    Toe Pain

    Corns and Calluses
    Corns and calluses are thickened layers of skin that are caused by irritation. The skin is usually cone-shaped and has a knobby core that points in. This core can put pressure on the thin skin under it and cause sharp pain. Corns can develop on top of or between your toes. Soft corns develop between your toes, where they are kept flexible by the moisture from sweat. Calluses develop on the bottom of your foot. Corns and calluses develop as a result of friction from the toes rubbing together or against the shoe.

    Corns are a result of:
    • Shoes, socks, or stockings that fit too tightly around the toes
    • Pressure on the toes from high-heeled shoes
    • Deformed and crooked toes
    Calluses are a result of:
    • Poorly fitting shoes
    • Walking regularly on hard surfaces
    • Flat feet
    Note: If you have diabetes, having calluses is a strong sign of future ulceration, particularly if you have a history of foot ulcers. Contact your doctor.
    Bursitis of the Toe
    Bursitis is an inflammation of the fluid filled sacs that protect your toe joints, particularly the big toe. It often occurs as a result of irritation from rubbing.
    Ingrown Toenails
    Ingrown toenails can occur on any toe. They are most common on the big toe. They can develop when tight-fitting or narrow shoes put too much pressure on the outside of your big toe. This forces the nail to grow into the flesh of your toe. Incorrect toenail trimming can also add to the risk of developing an ingrown toenail. Other conditions that can lead to ingrown toenails include:
    • Injury to the toe
    • Abnormalities in the structure of the foot
    • Repeated impact on the toenail from the shoe during high-impact exercise
    Bunions
    A bunion is a painful swelling. It usually occurs at the head of one of the long bones (metatarsal bones) of the big or little toe. These extend from the arch of the foot and connect to the toes. A bunion begins to form when the big or little toe is forced in toward the rest of the toes. This causes the head of the metatarsal bone to stick out and rub against the side of your shoe. The tissue under it becomes inflamed. A painful swelling forms. Bone growth may occur at the site of irritation. The toe grows towards the rest of your toes at an increasing angle.

    Bunions can be caused by a number of conditions:
    • Narrow high-heeled shoes with pointed toes, which can put great pressure on the front of your foot
    • Injury in the joint
    • Genetics, which may play a role some cases
    Hammertoes
    A hammertoe is a permanent deformity of your toe joint. With hammertoe, your toe bends up slightly and then curls downward, resting on its tip. When forced into this position long enough, the tendons of your toe contract and it stiffens into a hammer, or claw-like, shape.

    A hammertoe is most common in the second toe. However, it may develop in any or all of your three middle toes if they are pushed forward in a shoe and do not have enough room to lie flat.
    Hammer toes are often caused by wearing shoes that are too short.

    Forefoot Pain (Front of the Foot)

    Interdigital (Between the Toes) Neuromas
    Neuromas occur when a nerve, or the tissue surrounding the nerve, becomes enlarged and inflamed. Symptoms are a burning or tingling sensation and cramping in the front of your foot. This condition can be caused by:
    • Tight, poorly fitting shoes
    • Injury
    • Arthritis
    • Abnormal bone structure
    Morton's neuroma is the most common neuroma of the foot. It develops when the metatarsal bones in the middle toes (foot bones that lead to the toes) pinch the nerve that runs between them.
    Stress Fracture
    A stress fracture in your foot usually occurs in one of the five metatarsal bones (mostly the second or third). These fractures are caused by overuse during strenuous exercise, particularly running and other high-impact aerobic sports.
    Sesamoiditis
    Sesamoiditis is a condition involving the sesamoid bones. These are small bones under the head of the first metatarsal bone (the bone that leads to the big toe). The sesamoid bones carry a great amount of weight. The bones and tissue around it can become inflamed and irritated. Sesamoiditis injuries are common among people who do high-impact activities, such as ballet dancing, running, and aerobic exercise.
    Metatarsalgia
    When a cause cannot be determined, any pain on the ball of the foot is generally referred to as metatarsalgia . It is most likely caused by poor footwear or by high-impact activities. People with a high arched foot are more likely to develop metatarsalgia.

    Midfoot Pain

    Tarsal Tunnel Syndrome
    Tarsal tunnel syndrome results from compression of a nerve that runs through a narrow passage behind your inner anklebone down to your heel. It may be caused by injury to your ankle, such as a sprain or fracture. It may also be caused by a growth that presses against the nerve.
    Excessive Pronation
    Pronation is the normal motion that allows your foot to adapt to uneven walking surfaces and to absorb shock. When you have too much pronation, your foot turns outward. This flattens your arch. It also stretches and pulls the fascia. It can cause foot pain. It can also affect the way you walk and lead to problems in the hip, knee, and lower back.

    Heel Pain

    The heel is the largest bone in the foot. Heel pain is the most common foot problem. It affects two million Americans every year. It can occur in the front, back, or bottom of the heel.
    Plantar Fasciitis
    Plantar fasciitis occurs from small tears and inflammation in the plantar fascia. The plantar fascia is a ligament-like structure that stretches from the heel to the ball of your foot. It supports the arch of your foot and helps to serve as a shock absorber.

    Plantar fasciitis is usually a result of overuse during high-impact exercise and sports, especially running. Because the condition often occurs in only one foot, factors other than overuse may be responsible in some cases. Other factors that may increase the rise of this injury include obesity, tight calf muscles, poorly fitting shoes, or an uneven stride.
    Pain is often mainly around the undersurface of the heel. It often spreads to your arch. The condition can be temporary. It may become chronic if you ignore it. Resting usually provides relief. The pain may return.
    Heel Spurs
    Heel spurs are bony growths that stick out from the bottom of the heel bone. They are parallel to the ground. The spur occurs where the plantar fascia attaches. The pain in that area is due to irritation of the attachment. There is a nerve that runs close to this area and may contribute to the pain which occurs. There are many people with heel spurs who have no symptoms at all.
    Haglund's Deformity (Pump Bump)
    Haglund's deformity is a bony growth on the back of the heel bone. It irritates the bursa and the skin behind the heel bone. It is commonly called a "pump bump." It develops when the back of your shoe repeatedly rubs against the back of the heel. This irritates the bursa and skin that is above the bone.
    Achilles Tendinopathy
    Achilles tendinopathy is degeneration of the tendon that connects your calf muscles to your heel bone. There are two common types of tendinopathy: tendinosis and tendinitis. Tendinitis is an inflammation of the tendon. Although the term tendinitis is used more often, tendinopathies are more likely to be a tendinosis, with no inflammation. The tendon suffers excessive stress and internal injury. A small area undergoes degeneration. Small internal tears may develop. Achilles tendinopathy occurs mostly in people who do high-impact exercise, particularly running, racquetball, and tennis. People with calf muscle tightness are more at risk.
    Stress Fracture
    A stress fracture can occur in the heel. It is caused by overuse during strenuous exercise, particularly running and high-impact aerobics. Stress fractures are common in military training.

    Arch and Bottom-of-the-Foot Pain

    Flat Foot
    Flat foot is a defect of your foot that eliminates the arch. The condition is most often inherited. Arches, however, can also “fall” in adulthood. This condition is sometimes referred to as posterior tibial tendon dysfunction (PTTD). This occurs most often in women over 50, but it can occur in anyone. Overall, normally occurring flat feet in adults do not cause many functional problems. Many great athletes have done very well with this condition.
    Abnormally High Arches
    An overly high arch (cavus foot) can cause problems. The cavus foot is much less common than the flat foot.
