Common feet problems

Your feet must last a lifetime. Regular foot care can make sure your feet are up to the task. With proper detection, intervention, and care, most foot and ankle problems can be lessened or prevented.
Experts say some common feet problems may be a symptom of other diseases.

Cold feet

If your toes are always cold, one reason could be poor blood flow, a circulatory problem sometimes linked to smoking, high blood pressure, or heart disease.
The nerve damage of uncontrolled diabetes can also make your feet feel cold. Other possible causes include hypothyroidism and anemia.
A doctor can look for any underlying problems, or let you know that you simply have cold feet.

Foot pain

When feet ache after a long day, you might just blame your shoes. But pain that’s not due to sky-high heels may come from a stress fracture, a small crack in a bone.
One possible cause is exercise that was too intense, particularly high-impact sports like basketball and distance running.
Also, weakened bones due to osteoporosis increase the risk.

Heel pain

The most common cause of heel pain is plantar fasciitis, inflammation where this long ligament attaches to the heel bone. The pain may be sharpest when you first wake up and put pressure on the foot.
Arthritis, excessive exercise, and poorly fitting shoes also can cause heel pain, as can tendonitis.
Less common causes include a bone spur on the bottom of the heel, a bone infection, tumour, or fracture.

Dragging your feet

Sometimes the first sign of a problem is a change in the way you walk – a wider gait or slight foot dragging. The cause may be the slow loss of normal sensation in your feet, brought on by peripheral nerve damage.
About 30 per cent of these cases are linked to diabetes.
Nerve damage also can be due to infection, vitamin deficiency, and alcoholism. In many cases, no one knows what caused the nerve damage.
Other possible causes for foot dragging include problems with the brain, spinal cord, or muscles.

Clubbed toes

In clubbing, the shape of the toes (and often the fingers) changes. The nails are more rounded on top and curve downward.
Lung disease is the most common underlying cause, but it also can be caused by heart disease, liver and digestive disorders, or certain infections.
Sometimes, clubbing runs in families without any underlying disease.

Swollen feet

This is usually a temporary nuisance caused by standing too long or a long flight, especially in a pregnant woman.
In contrast, feet that stay swollen can be a sign of a serious medical condition. The cause may be poor circulation, a problem with the lymphatic system, or a blood clot.
A kidney disorder or underactive thyroid can also cause swelling.
If you have persistent swelling of your feet, see a physician.

Burning feet

A burning sensation in the feet is common among diabetics with peripheral nerve damage.
It can also be caused by a vitamin B deficiency, athlete’s foot, chronic kidney disease, poor circulation in the legs and feet, or hypothyroidism.

Sores that don’t heal

Foot sores that will not heal are a major warning sign for diabetes. Diabetes can impair sensation in the feet, circulation, and normal wound healing, so even a blister can become a troublesome wound.
Those sores also are prone to infection. Diabetics should wash and dry their feet and check them for any wounds every day. Slow-healing of sores also can be caused by poor circulation from conditions such as peripheral artery disease.

Itchy feet

Itchy, scaly skin may be athlete’s foot, a common fungal infection.
A reaction to chemicals or skin care products, called contact dermatitis, can cause itching, too, along with redness and dry patches.
If the skin on itchy feet is thick and pimple-like, it may be psoriasis, an over-reaction of the immune system.
Medicated creams can relieve the symptoms.

Claw toe

This foot deformity can be caused by shoes that are tight and pinch your toes or by a disease that damages nerves, such as diabetes, alcoholism, or other neurological disorder.
Your toes will be bent upward as they extend from the ball of the foot, then downward from the middle joint, resembling a claw.
They may respond to stretching and exercises of the toes or you may need special shoes or even surgery.

Foot spasms

A sudden, sharp pain in the foot is the hallmark of a muscle spasm or cramp, which can last many minutes. Overwork and muscle fatigue are common causes.
Other causes include poor circulation, dehydration, or imbalances in potassium, magnesium, calcium, or vitamin D levels in the body. The changing hormone levels of pregnancy or thyroid disorders may play a role.
If spasms are frequent or severe, see a doctor. Strengthening exercises can help with muscle fatigue.

Yellow toenails

Your toenails tell a lot about your overall health. A fungal infection often causes thickened yellow toenails.
Thick, yellow nails also can be a sign of an underlying disease, including lymphedema (swelling related to the lymphatic system), lung problems, psoriasis, or rheumatoid arthritis.

White nails

Injury to the nail or illness anywhere in the body can cause white areas in the nails.
If part or all of a nail separates from the nail bed, it can appear white, and may be due to an injury, nail infection, or psoriasis.
If the nail is intact and most of it is white, it can sometimes be a sign of a more serious condition, including liver disease, congestive heart failure, or kidney disease.
