The most common cause of arch and heel pain is a condition called plantar fasciitis. This is an inflammation of a thick band of tissue that runs along the arch of your feet from your heel to your toes, and aids in the stabilization of your arch during walking and running. Symptoms involve two areas-the arch, and more commonly, the inside heel area. Severe pain can be present, especially in the morning on arising.

Causes
Having low or no arches is normal for some people. In these cases, flat feet are usually inherited and the feet are fairly flexible. Occasionally, flat feet can be caused by an abnormality that develops in the womb, such as a problem with a joint or where two or more bones are fused together. This is known as tarsal coalition and results in the feet being flat and stiff. Flat feet that develop in later life can be caused by a condition that affects the joints, such as arthritis, or an injury to a muscle, tendon or joint in the foot.
Symptoms
Bones and ligaments work together to form joints, and bones are joined together by ligaments. Strains occur in ligaments. In the arch, there are ligaments that are located at the ends of each bone. These ligaments connect the bones to other bones on both ends and on the sides. Point tenderness and looseness of a joint are indicators of a sprain. Fractures are indicated by point tenderness that may be severe over the area of bone that is affected. There may be a distinguishable lump or gap at the site of the fracture. A rotated toe or forefoot may also be a sign of a fracture.
Diagnosis
The diagnosis of high arch (cavus) foot deformity or Charcot Marie Tooth disease can be made by an orthopedic surgeon in the office. Evaluation includes a thorough history and physical examination as well as imaging studies such as X-rays. The orthopedic surgeon will look at the overall shape, flexibility, and strength of a patient?s foot and ankle to help determine the best treatment. Nerve tests may occasionally need to be performed to help confirm the diagnosis.
Non Surgical Treatment
Rest and icing the swollen area are a good way to practice in-home treatment for mild foot arch pains. Anti inflammatory medications can also be applied to the area. It is important to reduce your activity to avoid worsening the arch pain. Wearing shoes that fit properly is important as well. Make sure to use shoes that are designed with adequate arch support to prevent over pronating. When running, avoid uneven surfaces, as this may contribute to your foot arch pain. Also, orthopedic pads or other padded heel cups and devices can be inserted into shoes to provide support and prevent more strain to the foot.

Surgical Treatment
Fallen arches may occur with deformities of the foot bones. Tarsal coalition is a congenital condition in which the bones of the foot do not separate from one another during development in the womb. A child with tarsal coalition exhibits a rigid flat foot, which can be painful, notes the patient information website eOrthopod. Surgery may prove necessary to separate the bones. Other foot and ankle conditions that cause fallen arches may also require surgery if noninvasive treatments fail to alleviate pain and restore normal function.
Prevention
Drink plenty of water before, during and after your workout. Dehydration is a common cause of muscle cramps, according to MayoClinic.com. If your workouts are long and strenuous, drink a carbohydrate-based electrolyte beverage too. Warm up the muscles of your feet before you work out. A simple exercise is to write the letters of the alphabet with your toes. Perform the warm up with bare feet and exaggerate the movements to challenge your muscles. Wear properly fitted shoes. Visit a sporting goods store and get your feet and arches measured. Ask for help selecting a pair of shoes to fit your workout. For instance, if you play soccer, you need cleats, not running shoes. Take a break. Cramps can be your body's way of telling you you're exercising too much, according to MayoClinic.com. Rest for a few days, then resume exercise and see if you can complete a workout without arch cramps. Stretch. At the end of your workout, perform a few stretching exercises to keep your muscles from tightening and cramping. Sit down, lean over and grasp your toes. Pull the toes toward your body until you feel tension in the arch of your foot. Hold the stretch for 20 to 30 seconds, then repeat on the opposite side. Another easy way to stretch your arch is to put a towel on the floor, curl your toes around it and pull it toward your body.
Stretching Exercises
Stretching your calf and Achilles tendon may also help as a tight Achilles can make your foot overpronate. To stretch your calf and Achilles tendon, step forwards with your left leg and bend it, with your right leg straight and both feet pointing forwards. Push your right heel into the ground while keeping your right leg straight; you should feel the stretch at the back of your right leg, below the knee. Hold the stretch for 15 to 30 seconds and repeat with the opposite leg. Repeat the stretch two to four times on each leg, and repeat the overall exercise three to four times a day.
