Arch pain typically is the term used to describe pain under the arch of the foot. Arch pain indicates inflammation of the tissues within the midfoot and is most commonly caused by plantar fasciitis. Plantar fasciitis is inflammation of the fibrous band of tissue that connects the heel to the toes. Arch pain is most commonly found early in the morning due to the plantar fascia becoming contracted and tight during sleep. Walking or standing for long periods of time can also aggravate the plantar fascia, causing it to become inflamed and irritated. Treatment options include orthotics, anti-inflammatory medications and stretching exercises.

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
Go to a podiatrist at the first sign of symptoms. Besides pain on the bottom of the foot, additional symptoms may include burning sensation in arch, difficulty standing on tiptoes, inflammation, more pain after sleeping or resting, redness, heat, localized pain in the ball of the foot, sharp or shooting pain in the toes, pain that increases when toes are flexed, tingling or numbness in the toes, aching, pain that increases when walking barefoot, pain that increases when walking on hard surfaces, pain the increases when standing (putting weight on your feet) or moving around and decreases when immobile, skin Lesions, it?s important to get a proper diagnosis and treatment plan. Let?s go over the possible causes of the pain.
Diagnosis
The adult acquired flatfoot, secondary to posterior tibial tendon dysfunction, is diagnosed in a number of ways with no single test proven to be totally reliable. The most accurate diagnosis is made by a skilled clinician utilizing observation and hands on evaluation of the foot and ankle. Observation of the foot in a walking examination is most reliable. The affected foot appears more pronated and deformed compared to the unaffected foot. Muscle testing will show a strength deficit. An easy test to perform in the office is the single foot raise.
Non Surgical Treatment
What remedies work best depends on the source of your pain. Stretches help tightened, overused muscles to relax, and exercises help weakened ones to regain the strength they need to hold your foot in its proper place. Prescription orthotics add extra support and help your arch more efficiently distribute weight. Changing your shoes to ones that better cushion and brace your foot also help. Generally flatfoot pain doesn?t require surgery, unless the problem was caused by a torn tendon. You may then need a procedure to repair the damaged tissue and realign your arch.

Surgical Treatment
If you have pain that has not been responsive to other treatments, there is a new non-surgical treatment that was recently approved by the FDA. ESWT (extracorporeal shockwave therapy) uses strong electrohydraulic acoustic (sound) energy that triggers the body?s natural repair mechanism. This treatment method is safe, effective and requires a very short recovery period compared to older surgical techniques.
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
Below are two simple plantar fasciitis stretching exercises to help improve the flexibility of the muscles and tendons around the foot and ankle. Plantar fasciitis stretch taken from The Stretching Handbook. Kneel on one foot and place your body weight over your knee. Keep your heel on the ground and lean forward.

Place your body weight over your knee and slowly move your knee forward. Keep your toes on the ground and arch your foot.
