Plantar fasciitis is one of the most common explanations of heel pain. It is caused by inflammation to the thick band that connects the toes to the heel bone, called the plantar fascia, which runs across the bottom of your foot. The condition is most commonly seen in runners, pregnant women, overweight people, and individuals who wear inadequately supporting shoes. Plantar fasciitis typically affects people between the ages of 40 and 70.
Plantar fasciitis is caused by straining the ligament that supports your arch. Repeated strain can cause tiny tears in the ligament. These can lead to pain and swelling. This is more likely to happen if your feet roll inward too much when you walk ( excessive pronation ). You have high arches or flat feet. You walk, stand, or run for long periods of time, especially on hard surfaces. You are overweight. You wear shoes that don’t fit well or are worn out. You have tight Achilles tendons or calf muscles.
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.
Plantar fasciitis is usually diagnosed by your physiotherapist or sports doctor based on your symptoms, history and clinical examination. After confirming your plantar fasciitis they will investigate WHY you are likely to be predisposed to plantar fasciitis and develop a treatment plan to decrease your chance of future bouts. X-rays may show calcification within the plantar fascia or at its insertion into the calcaneus, which is known as a calcaneal or heel spur. Ultrasound scans and MRI are used to identify any plantar fasciitis tears, inflammation or calcification. Pathology tests (including screening for HLA B27 antigen) may identify spondyloarthritis, which can cause symptoms similar to plantar fasciitis.
Non Surgical Treatment
Treatment of plantar fasciitis begins with first-line strategies, which you can begin at home. Stretching exercises. Exercises that stretch out the calf muscles help ease pain and assist with recovery. Avoid going barefoot. When you walk without shoes, you put undue strain and stress on your plantar fascia. Ice. Putting an ice pack on your heel for 20 minutes several times a day helps reduce inflammation. Place a thin towel between the ice and your heel,do not apply ice directly to the skin. Limit activities. Cut down on extended physical activities to give your heel a rest. Shoe modifications. Wearing supportive shoes that have good arch support and a slightly raised heel reduces stress on the plantar fascia. Medications. Oral nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, may be recommended to reduce pain and inflammation. If you still have pain after several weeks, see your foot and ankle surgeon, who may add one or more of these treatment approaches. Padding and strapping. Placing pads in the shoe softens the impact of walking. Strapping helps support the foot and reduce strain on the fascia. Orthotic devices. Custom orthotic devices that fit into your shoe help correct the underlying structural abnormalities causing the plantar fasciitis. Injection therapy. In some cases, corticosteroid injections are used to help reduce the inflammation and relieve pain. Removable walking cast. A removable walking cast may be used to keep your foot immobile for a few weeks to allow it to rest and heal. Night splint. Wearing a night splint allows you to maintain an extended stretch of the plantar fascia while sleeping. This may help reduce the morning pain experienced by some patients. Physical therapy. Exercises and other physical therapy measures may be used to help provide relief.
The most dramatic therapy, used only in cases where pain is very severe, is surgery. The plantar fascia can be partially detached from the heel bone, but the arch of the foot is weakened and full function may be lost. Another surgery involves lengthening the calf muscle, a process called gastrocnemius recession. If you ignore the condition, you can develop chronic heel pain. This can change the way you walk and cause injury to your legs, knees, hips and back. Steroid injections and some other treatments can weaken the plantar fascia ligament and cause potential rupture of the ligament. Surgery carries the risks of bleeding, infection, and reactions to anesthesia. Plantar fascia detachment can also cause changes in your foot and nerve damage. Gastrocnemius resection can also cause nerve damage.
Make sure you wear appropriate supportive shoes. Don’t over-train in sports. Make sure you warm up, cool down and undertake an exercise regime that helps maintain flexibility. Manage your weight, obesity is a factor in causing plantar fasciitis. Avoid walking and running on hard surfaces if you are prone to pain. You should follow the recognized management protocol – RICED-rest, ice, compression, elevation and diagnosis. Rest, keep off the injured ankle as much as possible. Ice, applied for 20 minutes at a time every hour as long as swelling persists. Compression, support the ankle and foot with a firmly (not tightly) wrapped elastic bandage. Elevation, keep foot above heart level to minimize bruising and swelling. Diagnosis, Consult a medical professional (such as a Podiatrist or doctor) especially if you are worried about the injury, or if the pain or swelling gets worse. If the pain or swelling has not gone down significantly within 48 hours, also seek treatment. An accurate diagnosis is essential for proper rehabilitation of moderate to severe injuries.
