Foot Arch Pain After Exercise

Overview
The arch of the foot is formed by the tarsal and metatarsal bones and is strengthened by ligaments and tendons that enable the foot to correctly support the weight of the body. The underside of the foot is made up of four layers of muscle tissue as well as a length of thick connective tissue called the plantar fascia, which supports the arch. If the surrounding muscles weaken, the plantar fascia will drop and the arch will collapse. If the arch collapses, the whole foot touches the ground, which is known as pes planus or flat feet. Flat feet affect about 15 per cent of Britons. Although usually genetic, the condition may be exacerbated or triggered by poorly fitted shoes or conditions such as arthritis and pregnancy, when sudden changes in shape and weight can alter the body's centre of gravity leading to a weakening of the arches.


Causes
There are many different causes of flat feet, which can be separated into two main categories. The first category, congenital flat foot, is a condition that one is born with or is predisposed to at birth. This type includes the completely asymptomatic, pediatric flexible flat foot-by far the most common form of congenital flat foot. Flexible means that an arch is present until weight is put on the foot, at which time the arch disappears. This foot type is a result of the fact that all people are born with different physical features. Some people have bigger noses than others, just as some people have flatter feet (of course, there is no known correlation between the two). Any alteration in the many building blocks of the foot can influence its shape.

Symptoms
The groups of muscles that support the arch can be divided into two groups. The muscles on the top of the arch start on the front lower leg and help to lift the arch, and the muscles that help pull the arch on the bottom of the foot are located the on back of the lower leg. Muscle injury may be indicated when pain is felt when the foot is fully extended, flexed, or turned in or out. Pain may also be felt when working the foot against resistance. Bruises are the result of a direct-force injury to the body. A bruise can occur to the foot by a variety of causes, such as having your foot stepped on or by stepping on a rock. The tissues that compose the arch do not provide that area of the body much protection. Blows to the foot that result in pain, discoloration, swelling, and changes in how you walk may indicate more serious damage.

Diagnosis
Diagnosis of a plantar plate tear can often be challenging due to the complex nature of the anatomy of the foot. Careful history taking and an examination of the area of pain is required to determine the extent and cause of the tear. If necessary, further investigations such as x-rays or diagnostic ultrasound may be ordered by your podiatrist to help evaluate the severity of the problem.

Non Surgical Treatment
Treatment must be directed to supporting the individual bones and joints which make up the arch, and to aid the arch in its job as a shock absorber. This in turn alleviates the arch pain, and prevents the further collapse of the arch. This is accomplished through the use of either a high quality arch support or custom-made orthotics. These devices support not only the arch, but each individual bone and joint which makes up the arch; and because of the space-age materials used in their construction, allow the arch to become a much more efficient shock absorber. This not only relieves the arch pain, but also prevents it from returning, and keeps the arch from collapsing further.


Surgical Treatment
The procedure involves cutting and shifting the bone, and then performing a tendon transfer. First, the surgeon performs a calcaneal osteotomy, cutting the heel bone and shifting it into the correct position. Second, the surgeon transfers the tendon. Reroute the flexor digitorum to replace the troublesome posterior tibial tendon. Finally, the surgeon typically performs one or more fine-tuning procedures that address the patient?s specific foot deformity. Often, the surgeon will lengthen the Achilles tendon because it is common for the mispositioned foot to cause the Achilles to tighten. Occasionally, to increase the arch, the surgeon performs another osteotomy of one of the bones of the midfoot. Occasionally, to point the foot in a straightforward direction, the surgeon performs another osteotomy of the outside portion of the calcaneus.


Prevention
To prevent arch pain, it is important to build up slowly to your exercise routine while wearing arch supports inside training shoes. By undertaking these simple measures you can prevent the discomfort of arch pain which can otherwise linger for many months. While you allow the foot to recover, it will help to undertake low impact exercises (such as swimming or water aerobics).

Stretching Exercises
Try these simple stretches to assist with relieving pain in your arches. (Note: Stretch slowly and gently. You should feel a moderate pull on the muscle and tendon but no pain. If these stretches are painful, stop and seek further advice from a health professional). STRETCH ONE. Stand at arm?s length from a wall with one foot in front of the other, forward knee bent. Keeping your back leg straight and back heel on the floor, lean into the wall until you feel a stretch in your calf. STRETCH TWO. This time, bend your back leg slightly, and lean into the wall. You should feel a stretch in the lower part of your calf. Hold each stretch for 20 seconds and repeat on each leg, a few times daily.
