammertoes cause toes to bend unnaturally, forcing them to press against each other and creating prime conditions for blister formation.

Rheumatoid Arthritis

Joint inflammation from autoimmune conditions like rheumatoid arthritis can cause deformity and displacement of toes. This leads to abnormal rubbing and friction between toes.

Signs and Symptoms of Blisters Between Toes

The most common signs and symptoms of blisters between the toes include:

Visible Blister

A noticeable, fluid-filled blister is present between two toes. The size can range from very small to large.

Redness and Swelling

The skin between affected toes appears irritated, red and swollen from continuous rubbing.

Tenderness

There is pain and tenderness when the blistered area between toes is touched.

Throbbing or Burning Pain

The friction blister causes a painful throbbing or burning sensation between the toes.

Itching

The blistered skin itches from irritation caused by movement and contact between toes.

Difficulty Wearing Shoes

Any pressure on the blister from wearing shoes is extremely uncomfortable.

Drainage or Bleeding

If the blister pops, there may be oozing of clear fluid or bleeding.

Walking Difficulty

Discomfort from the blister makes walking painful and challenging.

Risk Factors for Developing Blisters Between Toes

Certain individuals have a greater risk of developing troublesome blisters between the toes:

Athletes

Runners, hikers, swimmers, and sports players who engage in frequent intensive activity involving the feet.

Military Service Members

Combat boots and tactical footwear can cause blisters.

Children

Their feet sweat more and they are prone to outgrowing shoes quickly, wearing ill-fitting pairs.

People with Diabetes

Neuropathy causes reduced sensation and they may not notice blisters forming.

Older Adults

Declining circulation results in drier feet more prone to blistering.

People with Obesity

Excess weight places greater pressure on feet and causes more friction.

Individuals with Foot Deformities

Bunions, hammertoes, flat feet increase abnormal pressure points and friction.

People with Rheumatoid Arthritis

Joint inflammation leads to toe deformities and displacement.

Pregnancy

Hormonal changes and extra weight can cause foot swelling and irritation.

Complications Associated with Blisters Between Toes

Ignoring or failing to properly treat blisters between the toes can lead to potentially serious complications:

Cellulitis

This bacterial skin infection causes spreading redness, swelling and tenderness in the foot.

Toe Paronychia

An infection of the skin around the toenails and cuticles of the affected toes can occur.

Abscesses

Pus-filled pockets of infection under the skin develop from worsening blister infections.

Chronic Pain

Repeated blistering between toes causes nerve damage and leads to debilitating chronic neuropathic pain.

Gangrene

A severe loss of blood flow from infection can lead to decay and death of toe tissues.

Amputations

In the worst cases, untreatable gangrene requires full or partial amputation of diseased toes.

Permanent Nail Loss

A severe infection from a toe blister can destroy the nail matrix and prevent nail regrowth.

Bone Infection (Osteomyelitis)

Bacteria from infected blisters spreads into toe bones, damaging them.

Blood Poisoning (Sepsis)

Rampant foot infection enters the bloodstream and becomes life-threatening.

When to See a Doctor for Blisters Between Toes

You should make an appointment with your doctor if:

• Blisters keep recurring between the toes
• Blisters are very painful or limit your ability to walk
• Signs of infection develop, like pus, foul odor, fever or red streaks
• Diabetics get a blister on their foot
• The blister does not begin to heal within a few days
• A blister pops and does not drain properly

Seeking prompt medical treatment is crucial to prevent complications. Infections can rapidly spread from blisters between the toes.

Home Treatment and Prevention of Blisters Between Toes

You can treat blisters between the toes at home and take steps to prevent them from developing:

Rest and Elevate Feet

Stay off your feet and keep them raised above heart level to minimize swelling and discomfort.

Apply Ice Packs

Icing the affected area reduces inflammation and pain symptoms.

Use Antibiotic Ointment

Apply antibiotic creams or petroleum jelly to prevent infection and speed healing.

Cover with Padding

Protect blisters between toes with foam, gel pads, or moleskin to prevent friction.

Wear Clean Socks and Breathable Shoes

Allow feet to stay cool and dry to avoid conditions that lead to blisters.

Soak Feet in Salt Water

Salty water draws out fluid from blisters to help them drain and aids healing.

Try Over-the-Counter Medications

Anti-inflammatories like ibuprofen can ease pain. Topical hydrocortisone cream reduces itching.

Keep Feet Clean and Dry

Practice good foot hygiene to prevent infections from developing.

Wear Properly Fitting Footwear

Shoes that are well-fitted to your feet and socks that arent too tight reduce friction between the toes.

Moisturize Regularly

Apply foot creams and moisturizers to keep your feet soft and smooth.

Change into Clean Socks Frequently

Sweaty, damp socks that foster bacterial overgrowth make blisters more likely.

Medical Treatments for Stubborn or Infected Blisters Between Toes

See a podiatrist for treatment if home care does not resolve blisters between the toes. Medical options may include:

Oral Antibiotics

Antibiotics kill off bacterial infections stemming from popped or damaged blisters.

Prescription Ointments

Topical antibiotic, antifungal, or steroid creams and gels treat infections and inflammation.

Draining and Debriding

The blister is safely drained of fluid and damaged tissue is removed.

Toenail Removal

Infected toenails causing blisters may need to be fully or partially removed.

Padding and Taping

Cushioning and adhesive tape protects blisters and prevents irritation from shoe friction.

Custom Orthotics

Shoe inserts properly redistribute weight and reduce pressure points on the feet.

Toe Spacers

Devices placed between toes realign their positioning and minimize rubbing.

Bunion and Hammertoe Surgery

Corrective surgery fixes alignment and prevents deformity-related blistering.

Footwear Modifications

Well-fitted, breathable shoes with ample toe room may be recommended.

Preventing Blister Formation Between Toes

Making some adjustments to foot care and shoe choices can help prevent those painful blisters from developing between your toes:

Wear Moisture Wicking Socks

These socks keep feet drier and reduce friction.

Apply Powders and Lubricants

These products decrease moisture and rubbing between your toes.

Wear Double Layer Socks

The extra inner sock acts as a liner and reduces skin irritation.

Break in New Shoes Gradually

Slowly introducing new shoes gives your feet time to adapt to them.

Shop for Shoes Later in the Day

Feet tend to swell during the day, so buy shoes that fit well at that time.

Select Shoes with a Wide Toe Box

Footwear designed with a roomy toe area prevents crowding and rubbing.

Choose Flexible, Breathable Materials

Leather, mesh and knit shoes allow needed air circulation.

Replace Footwear Regularly

Old, worn shoes lack support and cushioning to protect from blisters.

When to See a Podiatrist for Blisters Between the Toes

Consult a foot doctor if you experience:

• Frequent recurrences of painful blisters between the toes
• Infected blisters with pus, redness, swelling, fever
• Diabetic foot blisters, which can be dangerous
• Discomfort that interferes with walking or athletic activity
• Blisters related to bunions, hammertoes or deformed feet
• Slow healing blisters lasting over one week
• Blisters that do not respond to home treatment

A podiatrist can provide treatment to heal blisters as well as address any underlying foot conditions contributing to repeated blistering between the toes.
