Pictures of Common Foot Rashes: Causes, Symptoms and Treatment

Common Rashes Affecting Feet

Our feet endure a lot of wear and tear. Constant friction from shoes, moisture from sweat, germs on damp locker room floors - these can lead to a variety of uncomfortable rashes on feet. Identifying exactly what type of rash you have is key to getting the right treatment.

Types of Foot Rashes

Some top rashes known to affect the feet include:

• Athlete's foot
• Dyshidrotic eczema
• Allergic contact dermatitis
• Pityriasis rosea
• Psoriasis

Let’s explore each of these common culprits behind foot rashes, with pictures to help you diagnose your case:

Athlete’s Foot

This fungal foot infection flourishes in damp, closed environments like sweaty shoes and locker rooms. Symptoms include:

• Itchy, burning, or stinging sensations between the toes or bottom of feet
• Red, peeling skin and in severe cases, weeping blisters
• Cracked, white, mushy skin especially between the toes

Dyshidrotic Eczema

This type of eczema causes irritated bumps on the palms of hands and soles of feet. Signs to look for:

• Deep-seated itchy blisters on sides and bottoms of feet
• Blisters enlarge, pop and crust over into calluses
• Peeling skin and cracks between the toes
• Symptoms come and go over time

Allergic Contact Dermatitis

An allergic reaction to chemicals, metals or other footwear materials leads to an itchy rash. Key features:

• Red, wet-looking rash often affecting foot arch and sides
• Burning or stinging discomfort
• Oozing blisters if severe
• Symptoms appear shortly after new exposures

Pityriasis Rosea

A widespread viral rash that can briefly affect feet. Look for:

• Large, pink, oval patches with slightly raised borders
• "Herald patch" - a single spot appearing before more emerge
• Mild itching or burning for a few weeks
• Clears completely in 4 to 12 weeks

Psoriasis

An autoimmune condition where skin cells rapidly build up and shed creates scaly plaques. Feet signs include:

• Red, thickened skin with silvery-white scales
• Itching, stinging, cracking and bleeding
• Painful pitting of nails and nail separation
• Symptoms persist long-term with periodic flares

What Causes These Annoying Foot Rashes?

While the exact cause of each type of foot rash varies, most result from some combination of the following factors:

Fungal Infections

Athlete’s foot is prompted by tinea fungus types that thrive in damp, dark spaces like shoes and lockers. Fungi invade skin cells and multiply, destroying tissues.

Allergic Reactions

Allergic contact dermatitis stems from inflammatory immune reactions to metals like nickel in shoes, rubber chemicals, and topical antifungals. The rash is the body’s attempt to get the irritant away from skin.

Autoimmune Responses

With psoriasis, the immune system falsely attacks healthy skin cells, resulting in a rapid buildup of scales and inflammation. The triggers behind these attacks are still being researched.

Viral Infections

Experts theorize pityriasis rosea originates from viral reactivation within the herpesvirus family. The rash manifests as part of the resulting temporary immune reaction.

Stress and Microtrauma

While the origin is hazy, dyshidrotic eczema seems tied to stress, sweat, and microtears in the skin from friction, allowing irritants entry for an inflammatory response.

Treating Common Foot Rashes

Catching foot rashes promptly is key to relieving symptoms and preventing recurrence. Here is an overview of generalized treatments that may be recommended by your doctor:

Medicated Ointments and Creams

Topical antifungals, steroids, and vitamin D analogues help reduce inflammation and scaling while fighting infections. Examples include miconazole, hydrocortisone, and calcipotriene.

Oral Medications

For moderate to severe rashes, oral steroids, antivirals or antifungals maybe prescribed. Also, targeted medications like biologics can treat underlying autoimmune responses with psoriasis.

Light Therapy

Phototherapy with controlled UV and laser light exposures helps some recurring cases by slowing skin cell turnover and suppressing overactive immunity.

Lifestyle Measures

Preventing irritating friction with well-fitted shoes, socks and inserts allows damaged skin to heal. Gentle scrubbing and moisturizers further aid recovery.

When to See a Doctor

Schedule an urgent podiatry or dermatology appointment if you experience any of the following:

• Foot rash with swelling, oozing fluid or pus
• Red streaks extending from the rash towards the ankle or leg
• Fever over 101°F along with skin redness/pain
• No improvement after 2 weeks of over-the-counter treatments

Skin infections that spread deeper toward tissues and bones can become very serious. Rapid medical care is essential.

Caring for Feet to Prevent Rashes

While some foot rashes haveintrinsic triggers, you can lower risks by implementing good foot hygiene and taking these preventative steps:

Wash and Dry Feet Daily

Use antibacterial soap and water to wash feet daily, carefully drying between the toes. This removes germs, irritants and excess moisture where fungi thrive.

Disinfect Shoes, Socks and Footgear

Use disinfecting sprays and UV lights periodically to kill bacteria and fungi living inside shoes, lace caps and lockers that cause reinfection.

Wear Moisture Wicking Socks

Choose athletic socks which pull sweat from feet and have antimicrobial silver fibers to prevent bacterial and fungal growth.

Rotate Different Pairs of Shoes

Varying shoes gives used pairs more time to fully dry out between wears, deterring fungi.

Apply Foot Powder

Dusting antibacterial foot powder inside socks and shoes helps limit moisture and fights odor and fungi.

Paying close attention to foot hygiene, skin care and protective footwear can make all the difference in blocking annoying rashes!
