there are over 300 foot disorders, these are the most common.
The most important thing to remember is that early treatment
can save a lot of pain and expense. This alphabetical list
does not include all foot and ankle problems. For more extensive
information check the American Podiatric Medical Association

Athlete's Foot
Athlete's foot is a skin disease caused by a fungus, usually
occurring between the toes. The fungus most commonly attacks
the feet because shoes create a warm, dark, and humid environment
which encourages fungus growth. The warmth and dampness of
areas around swimming pools, showers, and locker rooms, are
also breeding grounds for fungi. The signs of athlete's foot,
singly or combined, are drying skin, itching scaling, inflammation,
and blisters. Blisters often lead to cracking of the skin.
When blisters break, small raw areas of tissue are exposed,
causing pain and swelling. Itching and burning may increase
as the infection spreads. Athlete's foot may spread to the
soles of the feet and to the toenails. It can be spread to
other parts of the body, notably the groin and underarms.
Bone Spurs
A bone spur is an overgrowth of bone as a result of trauma
or reactive stress of a ligament or tendon. This growth can
cause pain and even restrict motion of a joint, depending
on its location and size. Spurs may also be located under
the toenail plate, causing nail deformity and pain. Surgical
treatment and procedure is based on the size, location, and
symptoms of the bone spur.
Bunions
A bunion is an enlargement of the joint at the base of the
big toe—the metatarsophalangeal (MTP) joint—that
forms when the bone or tissue at the big toe joint moves out
of place. This forces the toe to bend toward the others, causing
an often painful lump of bone on the foot. Since this joint
carries a lot of the body’s weight while walking, bunions
can cause extreme pain if left untreated. The MTP joint itself
may become stiff and sore, making even the wearing of shoes
difficult or impossible.
Bursitis
This is an inflammation of the bursa, a sac of tissue that
protects bony prominences. It is typically treated with conservative
measures.
Calluses
A callous is a build-up of dead skin cells, usually on the
sole of the foot. They are typically painful and are caused
by pressure on bony prominences. They may be pared down for
temporary relief. Other measures are available for long-term
treatment.
Corns
A corn is a thickening of the skin on bony prominences, always
on the toe. They can be treated or removed with surgery, if
necessary.
Forefront Surgery
Many foot problems do not respond to "conservative"
management. Often when pain or deformity persists, forefront
surgery may be appropriate to help alleviate them, or to restore
the function of your foot.
Fungal Nails
Fungal Nails is an infection of the bed and plate underlying
the surface of the nail, and is caused by various types of
fungi, which are commonly found throughout the environment.
When the tiny organisms take hold, the nail may become thicker,
yellowish-brown or darker in color, and foul smelling. The
infection is capable of spreading to other toenails, the skin,
or even the fingernails. The toenails are especially vulnerable
around damp areas where people are likely to be walking barefoot
-- swimming pools, locker rooms, and showers, for example.
Injury to the nail bed may make it more susceptible to all
types of infection, including fungal infection. Those who
suffer chronic diseases, such as diabetes, circulatory problems,
or immune-deficiency conditions, are especially prone to fungal
nails.
Gout
Gout is an extremely painful condition caused by a build-up
of uric acid, typically affecting the big toe joint. But it
can also affect other joints in the body. It is usually treated
with steroids.
Hammertoes
A hammertoe deformity is a contracture of the toe(s), frequently
caused by an imbalance in the tendon or joints of the toes.
Due to the "buckling" effect of the toe(s), hammertoes
may become painful secondary to footwear irritation and pressure.
Corn and callus formation may occur as a hammertoe becomes
more rigid over time, making it difficult to wear shoes. This
deformity may be corrected through a surgical procedure to
realign the toe(s).
Heel Pain
Heel pain is generally the result of faulty biomechanics
(walking gait abnormalities) that place too much stress on
the heel bone and the soft tissues that attach to it. The
stress may also result from injury, or a bruise incurred while
walking, running, or jumping on hard surfaces; wearing poorly
constructed footwear; or being overweight. The heel bone is
the largest of the 26 bones in the human foot, which also
has 33 joints and a network of more than 100 tendons, muscles,
and ligaments. Like all bones, it is subject to outside influences
that can affect its integrity and its ability to keep us on
our feet. Heel pain, sometimes disabling, can occur in the
front, back, or bottom of the heel.
Ingrown Toenails
Ingrown nails, the most common nail impairment, are nails
whose corners or sides dig painfully into the soft tissue
of nail grooves, often leading to irritation, redness, and
swelling. Usually, toenails grow straight out. Sometimes,
however, one or both corners or sides curve and grow into
the flesh. The big toe is usually the victim of this condition,
but other toes can also become affected. Ingrown toenail may
be caused by improperly trimmed nails, heredity, shoe pressure,
or repeated trauma to the feet from normal activities.
Nail Problems
Toenails often serve as barometers of our health; they are
diagnostic tools providing the initial signal of the presence
or onset of systemic diseases. For example, the pitting of
nails and increased nail thickness can be manifestations of
psoriasis. Concavity—nails that are rounded inward instead
of outward—can foretell iron deficiency anemia. Some
nail problems can be conservatively treated with topical or
oral medications while others require partial or total removal
of the nail. Any discoloration or infection should be evaluated.
Neuromas
An irritation of a nerve may produce a neuroma, which is
a benign enlargement of a nerve segment, commonly found between
the third and fourth toes. Several factors may contribute
to the formation of a neuroma. Trauma, arthritis, high-heeled
shoes, or an abnormal bone structure are just some of the
conditions that may cause a neuroma. Symptoms such as burning
or tingling to adjacent toes and even numbness are commonly
seen with this condition. If conservative treatment does not
relieve the symptoms, then surgical treatment may be appropriate.
Orthotics
Orthotics are custom-made shoe inserts, prescribed by a podiatrist,
made to accommodate a foot deformity. They can improve foot
function.
Tendonitis
Tendonitis is an inflammation of the tendon (the end of the
muscle that attaches to the bone). It can be painful and is
treated with rest and ice packs. Occasionally, cortical steroid
injections may be a necessary treatment.
Warts
Warts are one of several soft tissue conditions of the foot
that can be quite painful. They are caused by a virus, which
generally invades the skin through small or invisible cuts
and abrasions. They can appear anywhere on the skin, but,
technically, only those on the sole are properly called plantar
warts. They are often mistaken for corns or calluses—which
are layers of dead skin that build up to protect an area which
is being continuously irritated. The wart, however, is a viral
infection.
