Common Foot Problems

Bunions

If you have a bunion, you know it can be a painful enlargement at the joint of the big toe. The skin over the joint becomes swollen and is often quite tender. Bunions can be inherited as a family trait, can develop with no recognizable cause or can be caused by shoes that fit poorly.

A bunion is an enlargement at the joint of the big toe.

An important part of treatment is wearing shoes that conform to the shape of the foot and do not cause pressure areas. This often alleviates the pain. In severe cases, bunions can be disabling. Several types of surgery are available that may relieve pain and improve the appearance of the foot. Surgery is usually done to relieve pain and is not meant for cosmetic purposes.

Heel Pain

Circled area is a common site of heel pain.

Heel pain is extremely common. It often begins without injury and is felt under the heel, usually while standing or walking. It is usually worst when arising out of bed.

Inflammation of the connective tissue on the sole of the foot (plantar fascia) where it attaches to the heel bone is the most common cause of pain. It is often associated with a bony protrusion (heel spur) seen on X-ray studies.

Most cases will improve spontaneously. Heel and stretching, medication to reduce swelling of the soft tissues in your foot and shoe inserts are quite helpful. If pain continues, steroid injections or walking casts are used. Only in the most troubling and prolonged cases is surgery recommended.

Morton’s Neuroma

Morton’s neuroma is caused by a nerve being pinched. This pinching usually results in pain between the third and fourth toes. Tight shoes can squeeze foot bones together. The nerve responds by forming a neuroma, a build up of extra tissue in the nerve. The neuroma results in pain, that may radiate into the toes.

Treatment usually involves wearing wider shoes and taking oral medications to decrease the swelling around the nerve. A pad on the sole of the foot to spread the bones is often helpful. Your doctor may also inject cortisone around the nerve. If your difficulty continues, surgery to remove the neuroma may be suggested.

Corns and Calluses

Corns and calluses are caused by pressure on the skin.

Corns and calluses are caused by pressure on the skin of your foot. They may occur when bones of the foot press against the shoe or when two foot bones press together.

Common sites for corns and calluses are on the big toe and the fifth toe. Calluses underneath the ends of the foot bones (metatarsals) are common. Soft corns can occur between the toes.

Treatment involves relieving the pressure on the skin, usually by modifying the shoe. Pads to relieve the bony pressure are helpful, but they must be positioned carefully. On occasion, surgery is necessary to remove a bony prominence that causes the corn or callus.

Hammertoes

Tight shoes make hammertoes painful.

Hammertoes are one of several types of toe deformities. Hammertoes have a permanent sideways bend in your middle toe joint. The resulting deformity can be aggravated by tight shoes and usually results in pain over the prominent bony areas on the top of the toe and at the end of the toe. A hard corn may develop over this prominence.

Treatment usually involves a shoe to better accommodate your deformed toe. Shoe inserts or pads also may help. If, after trying these treatments, you are still having marked difficulty, surgical treatment to straighten the toe or remove the prominent area of bone may be necessary.

Plantar Warts

Plantar warts can be treated.

Plantar warts occur on the sole of the foot and look like calluses. They result from an infection by a specific virus. They are like warts elsewhere, but they grow inward. The wart cannot grow outward because of weight placed on it when you stand. You may experience severe pain when walking, and can have just one or many plantar warts. Plantar warts are extremely difficult to treat, but success has been achieved with repeated applications of salicylic acid (available over the counter) to soften the overlying callus and expose the virus. Other treatments include injection of the warts with medication, freezing the warts with liquid nitrogen and, very rarely, surgery.
