Foot Arch Pain When Running

Overview
Many people have pain in the base of their foot. This could be due to overuse of one of many different structures in your foot. Common examples are sesamoiditis (inflammation of structures surrounding two small bones under the big toe joint) and plantar fasciitis (overuse of a ligament-like structure that runs underneath the length of the foot). Pain on standing first thing in the morning is a classic symptom of plantar fasciitis. It is one of the most common problems experienced by runners, accounting for about 10 per cent of running injuries. It is also common among middle-aged people, particularly if they are overweight. It often starts with low-grade pain in the arch or heel of the foot and can get worse over weeks or months.


Causes
Flat feet are a common condition. The condition is normal in infants and toddlers. Flat feet occur because the tissues holding the joints in the foot together (called tendons) are loose. The tissues tighten and form an arch as children grow older. This will take place by the time the child is 2 or 3 years old. Most people have normal arches by the time they are adults. However, the arch may never form in some people. Aging, injuries, or illness may harm the tendons and cause flat feet to develop in a person who has already formed arches. This type of flat foot may occur only on one side. Rarely, painful flat feet in children may be caused by a condition in which two or more of the bones in the foot grow or fuse together. This condition is called tarsal coalition.

Symptoms
The majority of children and adults with flexible flatfeet never have symptoms. However, their toes may tend to point outward as they walk, a condition called out-toeing. A person who develops symptoms usually complains of tired, aching feet, especially after prolonged standing or walking. Symptoms of rigid flatfoot vary depending on the cause of the foot problem.

Diagnosis
Your doctor may order imaging tests to help make sure your heel pain is caused by plantar fasciitis and not another problem. X-rays provide clear images of bones. They are useful in ruling out other causes of heel pain, such as fractures or arthritis. Heel spurs can be seen on an x-ray. Other imaging tests, such as magnetic resonance imaging (MRI) and ultrasound, are not routinely used to diagnose plantar fasciitis. They are rarely ordered. An MRI scan may be used if the heel pain is not relieved by initial treatment methods.

Non Surgical Treatment
The adult acquired flatfoot is best treated early. There is no recommended home treatment other than the general avoidance of prolonged weightbearing in non-supportive footwear until the patient can be seen in the office of the foot and ankle specialist. In Stage I, the inflammation and tendon injury will respond to rest, protected ambulation in a cast, as well as anti-inflammatory therapy. Follow-up treatment with custom-molded foot orthoses and properly designed athletic or orthopedic footwear are critical to maintain stability of the foot and ankle after initial symptoms have been calmed. Once the tendon has been stretched, the foot will become deformed and visibly rolled into a pronated position at the ankle. Non-surgical treatment has a significantly lower chance of success. Total immobilization in a cast or Camwalker may calm down symptoms and arrest progression of the deformity in a smaller percentage of patients. Usually, long-term use of a brace known as an ankle foot orthosis is required to stop progression of the deformity without surgery.


Surgical Treatment
With flat feet, there is a tendon on the inside of the foot than can often become weakened, injured, split and/or ruptured. This tendon, is called the posterior tibial tendon, and is the main arch supporting tendon. Obviously damage to this tendon can cause collapse of the arch. Some people have genetically inefficient tendon, and tends to be the case in younger people. In mild cases, such as tendon splits, the posterior tibial tendon can be repaired to restore its strength. Acute incontinuity of the tendon can be primarily repaired. Often the posterior tibial tendon is augmented with a tendon transfer of an adjacent tendon to provide both strength and continuity. In any tendon repair, advanced or retensioning of the tendon is performed. In most flat foot surgery a tendon augmentation is often combined with other boney procedures to restore structure and balance to the foot.


Prevention
Stretch and strengthen important muscles in your feet, ankles and legs in order to guard against future strain. Make sure to acquire suitable arch supports and inserts if necessary, and that your shoes are shock absorbent and in good condition. Wearing tattered shoes provides no protection, and runners should replace their footwear before exceeding 500 miles of usage. Athletes new to arch supports should gradually build their training routine, allowing their feet to become accustomed to a new stance.

Stretching Exercises
Achilles stretch. Stand with the ball of one foot on a stair. Reach for the step below with your heel until you feel a stretch in the arch of your foot. Hold this position for 15 to 30 seconds and then relax. Repeat 3 times. Balance and reach exercises. Stand next to a chair with your injured leg farther from the chair. The chair will provide support if you need it. Stand on the foot of your injured leg and bend your knee slightly. Try to raise the arch of this foot while keeping your big toe on the floor. Keep your foot in this position. With the hand that is farther away from the chair, reach forward in front of you by bending at the waist. Avoid bending your knee any more as you do this. Repeat this 15 times. To make the exercise more challenging, reach farther in front of you. Do 2 sets of 15. While keeping your arch raised, reach the hand that is farther away from the chair across your body toward the chair. The farther you reach, the more challenging the exercise. Do 2 sets of 15. Towel pickup. With your heel on the ground, pick up a towel with your toes. Release. Repeat 10 to 20 times. When this gets easy, add more resistance by placing a book or small weight on the towel. Resisted ankle plantar flexion. Sit with your injured leg stretched out in front of you. Loop the tubing around the ball of your foot. Hold the ends of the tubing with both hands. Gently press the ball of your foot down and point your toes, stretching the tubing. Return to the starting position. Do 2 sets of 15. Resisted ankle dorsiflexion. Tie a knot in one end of the elastic tubing and shut the knot in a door. Tie a loop in the other end of the tubing and put the foot on your injured side through the loop so that the tubing goes around the top of the foot. Sit facing the door with your injured leg straight out in front of you. Move away from the door until there is tension in the tubing. Keeping your leg straight, pull the top of your foot toward your body, stretching the tubing. Slowly return to the starting position. Do 2 sets of 15. Heel raise. Stand behind a chair or counter with both feet flat on the floor. Using the chair or counter as a support, rise up onto your toes and hold for 5 seconds. Then slowly lower yourself down without holding onto the support. (It's OK to keep holding onto the support if you need to.) When this exercise becomes less painful, try doing this exercise while you are standing on the injured leg only. Repeat 15 times. Do 2 sets of 15. Rest 30 seconds between sets.
