What Brings About Plantar Fasciitis

Foot Pain

Overview

Plantar fasciitis is a poorly understood condition. There is little consensus among medical professionals about what causes the problem, and no treatments have been reliably proven to treat it. A number of theories exists for why plantar fasciitis develops, but the ineffectiveness of conventional treatments suggests something is missing. The plantar fascia is a band of connective tissue that runs along the underside of the foot from the heel to the toes. The fascia helps maintain the integrity of the arch, provides shock absorption, and plays an important role in the normal mechanical function of the foot.




Causes

Repeated small injuries to the fascia (with or without inflammation) are thought to be the cause of plantar fasciitis. The injury is usually near to where the plantar fascia attaches to your heel bone. You are more likely to injure your plantar fascia in certain situations. For example, if you are on your feet for a lot of the time, or if you do lots of walking, running, standing, etc, when you are not used to it. (Plantar fasciitis may be confused with 'Policeman's heel', but they are different. Policeman's heel is plantar calcaneal bursitis - inflammation of the sack of fluid (bursa) under the heel bone. This is not as common as plantar fasciitis.) Also, people with a sedentary lifestyle are more prone to plantar fasciitis. If you have recently started exercising on a different surface, for example, running on the road instead of a track. If you have been wearing shoes with poor cushioning or poor arch support. If you are overweight this will put extra strain on your heel. If there is overuse or sudden stretching of your sole. For example, athletes who increase running intensity or distance; poor technique starting 'off the blocks', etc. If you have a tight Achilles tendon (the big tendon at the bottom of your calf muscles above your heel). This can affect your ability to flex your ankle and make you more likely to damage your plantar fascia. Often there is no apparent cause for plantar fasciitis, particularly in older people. A common wrong belief is that the pain is due to a bony growth or 'spur' coming from the heel bone (calcaneum). Many people have a bony spur of the heel bone but not everyone with this gets plantar fasciitis.




Symptoms

Symptoms of plantar fasciitis can occur suddenly or gradually. When they occur suddenly, there is usually intense heel pain on taking the first morning steps, known as first-step pain. This heel pain will often subside as you begin to walk around, but it may return in the late afternoon or evening. When symptoms occur gradually, a more long-lasting form of heel pain will cause you to shorten your stride while running or walking. You also may shift your weight toward the front of the foot, away from the heel.




Diagnosis

Your doctor will perform a physical exam to check for tenderness in your foot and the exact location of the pain to make sure that it’s not caused by a different foot problem. The doctor may ask you to flex your foot while he or she pushes on the plantar fascia to see if the pain gets worse as you flex and better as you point your toe. Mild redness or swelling will also be noted. Your doctor will evaluate the strength of your muscles and the health of your nerves by checking your reflexes, your muscle tone, your sense of touch and sight, your coordination, and your balance. X-rays or a magnetic resonance imaging (MRI) scan may be ordered to check that nothing else is causing your heel pain, such as a bone fracture.




Non Surgical Treatment

About 90% of plantar fasciitis cases are self-limited and will improve within six months with conservative treatment and within a year regardless of treatment. Many treatments have been proposed for the treatment of plantar fasciitis. First-line conservative approaches include rest, heat, ice, calf-strengthening exercises, techniques to stretch the calf muscles, achilles tendon, and plantar fascia, weight reduction in the overweight or obese, and nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin or ibuprofen. NSAIDs are commonly used to treat plantar fasciitis, but fail to resolve the pain in 20% of people. Extracorporeal shockwave therapy (ESWT) is an effective treatment modality for plantar fasciitis pain unresponsive to conservative nonsurgical measures for at least three months. Corticosteroid injections are sometimes used for cases of plantar fasciitis refractory to more conservative measures. The injections may be an effective modality for short-term pain relief up to one month, but studies failed to show effective pain relief after three months. Notable risks of corticosteroid injections for plantar fasciitis include plantar fascia rupture, skin infection, nerve or muscle injury, or atrophy of the plantar fat pad. Custom orthotic devices have been demonstrated as an effective method to reduce plantar fasciitis pain for up to 12 weeks. Night splints for 1-3 months are used to relieve plantar fasciitis pain that has persisted for six months. The night splints are designed to position and maintain the ankle in a neutral position thereby passively stretching the calf and plantar fascia overnight during sleep. Other treatment approaches may include supportive footwear, arch taping, and physical therapy.

Surgical Treatment

Surgery is rarely needed in the treatment of plantar fasciitis. The vast majority of patients diagnosed with plantar fasciitis will recover given ample time. With some basic treatment steps, well over 90% of patients will achieve full recovery from symptoms of plantar fasciitis within one year of the onset of treatment. Simple treatments include anti-inflammatory medication, shoe inserts, and stretching exercises. In patients where a good effort with these treatments fails to provide adequate relief, some more aggressive treatments may be attempted. These include cortisone injections or extracorporeal shock wave treatments.




Prevention

It is not always possible to prevent heel pain, but there are measures you can take to help avoid further episodes. Healthy weight. Being overweight can place excess pressure and strain on your feet, particularly on your heels. This increases the risk of damaging your feet and heels. If you are overweight, losing weight and maintaining a healthy weight by combining regular exercise with a healthy, balanced diet can be beneficial for your feet. You can calculate your body mass index (BMI) to find out whether you are a healthy weight for your height and build. To work out your BMI, divide your weight in kilograms by your height in metres squared. A BMI of less than 18.5 means that you are underweight, 18.5-24.9 means that your weight is healthy, 25-29 means that you are overweight, 30-40 means that you are obese, over 40 means that you are morbidly obese. You can also use the BMI healthy weight calculator to work out your BMI. Healthy feet. 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.
