Plantar fasciitis is the most common cause of pain on the bottom of the heel. Approximately 2 million patients are treated for this condition every year. Plantar fasciitis occurs when the strong band of tissue that supports the arch of your foot becomes irritated and inflamed. The plantar fascia is a long, thin ligament that lies directly beneath the skin on the bottom of your foot. It connects the heel to the front of your foot, and supports the arch of your foot.
Your plantar fascia (fay-sha) supports the arch of your foot as you run or walk. It is a thick, inelastic, fibrous band that starts in your heel, runs along the bottom of your foot, and spreads out to your toes. Plantar fasciitis is an inflammation of this fibrous band. If you are female or have a job that requires a lot of walking or standing on hard surfaces you are more at risk for plantar fasciitis. Additional causes include Being overweight, Having flat feet or high arches, Wearing shoes with poor support, Walking or running for exercise, Tight calf muscles that limit how far you can flex your ankles, Running on soft terrain, Increase in activity level, Genetic predisposition.
Plantar fasciosis is characterized by pain at the bottom of the heel with weight bearing, particularly when first arising in the morning; pain usually abates within 5 to 10 min, only to return later in the day. It is often worse when pushing off of the heel (the propulsive phase of gait) and after periods of rest. Acute, severe heel pain, especially with mild local puffiness, may indicate an acute fascial tear. Some patients describe burning or sticking pain along the plantar medial border of the foot when walking.
Your doctor will check your feet and watch you stand and walk. He or she will also ask questions about your past health, including what illnesses or injuries you have had. Your symptoms, such as where the pain is and what time of day your foot hurts most. How active you are and what types of physical activity you do. Your doctor may take an X-ray of your foot if he or she suspects a problem with the bones of your foot, such as a stress fracture.
Non Surgical Treatment
First check your shoes for too much midfoot flexibility and check your training for changes. A detailed evaluation of changes in your training is necessary. You should start with what is called "relative rest" which means a decrease in workout intensity, duration of session and decrease in the number of sessions per week. The most important part of self treatment for this condition is being sure that your shoes offer sufficient stability and are optimal in controlling the forces that contribute to plantar fasciitis and heel spurs. Check your running shoes to make sure that they are not excessively worn. They should bend only at the ball of the foot, where your toes attach to the foot. This is vital! Avoid any shoe that bends in the center of the arch or behind the ball of the foot. It offers insufficient support and will stress your plantar fascia. The human foot was not designed to bend here and neither should a shoe be designed to do this. You should also be doing gentle calf stretching exercises. This will reduce stress on the plantar fascia in two ways. The first manner in which a relaxation of the tension in the calf muscles can help heel pain is that it will reduce the direct pull backwards on the heel bone (calcaneus). The second reason is a little bit more complicated, but essentially it is that a tight achilles tendon and calf muscles causes the rearfoot to move in a manner that causes over pronation as your leg and body move forward over your foot. So go ahead and gently stretch the calf muscle by doing the runner's wall leaning stretch. To strengthen the muscles in your arch toe curls or "doming" can be done. Toe curls may be done by placing a towel on a kitchen floor and then curling your toes to pull the towel towards you. This exercise may also be done without the towel against the resistance of the floor.
Surgery for plantar fasciitis can be very successful in the right patients. While there are potential complications, about 70-80% of patients will find relief after plantar fascia release surgery. This may not be perfect, but if plantar fasciitis has been slowing you down for a year or more, it may well be worth these potential risks of surgery. New surgical techniques allow surgery to release the plantar fascia to be performed through small incisions using a tiny camera to locate and cut the plantar fascia. This procedure is called an endoscopic plantar fascia release. Some surgeons are concerned that the endoscopic plantar fascia release procedure increases the risk of damage to the small nerves of the foot. While there is no definitive answer that this endoscopic plantar fascia release is better or worse than a traditional plantar fascia release, most surgeons still prefer the traditional approach.
In one exercise, you lean forward against a wall with one knee straight and heel on the ground. Your other knee is bent. Your heel cord and foot arch stretch as you lean. Hold for 10 seconds, relax and straighten up. Repeat 20 times for each sore heel. It is important to keep the knee fully extended on the side being stretched. In another exercise, you lean forward onto a countertop, spreading your feet apart with one foot in front of the other. Flex your knees and squat down, keeping your heels on the ground as long as possible. Your heel cords and foot arches will stretch as the heels come up in the stretch. Hold for 10 seconds, relax and straighten up. Repeat 20 times. About 90 percent of people with plantar fasciitis improve significantly after two months of initial treatment. You may be advised to use shoes with shock-absorbing soles or fitted with an off-the-shelf shoe insert device like a rubber heel pad. Your foot may be taped into a specific position. If your plantar fasciitis continues after a few months of conservative treatment, your doctor may inject your heel with steroidal anti-inflammatory medication. If you still have symptoms, you may need to wear a walking cast for two to three weeks or a positional splint when you sleep. In a few cases, surgery is needed for chronically contracted tissue.
