Other Foot Rash Causes

There are a number of other possible causes of rashes on feet, but theytend to be less common or affect more of the body, rather than beingconfined to the foot or lower legs.

1. Psoriasis

Psoriasis is a chronic skin disease causing red, scaly, itchy patches. Skin rashes from psoriasis are caused by rapid overproduction of skin cells due to a problem with the immune system. Psoriasis skin lesions range from small, localised patches to major eruptions affecting the whole body.

Skin rashes from psoriasis tends to occur on the soles of the feet. It affects 2-4% of the population. Symptoms usually go through recurrent cycles of flaring up for a few weeks or months then settling down.

2. Scabies

Scabies is a contagious skin condition caused by a parasite burrowing under the skin. Scabies affects 1.5% of the population and causes intense itching which is worse at night.

Superficial burrows from the mite are visible through the skin, with the foot rash appearing in lines accompanied by small, red spots commonly in the webs of fingers and toes.

3. Insect Bite

A bite to the foot or ankle can produce a skin rash. It tends to be asmall, localised spot or group of spots which are itchy and the foot rash settles within a few days.

What Are Itchy Feet

Feet are exposed to many potential irritants like allergens, bugs, and fungus that can cause itchiness. Your feet also spend long hours in the potentially moist, hot environment of your shoes and socks, which can be a breeding ground for bacteria and fungi.

The most common causes of itchy feet are contact dermatitis, fungal infections like athletes foot, or bug bites from scabies, mosquitos, or bed bugs. These conditions may also cause a rash, blisters, or scaly skin.

In some cases, conditions such as diabetes and kidney or liver disease can cause Inflammation or affect the nerves, making your feet feel itchy.

Many causes of itchy feet can be treated with topical or oral anti-itch or antifungal medications, or topical steroids.

Pro Tip

A common misconception is that itchy feet are always caused by a foot fungus. Many times I see patients who come in for foot fungus, but when I look at the feet it’s eczema, dermatitis, or psoriasis. It may even be an internal cause of itching like liver or kidney diseases. Dr. Lauren Levy

The Circulation Responds To Temperature

Although the exact cause of chilblains remains unknown, it is thought to be associated with the bodys reaction to cold weather. The bodys circulatory system comprises arteries, veins and capillaries that carry blood to every cell. The circulatory system is sensitive to temperature.In hot conditions, the body expands blood vessels close to the skin so that excess heat can be lost to the air, thereby cooling the body. In cold weather, these blood vessels constrict to conserve body heat. This constriction can starve extremities, such as the toes, of blood and warmth, if your peripheral circulation is sluggish.

  • pain at the point of impact that may last for a few hours
  • a crooked or abnormal appearance to the toe

Skin Infection Of The Foot

An infection of the skin of the foot is almost always either fungal or bacterial. A fungal infection of the foot is called tinea pedis, or athlete’s foot. It is caused by different types of dermatophyte fungus and is commonly found in damp places such as showers or locker room floors. A bacterial infection anywhere on the skin is called cellulitis if it extends under the skin. It can develop after a break in the skin allows bacteria to enter and begin growing. These bacteria are most often either Streptococcus or Staphylococcus, which are found throughout the environment.

Most susceptible are diabetic patients, since high blood sugar interferes with healing and wounds can easily become chronic and/or deeply infected. Diagnosis is made through physical examination by a medical provider.

Treatment for either a fungal or bacterial infection involves keeping the skin dry and clean at all times. A fungal infection is treated with topical and/or oral antifungal medications, while a bacterial infection will be treated with topical and/or antibiotic medications.

Rarity: Uncommon

Top Symptoms: fever, foot pain, foot redness, warm red foot swelling, swollen ankle

Symptoms that always occur with skin infection of the foot: foot redness, foot pain, area of skin redness

If you have itchy skin, here are some things that may help:

  • Try not to scratch the area. The more you scratch, the more the skin will itch.
  • Keep your nails short to prevent breaking the skin if you do scratch.
  • A cool bath or shower may help provide short-term relief, but excessive showering or bathing may make it worse.
  • After a bath or shower gently pat yourself dry with a clean towel. Do not rub or use the towel to scratch yourself.
  • Do not use any soaps, shower gels or foam bath products as they can dry the skin and make the itching worse. Use a soap-free wash.
  • Use moisturiser all over the skin at least 2 times a day, and more often if the skin feels dry. You can buy cooling moisturisers that contain menthol to soothe the itch.
  • Try to wear loose cotton clothing which can help prevent you overheating and making the itch worse. Avoid fabrics which irritate your skin like wool or scratchy fabrics.
  • Reducing stress and considering meditation, yoga, hypnosis or exercise can be helpful.

Your pharmacist may be able to recommend some products which can help with itchy skin.
