Arch pain is often felt as a burning sensation under the long arch of the foot. There are a number of causes of this, but the most common is plantar fasciitis, but can also be due to the strain of any structure in the arch of the foot.
The normal arch is made up of bones and joints, which are held tightly together, in a precise relationship. When this relationship is subjected to repeated abnormal weight, or the normal weight of a lifetime, the force breaks up this normal relationship, causing bones to shift and joints to buckle. This allows the arch to collapse, and produces pain. The ability of the arch to absorb the shock of each step is reduced, so that continued walking will eventually produce pain in the knee, hip, and lower back. All four of the above categories will eventually cause this to happen. Arch pain can also be a manifestation of heel spur or nerve injury in the heel area. There are also certain types of benign growths that can cause arch pain i.e. Plantar fibromatosis.
Common symptoms of plantar fasciitis include pain in the morning when you first get out of bed, pain and stiffness when you start to walk after sitting for a while, increasing arch or heel pain toward the end of the day, tired feet at the end of the day. Other causes of arch and heel pain include arthritis, infection, fractures and sprains, and even certain systemic diseases. Since there are multiple possible causes, you should see your podiatrist for a thorough evaluation if you are experiencing arch or heel pain that does not respond quickly to early treatment.
To come to a correct diagnosis, your podiatrist will examine your foot by using his or her fingers to look for a lump or stone bruise in the ball of your foot. He or she will examine your foot to look for deformities such as high or low arches, or to see if you have hammertoes. He or she may use x-rays, MRIs (magnetic resource imaging), and CT scans to rule out fractures and damage to ligaments, tendons, and other surrounding tissues. Your doctor will also inquire about your daily activities, symptoms, medical history, and family history. If you spend a lot of time running or jumping, you may be at a higher risk for pain in the bottom of your foot. These diagnostic tests will help your doctor come to a proper diagnosis and create an appropriate treatment plan.
Non Surgical Treatment
In mild cases patients would benefit from custom made semi rigid full length custom made foot orthoses fitted into appropriate supportive footwear, preferably with laces or a velcro straps. In more severe cases patients may require a custom made Arizona lace up ankle brace or a posterior shell Ankle Foot Orthosis. These offer significantly more control and support than the foot orthoses. In severe cases surgery may be required to repair the tibialis posterior tendon and realign the foot and ankle, or fuse the subtalar joint. It is important to note there are many risks involved in having surgery and these must be considered prior to going ahead.
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.
Arch pain occurs when the plantar fascia becomes worn down due to constant strain or excessive exercising. This may be caused by increasing your running or hiking mileage too fast, wearing inadequate footwear, lack of stretching, running on steep hills, standing on your feet for too long and abnormal anatomy such as flat foot. Stretching is an important exercise that should not be overlooked because the tightness or lack of tightness of the joints in the foot can also cause pain in the arch.
Strengthening exercises. Below are two simple strength exercises to help condition the muscles, tendons and joints around the foot and ankle. Plantar Rolling. Place a small tin can or tennis ball under the arch of the affected foot. Slowly move the foot back and forth allowing the tin can or tennis ball to roll around under the arch. This activity will help to stretch, strengthen and massage the affected area. Toe Walking. Stand upright in bare feet and rise up onto the toes and front of the foot. Balance in this position and walk forward in slow, small steps. Maintain an upright, balanced posture, staying as high as possible with each step. Complete three sets of the exercise, with a short break in between sets, for a total of 20 meters.
