The arch functions as a shock absorber for our entire body. Each time we step down, we place up to 5 times our body weight on the foot, depending on whether we are walking, running, or jumping. If there were no shock absorber in the foot, the force of each step would fracture or dislocate the bones of the foot, leg, and lower back. When pain occurs in the arch, it is telling us it is "sick" and cannot function properly. If left untreated, it can cause constant pain throughout the entire foot, and eventually the knee, hip, and lower back.
Arch pain can be caused by several different factors. Tight calf muscles combined with repeated arch collapse on weight bearing, is the most common cause of arch pain.This can then often lead to a condition called plantar fasciitis, which is an inflammation of the connective tissue that connects the heel with the ball of the foot. When the connective tissue in the bottom of the feet gets stretched out too much, plantar fasciitis can result. The inflammation resulting from plantar fasciitis can result in arch pain. Arch pain caused by plantar fasciitis is often worst after long periods of rest, like when you first wake up in the morning. This is because the plantar fascia tightens when you are off your feet. When you wake up in the morning and start walking around, the plantar fascia stretches out again.
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.
A patient is asked to step with full body weight on the symptomatic foot, keeping the unaffected foot off the ground. The patient is then instructed to "raise up on the tip toes" of the affected foot. If the posterior tibial tendon has been attenuated or ruptured, the patient will be unable to lift the heel off the floor and rise onto the toes. In less severe cases, the patient will be able to rise on the toes, but the heel will not be noted to invert as it normally does when we rise onto the toes. X-rays can be helpful but are not diagnostic of the adult acquired flatfoot. Both feet, the symptomatic and asymptomatic - will demonstrate a flatfoot deformity on x-ray. Careful observation may show a greater severity of deformity on the affected side.
Non Surgical Treatment
Use corrective prophylactic measures. Purchase new shoes or replace the insoles of your current shoes. Athletic shoes lose the elastic properties of the soles through usage and age. A good rule of thumb is to replace your shoes every six months, more often if there is heavier usage. The use of after-market insoles can increase energy absorption and add support to the foot. Custom fabricated orthotics or off-the-shelf orthotics may also improve the biomechanics of the foot. Focus on muscle strengthening and flexibility. You may be given exercises to increase the strength and stability of the affected area and to correct muscles that may not be balanced. Exercises to increase flexibility will maintain or improve the length of a muscle. Flexibility helps to make a stronger muscle that is less likely to be injured.
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.
Achilles stretch. Stand with the ball of one foot on a stair. Reach for the step below with your heel until you feel a stretch in the arch of your foot. Hold this position for 15 to 30 seconds and then relax. Repeat 3 times. Balance and reach exercises. Stand next to a chair with your injured leg farther from the chair. The chair will provide support if you need it. Stand on the foot of your injured leg and bend your knee slightly. Try to raise the arch of this foot while keeping your big toe on the floor. Keep your foot in this position. With the hand that is farther away from the chair, reach forward in front of you by bending at the waist. Avoid bending your knee any more as you do this. Repeat this 15 times. To make the exercise more challenging, reach farther in front of you. Do 2 sets of 15. While keeping your arch raised, reach the hand that is farther away from the chair across your body toward the chair. The farther you reach, the more challenging the exercise. Do 2 sets of 15. Towel pickup. With your heel on the ground, pick up a towel with your toes. Release. Repeat 10 to 20 times. When this gets easy, add more resistance by placing a book or small weight on the towel. Resisted ankle plantar flexion. Sit with your injured leg stretched out in front of you. Loop the tubing around the ball of your foot. Hold the ends of the tubing with both hands. Gently press the ball of your foot down and point your toes, stretching the tubing. Return to the starting position. Do 2 sets of 15. Resisted ankle dorsiflexion. Tie a knot in one end of the elastic tubing and shut the knot in a door. Tie a loop in the other end of the tubing and put the foot on your injured side through the loop so that the tubing goes around the top of the foot. Sit facing the door with your injured leg straight out in front of you. Move away from the door until there is tension in the tubing. Keeping your leg straight, pull the top of your foot toward your body, stretching the tubing. Slowly return to the starting position. Do 2 sets of 15. Heel raise. Stand behind a chair or counter with both feet flat on the floor. Using the chair or counter as a support, rise up onto your toes and hold for 5 seconds. Then slowly lower yourself down without holding onto the support. (It's OK to keep holding onto the support if you need to.) When this exercise becomes less painful, try doing this exercise while you are standing on the injured leg only. Repeat 15 times. Do 2 sets of 15. Rest 30 seconds between sets.
