Painful progressive flatfoot, otherwise known as Tibialis Posterior Tendinitis, is caused by inflammation of the tendon of the tibialis posterior. The tendon then becomes inflamed, stretched or suffers a partial or total tear. If left untreated, this condition may lead to severe disability and chronic pain. Some people are predisposed to this condition if they have flatfeet or an abnormal attachment of the tendon to the bones in the midfoot. Nonsteroidal anti-inflammatory medications, ice, physical therapy, supportive taping and bracing, or orthotic devices are the common ways of treating painful progressive flatfoot. Contact your physician before taking any medication. In some cases, a surgical operation may need to be performed to repair the torn or damaged tendon and restore normal function. To prevent reinjury, orthotic devices may be recommended. In severe cases, surgery on the midfoot bones may be necessary to treat the associated flatfoot condition.
Plantar fasciitis, another sports injury detailed on this website, is regularly the cause of foot arch pain or strain. This can arise due to faulty biomechanics in your feet, which alone can also provoke foot arch pains. The most prominent biomechanical difficulties are flat feet and high arches. With flat feet (or overpronation) the arches appear to be almost flattened, causing unevenness by forcing the feet roll inwards in order to maintain balance and support the body's weight. This places inordinate pressure on the plantar fascia and arches. If by contrast you have high arches (instep), the ankle can roll outwards, again causing undue strain on the arches. Too much of this strain can lead to stretching of the plantar fascia and pain in the arches. Other causes include overstretching or otherwise pressuring the arches, for example by exercising with fatigued leg muscles which leave the feet with excessive work to do. You are also particularly at risk if in your 40s or 50s and commencing an intense program of training after a long period of inactivity.
Repetitive exertive activity arch pain is usually sharp, and localized to a specific area, rather than the entire arch. Usually the pain occurs in the area just in front of the heel. It is present when first standing on the foot in the morning, but may decrease once you start walking around, but will, gradually becomes worse with continued walking or running. Swelling may be present. The pain subsides with rest, but stretching the arch while resting may cause the pain to return. Injury pain is constantly present, but worse when standing on the foot. This pain is localized to a specific area, but may radiate out from this area to the entire foot. The pain is sharp, and usually accompanied by swelling and occasionally "black and blue" discolorations. The pain due to the natural aging process is usually dull and aching, or stiff, and can be felt throughout the entire arch area, rather then in just one spot. This pain is present whenever weight bearing, and usually becomes worse with continued walking. The pain gradually subsides when resting, and usually does not return with stretching. Biomechanical defect pain is usually localized to a section of the arch, such as the inner, middle, outer, front, or back of the arch. This pain may be sharp or dull, but is always worse with continued walking.
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
How the pain in the bottom of your foot is treated will depend heavily on the cause of the pain. Diagnosing the pain while it?s in the early stages is important when determining the best treatment options. If the pain is mild to moderate, simple improvements in footwear can help reduce the symptoms. Most patients must use the RICE method for effective treatment. RICE stands for Rest, Ice, Compression, and Elevation. This is a popular treatment used by athletes. It involves resting the foot, icing it for fifteen to twenty minute intervals, compressing the foot with a bandage, and elevating it at least twelve inches above the heart. Ant-inflammatory and pain medications are also sometimes used to treat bottom-of-foot pain. For more serious cases, steroid injections or foot surgery may help reduce pain and swelling and correct the underlying condition (if there is one.) If you suffer from a severe case of plantar fasciitis and non-surgical methods fail, your doctor may recommend cortisone injections to relieve the pain. If cortisone injections fail, your doctor may recommend a surgical procedure that involves cutting and releasing the plantar fascia.
Cavus foot is caused in part by an over-pull of one of the lateral ankle muscles. A release of this tendon can be performed on the outside of the ankle. Additionally, a transfer of this tendon can be performed to help in correcting deformity of the ankle joint. Often patients will have a tightness of their gastrocnemius muscle, one of the main muscles in the calf. This can increase the deformity or prevent a correction from working. It is addressed with a lengthening of a part of the calf muscle or Achilles tendon. This is often performed through one or more small cuts in the back of the leg or ankle. Finally, the plantar fascia may be tight. The plantar fascia is a cord-like structure that runs from the heel to the front part of the foot. Partial or complete plantar fascia release may be done.
Foot and ankle injuries are common in sports, especially running, tennis and soccer. But sports enthusiasts can decrease the risk of injury by taking some precautions. Lightly stretch or better yet, do a slow jog for two to three minutes to warm up the muscles. Don't force the stretch with a "bouncing motion." The amount of time spent on the activity should be increased gradually over a period of weeks to build both muscle strength and mobility. Cross training by participating in different activities can help build the muscles. People whose feet pronate or who have low arches should choose shoes that provide support in both the front of the shoe and under the arch. The heel and heel counter (back of the shoe) should be very stable. Those with a stiffer foot or high arches should choose shoes with more cushion and a softer platform. Use sport-specific shoes. Cross training shoes are an overall good choice; however, it is best to use shoes designed for the sport.
Easy Beginner Version. Start with your bare foot on a flat surface, toes spread out. Place a penny under the ball of your foot and the end of a pen under the middle of your arch (sticking out from the inside of your foot). Activate your arch by flexing your arch muscle. You should feel the muscles on the ball of your foot pushing down on the penny, but your arch shouldn't be pushing down on the pen. These tools help you (1) avoid rolling your foot and (2) avoid pressing down with your toes (as an extra tip, you can slide a business card under your toes before doing the exercise-when you activate your arch, you should be able to slide the business card out easily with your fingers). Do your best to keep your toes relaxed. Advanced Version. Once you're ready to move on, you can try this advanced version. It builds on the above exercise to incorporate full body twisting and balance, helping you to maintain proper arches while you move. Using the same ideas from above, stand on a flat surface in your bare feet with a penny under the ball of your foot and the end of a pen under your arch. This time, stand with your back a few inches away form a wall or a door. Lift your other leg (the one without the penny or pen) and stand on one foot. Use the wall for balance, if necessary. Lift one arm and stretch it across your body until you touch the wall or door on the opposite side, maintaining a straight back. Keep your foot straight and your arch on the penny but above the pen. Your arch will want to follow the movement and roll off, but you will need to activate it to stay stable during the movement. Lift your other arm and stretch it across the opposite side of your body, still keeping your arch in place.
