Anatomy of the foot:
The foot is one of the most complex parts of the
body, consisting of 28 bones connected by numerous joints, muscles,
tendons, and ligaments. The foot is susceptible to many stresses. Foot
pain and problems can cause pain, inflammation, or injury, resulting in
limited movement and mobility.
What are the different types of foot problems?
Foot pain is often caused by improper foot
function. Improperly fitted shoes can worsen and, in some cases, cause
foot problems. Shoes that fit properly and give good arch support can
prevent irritation to the foot joints and skin. There are many types of
foot problems that affect the heels, toes, nerves, tendons, ligaments,
and joints of the foot.
The symptoms of foot problems may resemble other medical conditions and problems. Always consult your physician for a diagnosis.
What are heel spurs?
A heel spur is a bone growth on the heel bone. It
is usually located on the underside of the heel bone where it attaches
to the plantar fascia, a long band of connective tissue running from the
heel to the ball of the foot. This connective tissue holds the arch
together and acts as a shock absorber during activity. If the plantar
fascia is over-stretched from running, wearing poor-fitting shoes, or
being overweight, pain can result from the stress and inflammation of
the tissue pulling on the bone. Over time, the body builds extra bone in
response to this stress resulting in heel spurs. Treatment options may
include:
- rest
- cold packs
- anti-inflammatory medication such as ibuprofen
- proper stretching prior to activity
- proper footwear or shoe inserts
- corticosteroid injections
- surgery (for more severe, prolonged conditions)
What is a corn?
Corns are yellowish, callus growths that develop on
top of the toes. Corns develop because of abuse or stress. Often, a
corn develops where a toe rubs against a shoe or another toe. Corns can
cause extreme discomfort and pain. Treatment may include:
- trimming the corn by shaving the layers of dead skin
- applying pads around the corn area
- wearing larger shoes to comfortably fit your foot without rubbing
- surgery
To avoid corn development, always purchase footwear that fits properly.
What is a bunion?
A bunion is a protrusion of bone or tissue around a
joint. Bunions may occur at the base of the great toe or at the base of
the little toe, and often occur when the joint is stressed over a
period of time. Women are more frequently affected because they may wear
tight, pointed, and confining shoes. Bunions can also be a result of
arthritis which often affects the big toe joint.
Treatment of bunions may vary depending on the pain and deformity. Treatment may include:
- wearing comfortable, well-fitting footwear (particularly shoes that conform to the shape of the foot and do not cause pressure areas)
- surgery (for pain, not for cosmetic purposes)
- applying pads to the affected area
- medication such as ibuprofen
What is Morton's neuroma?
Morton's neuroma is a build-up of benign
(non-cancerous) tissue in the nerves running between the long bones of
the foot. Morton's neuroma occurs when two bones rub together and
squeeze the nerve between them. Most often, neuromas develop between the
bones leading to the third and fourth toes. Morton's neuroma often
causes swelling, tenderness, and pain. If the pain becomes severe, it
may cause tingling, numbness, and burning in the toes. It usually occurs
after standing or walking for a long period of time. Treatment for this
condition may involve rest and/or a change in footwear that does not
restrict the foot. If the problem persists, cortisone injections and/or
surgery may be considered.
What are hammertoes?
A hammertoe is a condition in which the toe
buckles, causing the middle joint of the affected toe to poke out. This
condition is often aggravated by tight-fitting shoes that put pressure
on the hammertoe. Often a corn develops at this site. Treatment for
hammertoes may include:
- applying a toe pad specially positioned over the bony protrusion
- changing your footwear to accommodate the deformed toe
- surgical removal
What is an ankle sprain?
An ankle sprain is an injury to the ligaments in
the ankle. Ligaments are tough bands of elastic tissue that connect
bones to each other. Ankle sprains may occur if the ankle rolls, turns,
or twists beyond its normal range of motion. Ankle sprains may be caused
by awkward foot placement, irregular surfaces, weak muscles, loose
ligaments, or wearing shoes with spiked heels. The symptoms of a sprain
will depend on how severely the ligaments are stretched or torn but
usually include swelling, pain, or bruising. Treatment will depend on
the severity of the sprain and may include:
- resting the ankle
- wrapping the ankle with elastic bandage or tape
- ice pack application (to reduce inflammation)
- elevating the ankle
- gradual return to walking and exercise
- a walking cast (for moderate sprains)
- surgery (for severe sprains)
- physical therapy
What is a foot fracture?
With 26 bones in a single foot, almost any of them
can be broken. Many fractures do not require surgery, or even a cast, as
they will heal on their own with some support. When a foot is
fractured, the site of the fracture usually is painful and swollen. The
site of the fracture will determine the course of treatment, if
necessary, including the following:
- ankle joint fractures
These fractures may be serious and require immediate medical attention. Ankle fractures usually require a cast, and some may require surgery if the bones are too separated or misaligned. - metatarsal bone fractures
Fractures of the metatarsal bones, located in the middle of the foot, often do not require a cast. A stiff-soled shoe may be all that is needed for support as the foot heals. Sometimes, surgery is needed to correct misaligned bones or fractured segments. - sesamoid bone fractures
The sesamoid bones are two small, round bones at the end of the metatarsal bone of the big toe. Usually, padded soles can help relieve pain. However, sometimes, the sesamoid bone may have to be surgically removed. - toe fractures
Fractures of the toes normally can heal with or without a cast.
What is foot pain?
Foot pain can be debilitating to an active
lifestyle. Foot pain can have many sources, from fractures and sprains
to nerve damage. Listed below are three common areas of pain in the foot
and their causes:
- pain in the ball of the foot
Pain in the ball of the foot, located on the bottom of the foot behind the toes, may be caused by nerve or joint damage in that area. In addition, a benign (non-cancerous) growth, such as Morton's neuroma, may cause the pain. Corticosteroid injections and wearing supportive shoe inserts may help relieve the pain. Sometimes, surgery is necessary. - plantar fasciitis
Plantar fasciitis is characterized by severe pain in the heel of the foot, especially when standing up after resting. The condition is due to an overuse injury of the sole surface (plantar) of the foot and results in inflammation of the fascia, a tough, fibrous band of tissue that connects the heel bone to the base of the toes. Plantar fasciitis is more common in women, people who are overweight, people with occupations that require a lot of walking or standing on hard surfaces, people with flat feet, and people with high arches. Walking or running, especially with tight calf muscles, may also cause the condition.
Treatment may include:
- rest
- ice pack applications
- nonsteroidal anti-inflammatory medications
- stretching exercises of the Achilles tendons and plantar fascia
- Achilles tendon injury
The Achilles tendon is the largest tendon in the human body. It connects the calf muscle to the heel bone. However, this tendon is also the most common site of rupture or tendonitis, an inflammation of the tendon due to overuse. Achilles tendonitis is caused by overuse of the tendon and calf muscles. Symptoms may include mild pain after exercise that worsens gradually, stiffness that disappears after the tendon warms up, and swelling. Treatment may include:
- rest
- nonsteroidal anti-inflammatory medications
- supportive devices and/or bandages for the muscle and tendon
- stretching
- massage
- ultrasound
- strengthening exercises
- surgery
