Dealing With Arch Pain

Overview
Each foot contains 26 bones, which form two arches. The longitudinal arch runs the length of the foot, and the transverse arch runs the width. The bones of the arch are primarily held together by the shape with which they fit with each other and by fibrous tissues known as ligaments that serve to hold the bones to each other. The muscles of the foot, along with a tough, sinewy tissue known as the plantar fascia, provide secondary support to the foot. There are also fat pads in the foot to help with weight-bearing and absorbing impact. Arch pain can occur whenever something goes wrong with the function or interaction of any of these structures.


Causes
At the other end of the spectrum, yet within the same category of congenital flat foot, exist several rare, more severe forms of flat foot. These severe conditions include Vertical Talus, Congenital Calcaneal Valgus, and Tarsal Coalitions - all of which are more rigid (no arch with or without weight on the foot) and definitely symptomatic. Luckily, these are much less common, but can usually be identified by specialists at the time of presentation and treated appropriately. The second category, acquired flat foot, develops over time, rather than at birth. Many different factors can contribute to the development of flat feet. These include the types of shoes a child wears, a child's sitting or sleeping positions, compensation for other abnormalities further up the leg, or more severe factors such as rupture of ligaments or tendons in the foot. Very commonly, the reason for flat feet is that the foot is compensating for a tight Achilles tendon. If the Achilles tendon is tight, then it causes the foot to point down, or to plantarflex (as occurs when stepping on the accelerator of your car). Even minimal amounts of plantarflexion can simulate a longer leg on that particular side, assuming that the other foot is in the normal position. The body therefore tries to compensate by pronating, or flattening out the arch, thereby making up for the perceived extra length on the affected side.

Symptoms
Symptoms include pain which is often described as a burning pain radiating into the arch of the foot, heel and sometimes the toes. Pins and needles or numbness may be felt in the sole of the foot. Pain may be worse when running or when standing for long periods of time and often worse at night. The area under the medial malleolus on the inside of the ankle may be tender to touch.

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
Doctors commonly prescribe shoe inserts, or orthotics, to support the arch. These devices make walking and standing more comfortable for a person with fallen arches, reports the American Academy of Orthopaedic Surgeons. Orthotics are typically worn with closed shoes. They are available over-the-counter or can be custom-made.


Surgical Treatment
The main goal of surgery is to reduce pain and improve function. It may also reduce other injuries such as repeated ankle sprains and broken bones. Surgery may be considered if there is no relief with physical therapy, changes in shoewear and/or changes in activity. Some patients will also have tendon problems, ankle weakness and foot fractures. These patients may require other procedures to address related problems. If you have medical problems that make surgery unsafe, any infections or blood vessel disease, cavus foot surgery may not be appropriate. The surgical procedures involved with the correction of the cavus foot are varied. Theses may include correction of the bony deformity, ankle looseness and the muscle imbalances that cause the deformity. The goal is to provide a foot that evenly distributes weight along both inside and outside edges. A variety of incisions may be needed to perform the procedures related to the correction of the cavus foot.


Stretching Exercises
Flexibility is important in preventing injuries. With a simple stretching exercise, you can rehabilitate the muscles of your foot to relieve arch pain and prevent future injuries. This simple exercise by Tammy White and Phyllis Clapis for Relay Health is a good way to strengthen your foot muscles and stretch your plantar fascia. Sit in a chair and cross one foot over your other knee. Grab the base of your toes and pull them back toward your leg until you feel a comfortable stretch. Hold 15 seconds and repeat three times. When you can stand comfortably on your injured foot, you can begin standing to stretch the plantar fascia at the bottom of your foot.
