Plantar fasciitis is a painful condition causing heel pain and many people with the condition also have heel spurs. It affects the band of tissue (plantar fascia) that supports the middle part of the foot and runs along the sole of the foot from the heel to the ball of the foot. Usually the plantar fascia is strong and flexible but due to certain factors it can become irritated and inflamed where the plantar fascia joins the bone in the foot. Heel spurs occur when there’s constant pulling of the fascia at the heel bone. This leads to a bony growth or spur. The symptoms of plantar fasciitis are pain in the arch of the foot or heel. This pain is usually worse in the morning after rest when the plantar fascia tightens and shortens. Heel spurs cause a stabbing pain at the bottom or front of the heel bone.
The most common cause of plantar fasciitis relates to faulty structure of the foot. For example, people who have problems with their arches, either overly flat feet or high-arched feet, are more prone to developing plantar fasciitis. Wearing non-supportive footwear on hard, flat surfaces puts abnormal strain on the plantar fascia and can also lead to plantar fasciitis. This is particularly evident when one’s job requires long hours on the feet. Obesity may also contribute to plantar fasciitis.
Pain is the main symptom. This can be anywhere on the underside of your heel. However, commonly, one spot is found as the main source of pain. This is often about 4 cm forward from your heel, and may be tender to touch. The pain is often worst when you take your first steps on getting up in the morning, or after long periods of rest where no weight is placed on your foot. Gentle exercise may ease things a little as the day goes by, but a long walk or being on your feet for a long time often makes the pain worse. Resting your foot usually eases the pain. Sudden stretching of the sole of your foot may make the pain worse, for example, walking up stairs or on tiptoes. You may limp because of pain. Some people have plantar fasciitis in both feet at the same time.
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
No single treatment works best for everyone with plantar fasciitis. But there are many things you can try to help your foot get better. Give your feet a rest. Cut back on activities that make your foot hurt. Try not to walk or run on hard surfaces. To reduce pain and swelling, try putting ice on your heel. Or take an over-the-counter pain reliever like ibuprofen (such as Advil or Motrin) or naproxen (such as Aleve). Do toe stretches camera.gif, calf stretches camera.gif and towel stretches camera.gif several times a day, especially when you first get up in the morning. (For towel stretches, you pull on both ends of a rolled towel that you place under the ball of your foot.) Get a new pair of shoes. Pick shoes with good arch support and a cushioned sole. Or try heel cups or shoe inserts. Use them in both shoes, even if only one foot hurts. If these treatments do not help, your doctor may recommend splints that you wear at night, shots of medicine (such as a steroid) in your heel, or other treatments. You probably will not need surgery. Doctors only suggest it for people who still have pain after trying other treatments for 6 to 12 months. Plantar fasciitis most often occurs because of injuries that have happened over time. With treatment, you will have less pain within a few weeks. But it may take time for the pain to go away completely. It may take a few months to a year. Stay with your treatment. If you don’t, you may have constant pain when you stand or walk. The sooner you start treatment, the sooner your feet will stop hurting.
Plantar fasciotomy is often considered after conservative treatment has failed to resolve the issue after six months and is viewed as a last resort. Minimally invasive and endoscopic approaches to plantar fasciotomy exist but require a specialist who is familiar with certain equipment. Heel spur removal during plantar fasciotomy has not been found to improve the surgical outcome. Plantar heel pain may occur for multiple reasons and release of the lateral plantar nerve branch may be performed alongside the plantar fasciotomy in select cases. Possible complications of plantar fasciotomy include nerve injury, instability of the medial longitudinal arch of the foot, fracture of the calcaneus, prolonged recovery time, infection, rupture of the plantar fascia, and failure to improve the pain. Coblation (TOPAZ) surgery has recently been proposed as alternative surgical approaches for the treatment of recalcitrant plantar fasciitis.
The following exercises are commonly prescribed to patients with this condition. You should discuss the suitability of these exercises with your physiotherapist prior to beginning them. Generally, they should be performed 2 – 3 times daily and only provided they do not cause or increase symptoms. Your physiotherapist can advise when it is appropriate to begin the initial exercises and eventually progress to the intermediate and advanced exercises. As a general rule, addition of exercises or progression to more advanced exercises should take place provided there is no increase in symptoms. Calf Stretch with Towel. Begin this stretch in long sitting with your leg to be stretched in front of you. Your knee and back should be straight and a towel or rigid band placed around your foot as demonstrated. Using your foot, ankle and the towel, bring your toes towards your head until you feel a stretch in the back of your calf, Achilles tendon, plantar fascia or leg. Hold for 5 seconds and repeat 10 times at a mild to moderate stretch provided the exercise is pain free. Resistance Band Calf Strengthening. Begin this exercise with a resistance band around your foot as demonstrated and your foot and ankle held up towards your head. Slowly move your foot and ankle down against the resistance band as far as possible and comfortable without pain, tightening your calf muscle. Very slowly return back to the starting position. Repeat 10 – 20 times provided the exercise is pain free.
