Overview
The most common cause of Heel Pain is plantar fasciitis which is commonly referred to as a heel spur. Plantar fascia is a broad band of fibrous tissue which runs along the bottom surface of the foot, from the heel to the toes. Plantar fasciitis is a condition in which the plantar fascia is inflamed. This condition can be very painful and cause a considerable amount of suffering.
Causes
The most common cause of heel pain in adults is plantar fasciitis, which is an inflammation of the band of tissue in the sole that connects the heel to the toes and forms the natural foot arch. Plantar fasciitis may or may not be complicated by a calcaneal spur, a small bone growth that protrudes out of the heel. Plantar fasciitis may also be referred to as plantar fasciosis. In contrast to fasciitis, which essentially means inflammation, fasciosis refers to degeneration of the tissue. In fact, if left untreated, acute plantar fasciitis may develop into a chronic painful condition, which results in slow and irreversible degeneration of the fascia, hence plantar fasciosis. The location of the pain is usually exactly under the heel but may also occur in the arch of the foot. Pain typical to plantar fasciitis is that which feels worse when arising on to your feet such as in mornings or after sitting down for a while, and usually progresses in severity when left untreated.
Symptoms
Usually worse with the first few steps in the morning or at the initial point of activity. The latter usually gets better with continued activity (squeaky hinge analogy). Walking, running, sprinting, hill running and jumping will increase the pain. Often, the natural response is to walk on the outside of the foot – in supination – to lessen the stress on the plantar fascia – resulting in new problems.
Diagnosis
Your GP or podiatrist (a healthcare professional who specialises in foot care) may be able to diagnose the cause of your heel pain by asking about your symptoms and examining your heel and foot. You will usually only need further tests if you have additional symptoms that suggest the cause of your heel pain is not inflammation, such as numbness or a tingling sensation in your foot – this could be a sign of nerve damage in your feet and legs (peripheral neuropathy), your foot feels hot and you have a high temperature (fever) of 38C (100.4F) or above – these could be signs of a bone infection, you have stiffness and swelling in your heel – this could be a sign of arthritis. Possible further tests may include, blood tests, X-rays – where small doses of radiation are used to detect problems with your bones and tissues, a magnetic resonance imaging (MRI) scan or ultrasound scan, which are more detailed scans.
Non Surgical Treatment
If you develop heel pain, you can try several methods at home to ease your discomfort. For example rest as much as possible, apply ice to the heel for 10 to 15 minutes twice a day, use over-the-counter pain medications, wear shoes that fit properly, wear night splints, a special device that stretches the foot while you sleep, use heel cups or shoe inserts to reduce pain, If these home care strategies do not ease your pain, you will need to see your doctor. He or she will perform a physical exam and ask you about your symptoms and when they began. Your doctor may also take an X-ray to determine the cause of your heel pain. Once your doctor knows what is causing your pain, he or she will be able to provide you with the appropriate treatment. In many cases, your doctor may prescribe physical therapy. This can help to strengthen the muscles and tendons in your foot, which helps to prevent further injury. If your pain is severe, your doctor may provide you with anti-inflammatory medications. These medications can be injected into the foot or taken by mouth. Your doctor may also recommend that you support your foot as much as possible-either by taping the foot or by using special footwear devices. In very rare cases, your doctor may recommend surgery to correct the problem. However, heel surgery often requires a long recovery time and may not always relieve your foot pain.
Surgical Treatment
It is rare to need an operation for heel pain. It would only be offered if all simpler treatments have failed and, in particular, you are a reasonable weight for your height and the stresses on your heel cannot be improved by modifying your activities or footwear. The aim of an operation is to release part of the plantar fascia from the heel bone and reduce the tension in it. Many surgeons would also explore and free the small nerves on the inner side of your heel as these are sometimes trapped by bands of tight tissue. This sort of surgery can be done through a cut about 3cm long on the inner side of your heel. Recently there has been a lot of interest in doing the operation by keyhole surgery, but this has not yet been proven to be effective and safe. Most people who have an operation are better afterwards, but it can take months to get the benefit of the operation and the wound can take a while to heal fully. Tingling or numbness on the side of the heel may occur after operation.
Prevention
You should always wear footwear that is appropriate for your environment and day-to-day activities. Wearing high heels when you go out in the evening is unlikely to be harmful. However, wearing them all week at work may damage your feet, particularly if your job involves a lot of walking or standing. Ideally, you should wear shoes with laces and a low to moderate heel that supports and cushions your arches and heels. Avoid wearing shoes with no heels. Do not walk barefoot on hard ground, particularly while on holiday. Many cases of heel pain occur when a person protects their feet for 50 weeks of the year and then suddenly walks barefoot while on holiday. Their feet are not accustomed to the extra pressure, which causes heel pain. If you do a physical activity, such as running or another form of exercise that places additional strain on your feet, you should replace your sports shoes regularly. Most experts recommend that sports shoes should be replaced after you have done about 500 miles in them. It is also a good idea to always stretch after exercising, and to make strength and flexibility training a part of your regular exercise routine.
