Plantar fasciitis is an inflammation of the structures (of the plantar fascia) on the sole of the foot. The inflammation is caused by excess pressure on the structures on the sole of the foot. The plantar fascia becomes inflamed and tiny rips can occur where it attaches into the inside of the heel bone. It tends to be most painful first thing in the morning, or when standing up after sitting for a while. The area becomes inflamed and swollen, and it is the increase in fluid to the area that accumulates when weight is taken off the area, that then causes the pain on standing. Plantar Fasciitis usually starts gradually with pain on standing after rest. Pain is usually located under the heel or to the inside of the heel. Pain is usually at its worst on standing first thing in the morning. The pain will begin to ease once you get moving. Pain in the early stages tends to occur after activity rather than during activity. As plantar fasciitis continues the pain can become more constant and can then start to affect the way you walk.
Plantar fasciitis is the most common cause of heel pain, accounting for around four out of five cases. Plantar fasciitis is when the thick band of tissue that connects the heel bone with the rest of the foot (the plantar fascia) becomes damaged and thickened. Damage to the plantar fascia is thought to occur following sudden damage, for example, damaging your heel while jogging, running or dancing; this type of damage usually affects younger people who are physically active, gradual wear and tear of the tissues that make up the plantar fascia - this usually affects adults who are 40 years of age or over. You are at an increased risk of gradual wear and tear damaging your plantar fasciitis if you are overweight or obese, if you have a body mass index (BMI) of 30 or over, you are considered to be obese, have a job that involves spending long periods of time standing, wear flat-soled shoes, such as sandals or flip flops. Less common causes of heel pain are a stress fracture. A stress fracture can occur if your heel bone is damaged during an injury. Fat pad atrophy. Fat pad atrophy is where the layer of fat that lies under the heel bone, known as the fat pad, starts to waste away due to too much strain being placed on the pad. Women who wear high-heeled shoes for many years have an increased risk of developing fat pad atrophy. Bursitis. Bursitis is inflammation of one or more bursa (small fluid-filled sacs under the skin, usually found over the joints and between tendons and bones). It's possible to develop bursitis anywhere inside the body, not just in the foot. Tarsal tunnel syndrome. The nerves in the sole of your foot pass through a small tunnel on the inside of the ankle joint, known as the tarsal tunnel. If a cyst forms or the tunnel is damaged, the nerves can become compressed (squashed). This can cause pain anywhere along the nerve, including beneath your heel. Sever's disease. Sever's disease is a common cause of heel pain in children. It's caused by the muscles and tendons of the hamstrings and calves stretching and tightening in response to growth spurts. The stretching of the calf muscle pulls on the Achilles tendon. This pulls on the growing area of bone at the back of the heel (growth plate), causing pain in the heel. The pain is further aggravated by activities such as football and gymnastics. The pain often develops at the side of the heel, but can also be felt under the heel. Calf and hamstring stretches and, if necessary, heel pads are usually effective treatments for Sever's disease. Bone spurs. Bone spurs are an excess growth of bone that forms on a normal bone. Bone spurs can develop on the heel (a heel spur) and are more common in people with heel pain. However, they can also occur in people without heel pain. A heel spur does not cause heel pain.
Patients experience intense sharp pain with the first few steps in the morning or following long periods of having no weight on the foot. The pain can also be aggravated by prolonged standing or sitting. The pain is usually experienced on the plantar surface of the foot at the anterior aspect of the heel where the plantar fascia ligament inserts into the calcaneus. It may radiate proximally in severe cases. Some patients may limp or prefer to walk on their toes. Alternative causes of heel pain include fat pad atrophy, plantar warts and foreign body.
Most cases of plantar fasciitis are diagnosed by a health care provider who listens carefully to your description of symptoms. During an examination of your feet, your health care provider will have to press on the bottom of your feet, the area most likely to be painful in plantar fasciitis. Because the pain of plantar fasciitis has unique characteristics, pain upon rising, improvement after walking for several minutes, pain produced by pressure applied in a specific location on your foot but not with pressure in other areas, your health care provider will probably feel comfortable making the diagnosis based on your symptoms and a physical examination. Your health care provider may suggest that you have an X-ray of your foot to verify that there is no stress fracture causing your pain.
Non Surgical Treatment
Your health care provider will often recommend these steps first Acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) to reduce pain and inflammation. Heel and foot stretching exercises. Night splints to wear while sleeping to stretch the foot. Resting as much as possible for at least a week. Wearing shoes with good support and cushions. Other steps to relieve pain include aply ice to the painful area. Do this at least twice a day for 10 - 15 minutes, more often in the first couple of days. Try wearing a heel cup, felt pads in the heel area, or shoe inserts. Use night splints to stretch the injured fascia and allow it to heal. If these treatments do not work, your health care provider may recommend waring a boot cast, which looks like a ski boot, for 3 - 6 weeks. It can be removed for bathing. Custom-made shoe inserts (orthotics). Steroid shots or injections into the heel. Smetimes, foot surgery is needed.
In unusual cases, surgical intervention is necessary for relief of pain. These should only be employed after non-surgical efforts have been used without relief. Generally, such surgical procedures may be completed on an outpatient basis in less than one hour, using local anesthesia or minimal sedation administrated by a trained anesthesiologist. In such cases, the surgeon may remove or release the injured and inflamed fascia, after a small incision is made in the heel. A surgical procedure may also be undertaken to remove bone spurs, sometimes as part of the same surgery addressing the damaged tissue. A cast may be used to immobilize the foot following surgery and crutches provided in order to allow greater mobility while keeping weight off the recovering foot during healing. After removal of the cast, several weeks of physical therapy can be used to speed recovery, reduce swelling and restore flexibility.
Stretching exercises for your foot are important. Do the stretches shown here at least twice a day. Don't bounce when you stretch. Plantar fascia stretch. To do the plantar fascia stretch, stand straight with your hands against a wall and your injured leg slightly behind your other leg. Keeping your heels flat on the floor, slowly bend both knees. You should feel the stretch in the lower part of your leg. Hold the stretch for 10 to 15 seconds. Repeat the stretch 6 to 8 times. Calf stretch. Stand with your hands against a wall and your injured leg behind your other leg. With your injured leg straight, your heel flat on the floor and your foot pointed straight ahead, lean slowly forward, bending the other leg. You should feel the stretch in the middle of your calf. Hold the stretch for 10 to 15 seconds. Repeat the stretch 6 to 8 times. Other exercises. You can also strengthen your leg muscles by standing on the ball of your foot at the edge of a step and raising up as high as possible on your toes. Relax between toe raises and let your heel fall a little lower than the edge of the step. It's also helpful to strengthen the foot by grabbing a towel with your toes as if you are going to pick up the towel with your foot. Repeat this exercise several times a day.
