Plantar fasciitis is a common cause of heel pain in adults. The disorder classically presents with pain that is particularly severe with the first few steps taken in the morning. In general, plantar fasciitis is a self-limited condition. However, symptoms usually resolve more quickly when the interval between the onset of symptoms and the onset of treatment is shorter. Many treatment options exist, including rest, stretching, strengthening, change of shoes, arch supports, orthotics, night splints, anti-inflammatory agents and surgery. Usually, plantar fasciitis can be treated successfully by tailoring treatment to an individual's risk factors and preferences.
The cause of plantar fasciitis is often unclear and may be multifactorial. Because of the high incidence in runners, it is best postulated to be caused by repetitive microtrauma. Possible risk factors include obesity, occupations requiring prolonged standing and weight-bearing, and heel spurs. Other risk factors may be broadly classified as either extrinsic (training errors and equipment) or intrinsic (functional, structural, or degenerative). Training errors are among the major causes of plantar fasciitis. Athletes usually have a history of an increase in distance, intensity, or duration of activity. The addition of speed workouts, plyometrics, and hill workouts are particularly high-risk behaviors for the development of plantar fasciitis. Running indoors on poorly cushioned surfaces is also a risk factor. Appropriate equipment is important. Athletes and others who spend prolonged time on their feet should wear an appropriate shoe type for their foot type and activity. Athletic shoes rapidly lose cushioning properties. Athletes who use shoe-sole repair materials are especially at risk if they do not change shoes often. Athletes who train in lightweight and minimally cushioned shoes (instead of heavier training flats) are also at higher risk of developing plantar fasciitis.
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.
The health care provider will perform a physical exam. This may show tenderness on the bottom of your foot, flat feet or high arches, mild foot swelling or redness, stiffness or tightness of the arch in the bottom of your foot. X-rays may be taken to rule out other problems.
Non Surgical Treatment
Rest until the pain resolves and you are feeling better. For most people with plantar fasciitis it is very difficult to rest as daily routine demands using their feet during the day for work or other activities. By using the painful foot you keep on hurting the plantar fascia, harming the foot and increasing inflammation. Rest as much as you can, reduce unnecessary activities and additional stress on the fascia. Cold therapy like applying ice to the bottom of your foot helps reduce pain and inflammation. Cold therapy can be used all the time until symptoms have resolved. Some patients prefer to roll their foot over an iced cold drink can or bottle taken out of the freezer. Physical therapy Exercises are good plantar fasciitis treatment. Stretching and other physical therapy measures may be used to provide relief. Stretching the plantar fascia is reported in scientific studies to be a very effective treatment technique. Gait analysis will determine if you overpronate or oversupinate. An expert may perform a test of the way you stand and walk to see if you step in a way that puts more stress on the plantar fascia. You can try to change the way you walk and stand according to the experts recommendation as part of your treatment. Exercise the foot muscles to make the muscles stronger. One good exercise is grabbing and lifting up a towel or marbles using your toes. You can do the same exercise without a towel as though you are grasping something with the toes of each foot. Another good exercise is walking as tall as you can on your toes and on the balls of your feet. Stretching the plantar fascia and the calf muscles several times a day is an important part of the treatment and prevention. There are many stretching exercises for the plantar fascia and the calf muscles that you can find. Long term treatment should not focus in reduction of pain and inflammation alone. This is a passive short term relief treatment. Stretching exercises results are longer and more flexible foot movement which can prevent another fascia injury. Plantar fasciitis taping technique can assist the foot getting rest and help it from getting injured again. Athletic tape is applied in strips on the skin on the bottom of the foot supporting the plantar fascia. The tape restricts the movement of the foot so the fascia can not be injured again. Taping supports the foot by putting the tired foot muscles and tendons in a physiologically more relaxed position. A night splint is worn during sleep. It holds the calf muscles and plantar fascia in a stretched position. Night splint treatment lets the fascia heal in a stretched position so it will not get bruised again when waking up and stretching it again while walking. Orthotics or inserts that your doctor may prescribe or custom made arch supports (orthotics) plantar fascia orthotic. help to distribute the pressure on your feet more evenly. Arch Support gives a little raise to the arch assisting the plantar fascia. There are also over-the-counter inserts that are used for arch support and heel cushioning. Heel cups and cradles provide extra comfort and cushion the heel. They reduce shock placed on the foot during everyday activities like Shock absorbers. Anti-inflammatory or Pain medication that a clinician may recommend can be a plantar fasciitis treatment. Non-steroidal anti-inflammatory drugs such as ibuprofen can reduce swelling and relieve pain. However, these medications may have many side effects and it is important to consider the potential risks and benefits. These medications may relieve the pain and inflammation but will not cure the fascia. Lose weight as much as you can. Extra weight puts more stress on your plantar fascia. Platelet Rich Plasma or PRP therapy, is a procedure which involves an injection of special plasma, made out of the patients own blood, to the injured area. Platelets are special blood components that have a major role in the body ability to heal itself. Blood is taken from the patient and separated into its components. The platelet rich part of the blood is than taken and injected into the injured area - in our case to the bottom of the foot. The special plasma helps the foot recovery process. The procedure is actually maximizing the body's natural healing response of the treated area. Extracorporeal shock wave therapy is a procedure which sound waves are targeted at the area of heel pain to encourage healing. It is mostly used for chronic plantar fasciitis which does not respond to conservative treatments. This procedure has many possible side effects like bruising, swelling, pain or numbness and has not proved to be consistently effective. Corticosteroid injection (or cortisone shots) into the painful area may provide relief in severe cases. This kind of medication is very efficient in inflammation reduction. Corticosteroid injections usually provide short-term relief from plantar fasciitis pain. Symptom relief from the corticosteroid injection lasts for 3 to 6 weeks, but the effect often deteriorates and symptoms return. Botox Injections (botulinum toxin) are used to relieve the pain of plantar fasciitis, assist foot function recovery and the ability to walk better. Although the use of Botox injections as heel pain treatment is relatively new, there are a number of medical studies that show significant good results.
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.
