The plantar fascia is a tough and flexible band of tissue that runs under the sole of the foot. It connects the heel bone with the bones of the foot, and acts as a kind of shock absorber to the foot. Sudden damage, or damage that occurs over many months or years, can cause tiny tears (microtears) to develop inside the tissue of the plantar fascia. This can cause the plantar fascia to thicken, resulting in heel pain. The surrounding tissue and the heel bone can also sometimes become inflamed.
As a person gets older, the plantar fascia becomes less like a rubber band and more like a rope that doesn’t stretch very well. The fat pad on the heel becomes thinner and can’t absorb as much of the shock caused by walking. The extra shock damages the plantar fascia and may cause it to swell, tear or bruise. You may notice a bruise or swelling on your heel. Other risk factors for plantar fasciitis include being overweight and obesity. Diabetes. Spending most of the day on your feet. Becoming very active in a short period of time. Being flat-footed or having a high arch.
Plantar fasciitis and heel spur pain usually begins in the bottom of the heel, and frequently radiates into the arch. At times, however, the pain may be felt only in the arch. The pain is most intense when first standing, after any period of rest. Most people with this problem experience their greatest pain in the morning, with the first few steps after sleeping. After several minutes of walking, the pain usually becomes less intense and may disappear completely, only to return later with prolonged walking or standing. If a nerve is irritated due to the swollen plantar fascia, this pain may radiate into the ankle. In the early stages of Plantar Fasciitis and Heel Spurs, the pain will usually subside quickly with getting off of the foot and resting. As the disease progresses, it may take longer periods of time for the pain to subside.
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
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.
If treatment hasn’t worked and you still have painful symptoms after a year, your GP may refer you to either an orthopaedic surgeon, a surgeon who specialises in surgery that involves bones, muscles and joints, a podiatric surgeon, a podiatrist who specialises in foot surgery. Surgery is sometimes recommended for professional athletes and other sportspeople whose heel pain is adversely affecting their career. Plantar release surgery. Plantar release surgery is the most widely used type of surgery for heel pain. The surgeon will cut the fascia to release it from your heel bone and reduce the tension in your plantar fascia. This should reduce any inflammation and relieve your painful symptoms. Surgery can be performed either as, open surgery, where the section of the plantar fascia is released by making a cut into your heel, endoscopic or minimal incision surgery – where a smaller incision is made and special instruments are inserted through the incision to gain access to the plantar fascia. Endoscopic or minimal incision surgery has a quicker recovery time, so you will be able to walk normally much sooner (almost immediately), compared with two to three weeks for open surgery. A disadvantage of endoscopic surgery is that it requires both a specially trained surgical team and specialised equipment, so you may have to wait longer for treatment than if you were to choose open surgery. Endoscopic surgery also carries a higher risk of damaging nearby nerves, which could result in symptoms such as numbness, tingling or some loss of movement in your foot. As with all surgery, plantar release carries the risk of causing complications such as infection, nerve damage and a worsening of your symptoms after surgery (although this is rare). You should discuss the advantages and disadvantages of both techniques with your surgical team. Extracorporeal shockwave therapy (EST) is a fairly new type of non-invasive treatment. Non-invasive means it does not involve making cuts into your body. EST involves using a device to deliver high-energy soundwaves into your heel. The soundwaves can sometimes cause pain, so a local anaesthetic may be used to numb your heel. It is claimed that EST works in two ways. It is thought to, have a “numbing” effect on the nerves that transmit pain signals to your brain, help stimulate and speed up the healing process. However, these claims have not yet been definitively proven. The National Institute for Health and Care Excellence (NICE) has issued guidance about the use of EST for treating plantar fasciitis. NICE states there are no concerns over the safety of EST, but there are uncertainties about how effective the procedure is for treating heel pain. Some studies have reported that EST is more effective than surgery and other non-surgical treatments, while other studies found the procedure to be no better than a placebo (sham treatment).
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.
