Plantar fasciitis is a painful condition affecting the bottom of the foot. It is a common cause of heel pain and is sometimes called a heel spur. Plantar fasciitis is the correct term to use when there is active inflammation. Plantar fasciosis is more accurate when there is no inflammation but chronic degeneration instead. Acute plantar fasciitis is defined as inflammation of the origin of the plantar fascia and fascial structures around the area. Plantar fasciitis or fasciosis is usually just on one side. In about 30 per cent of all cases, both feet are affected. This guide will help you understand how plantar fasciitis develops, how the condition causes problems, what can be done for your pain.
Near the inflamed plantar fascia attachment, but not in it, some extra bone may form, producing a small "spur". In fact, it is a shelf of bone, not a sharp spur. These "heel spurs" are commoner in people with plantar fascitis, but they can be found in people with no heel pain. The heel spur is caused by the same process as the heel pain, but the spur is not itself the cause of the pain.
Symptoms of plantar fasciitis vary, but the classic symptom is pain after rest--when you first get out of bed in the morning, or when you get up after sitting down for a while during the day. The pain usually diminishes after a few minutes of walking, sometimes even disappearing, but the pain is commonly felt again the longer you're on the foot. Fasciitis can be aggravated by shoes that lack appropriate support, especially in the arch area, and by the chronic irritation of long-periods of standing, especially on concrete, by being overweight. It doesn't help that fascia doesn't heal particularly quickly because it has relatively poor circulation (which is why it's white in colour).
A biomechanical exam by your podiatrist will help reveal these abnormalities and in turn resolve the cause of plantar fasciitis. By addressing this cause, the patient can be offered a podiatric long-term solution to his problem.
Non Surgical Treatment
As heel pain is basically a stress problem in the tissues of the heel, the main treatment is to reduce stress. Your doctor will advise you about weight loss and appropriate footwear. A soft heel pad is useful to wear in your shoe to act as a shock-absorber when you walk. If you have a stiff ankle or tight Achilles tendon a physiotherapist can advise on exercises for these. Stretching the Achilles tendon and plantar fascia is very effective general treatment for many patients. If you have a high-arched or flat foot, a podiatrist may advise an insole to reduce stress. Simple pain-killers such as paracetamol or anti-inflammatory medicines can help reduce the pain. Ask advice from your doctor or pharmacist before taking anti-inflammatory medicines as they can have troublesome side-effects in some people. The simple measures above will help the majority of people with heel pain. If the pain continues, a splint to wear on your ankle at night to prevent your Achilles tendon tightening up while you are asleep is often very effective in improving the severe pain that many people get first thing in the morning and breaking the cycle of pain. Your GP or an orthopaedic foot and ankle surgeon or rheumatologist may inject some steroid into the attachment of the plantar fascia to damp down the inflammation. These measures will reduce the pain in most people who are not helped by simple treatment. If you still have pain after one or two injections, your doctor may want to investigate your problem a bit further. If no other medical problem or cause of stress in your heel is found, a number of other treatments can be tried. Further physiotherapy, wearing a plaster cast to rest the inflamed tissues, pain control treatments such as transcutaneous nerve stimulation (TENS) or acupuncture. Only if all non-surgical treatments fail would an operation be considered.
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.
Why do the heels of my feet hurt?
Heel pain is commonly caused from shoes that do not fit properly. In addition, shoes need to have ample cushioning and support, particularly through the heel, ball of the foot, and arch. Shoes should also be replaced if they become too worn. One sure sign of wear and tear is overly worn areas of a shoe's insoles. If the heel or ball of the foot is particularly worn, damage could easily occur since the bottom of the foot is not getting the cushioning it needs.
