Sharp Pain In The Arch Of My Feet

Overview

Arch pain occurs with an inflammation of the plantar arch or fascia. It is the thick membrane that covers and supports all the muscles of the sole of the foot from the heel bone to the base of the toes that is called plantar arch. When this membrane pulls excessively (constant strain), pain developes in the arch of the foot or heel.

Foot Arch Pain

Causes

A common cause of foot arch pain is a stress fracture. They tend to occur from repeated overloading of one of the foot bones from activities such as jumping and running especially if you have suddenly increased your activity level. The breaks in the bone may be small but they can be extremely painful. Stress fractures of the metatarsal bones or the navicular can cause anything from mild to severe foot arch pain. The Tibialis Posterior muscle plays a very important role in supporting the medial arch of the foot. Posterior Tibial Tendonitis can occur either through repetitive use e.g. high impact sports such as soccer or tennis, or from an injury e.g. a fall. This causes the tendon to become inflamed or even torn, resulting in pain on bottom of foot. This pain usually gets worse with activity or when standing for long periods. If the problem persists, the inner side of the foot (known as the medial longitudinal arch of the foot) gradually collapses down, causing flat feet. A simple test for this condition is to stand on one leg and rise up onto your tiptoes. If you cannot, it indicates a problem with the Posterior Tibial tendon. Treatment usually consists of rest, ice, exercises, orthotics and physical therapy.

Symptoms

The primary symptom is pain or aching in the arch area. This can be accompanied by inflammation and tenderness. If the pain is caused by the plantar fascia, it is likely to be considerably more severe in the mornings due to the muscles being unused.

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

You may have noticed that one common element in the conservative treatment of all types of flat feet is orthoses. Many companies now manufacture semi-custom orthotic devices that not only improve comfort, but also seek to control abnormal motion of the foot. These over-the-counter inserts, in the $25 to $50 range, are an economical treatment that may help a majority of people. Unfortunately, these semi-custom devices will not fit everyone perfectly, and those of us who differ too much from the average may respond better to custom orthotic devices. Custom inserts are prescribed by your foot and ankle specialist and are made individually from either a physical or computerized impression of your feet. The only drawback of custom orthoses is their cost, ranging anywhere from $300 to $500. Many physicians recommend trying over-the-counter inserts first (and even keep them in stock) as they may save their patients large sums of money.

Surgical Treatment

The soft tissue surgeries usually would include a lengthening of the Achilles tendon, releasing of the plantar fascia as well as tendon transfers. These procedures are usually done in conjunction with bony procedures such as calcaneal osteotomies (to lower the heel bone and get it more under the leg itself), as well as metatarsal osteotomies. These procedures usually involve either cutting or fusion of the bones, and placement of fixation devices to allow the bones to heal. Healing time is usually at least 6-8 weeks and usually the patient must be non-weight bearing during the healing process. These types of surgical corrections are usually reserved for the more difficult, painful and deformed feet. They can require more surgeries down the line. These procedures are usually the last resort after all other modes of treatment have been exhausted (except in children where it is usually best to treat the deformity early). There are many different degrees of high arched feet and these procedures should be left for the more extreme cases. These cases usually require a very high degree of surgical skill and should only be done by those who frequently perform these types of cases.

Stretching Exercises

Ankle evert or strengthening. Lie on your side with your feet hanging off the end of your bed or a weight bench. Bend the toes of the foot that is closer to the ceiling slightly toward your head. This is the starting position. Now raise your toes toward the ceiling while keeping the rest of your leg stationary. Return to the starting position. Reps. 10-15. Now point your toes slightly away from your head. This is the starting position. Raise your toes toward the ceiling. Return to the starting position. Reps. 10-15. Ankle invertor strengthening. Same as above, but do the exercises with the foot that is closer to the floor. Dorsiflexor strengthening. Sit on a desk, table, or counter so that your feet don?t touch the ground. Let your feet dangle comfortably. Bend your foot upward as far as you can comfortably go. Do not let your foot pull inward or outward. Return to the starting position. Reps. 10-15.
