Understand Heel Pain And Discomfort

Overview



Does it feel like you have a nail in your heel? After walking for a few minutes does the pain slowly disappear? Millions of people each year are faced with this type of pain. While there may be other causes, the most common is Plantar Fasciitis. Plantar Faciitis is an inflammation of the fibrous tissue, called the plantar fasciia, that runs along the bottom of your foot that connects the heel (calcaneus) to the toes (metatarsals). Treatment for this condition can take many forms including: stretching exercises, drugs, orthotics, injections, and in rare cases surgical procedures. Until now the treatment methods have addressed the active conscious periods only to be undone when a person goes to bed or sits in the easy chair relaxing.

Causes

To understand the cause of the pain one must understand the anatomy of the foot and some basic mechanics in the function of the foot. A thick ligament, called the plantar fascia, is attached into the bottom of the heel and fans out into the ball of the foot, attaching into the base of the toes. The plantar fascia is made of dense, fibrous connective tissue that will stretch very little. It acts something like a shock absorber. As the foot impacts the ground with each step, it flattens out lengthening the foot. This action pulls on the plantar fascia, which stretches slightly. When the heel comes off the ground the tension on the ligament is released. Anything that causes the foot to flatten excessively will cause the plantar fascia to stretch greater that it is accustom to doing. One consequence of this is the development of small tears where the ligament attaches into the heel bone. When these small tears occur, a very small amount of bleeding occurs and the tension of the plantar fascia on the heel bone produces a spur on the bottom of the heel to form. Pain experienced in the bottom of the heel is not produced by the presence of the spur. The pain is due to excessive tension of the plantar fascia as it tears from its attachment into the heel bone. Heel spur formation is secondary to the excessive pull of the plantar fascia where it attaches to the heel bone. Many people have heel spurs at the attachment of the plantar fascia with out having any symptoms or pain. There are some less common causes of heel pain but they are relatively uncommon. There are several factors that cause the foot to flatten and excessively stretching the plantar fascia. The primary factor is the structure of a joint complex below the ankle joint, called the subtalar joint. The movement of this joint complex causes the arch of the foot to flatten and to heighten. Flattening of the arch of the foot is termed pronation and heightening of the arch is called supination. If there is excessive pronation of the foot during walking and standing, the plantar fascia is strained. Over time, this will cause a weakening of the ligament where it attaches into the heel bone, causing pain. When a person is at rest and off of their feet, the plantar fascia attempts to mend itself. Then, with the first few steps the fascia re-tears causing pain. Generally, after the first few steps the pain diminishes. This is why the heel pain tends to be worse the first few steps in the morning or after rest. Another factor that contributes to the flattening of the arch of the foot is tightness of the calf muscles. The calf muscle attaches into the foot by the achilles tendon into the back of the heel. When the calf muscle is tight it limits the movement of the ankle joint. When ankle joint motion is limited by the tightness of the calf muscle it forces the subtalar joint to pronate excessively. Excessive subtalar joint pronation can cause several different problems to occur in the foot. In this instance, it results in excessive tension of the plantar fascia. Tightness of the calf muscles can be a result of several different factors. Exercise, such as walking or jogging will cause the calf muscle to tighten. Inactivity or prolonged rest will also cause the calf muscle to tighten. Women who wear high heels and men who wear western style cowboy boots will, over time, develop tightness in the calf muscles.

Symptoms

The most common complaint is pain and stiffness in the bottom of the heel. Heel pain may be sharp or dull, and it may develop slowly over time or suddenly after intense activity. The pain is typically worse in the morning, when taking your first steps of the day. After standing or sitting for a while. When climbing stairs.

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

Treatment for plantar fasciitis should be directed at resting the plantar fascia, providing support for the arch area and limiting pronation. This is often accomplished with the use of supportive strapping with athletic tape, arch supports and orthotics. Heel lifts may also be helpful. Anti-inflammatories, pills as well as cortisone injections, may be effective as an adjunctive treatment by speeding up the reduction of inflammation. However, if used alone, anti-inflammatories rarely lead to resolution of the condition. Stretching exercises, physical therapy and night splints may also be helpful. The majority of cases respond to non-surgical treatment although it may take several weeks to reach a comfortable level. In those cases that do not respond adequately to conservative measures, surgical release of the plantar fascia may be considered. However, a new non-surgical treatment called Extracorporeal Shockwave Therapy (ESWT) is now available as an option for recalcitrant plantar fasciitis. ESWT was approved by the FDA recently for the treatment of chronic heel pain. It has been in use for several years on thousands of patients in Europe and has been successfully used to restore patients with chronic plantar fasciitis to a normal, active lifestyle. ESWT is a non-invasive procedure that uses high intensity sound waves similar to what is routinely used to treat kidney stones. The treatment is usually performed in the office or in an outpatient surgical center. The procedure is performed under local anesthesia and takes about 25 minutes. The shockwaves are directed at the plantar fascia and stimulate an inflammatory healing response.

Surgical Treatment

At most 95% of heel pain can be treated without surgery. A very low percentage of people really need to have surgery on the heel. It is a biomechanical problem and it?s very imperative that you not only get evaluated, but receive care immediately. Having heel pain is like having a problem with your eyes; as you would get glasses to correct your eyes, you should look into orthotics to correct your foot. Orthotics are sort of like glasses for the feet. They correct and realign the foot to put them into neutral or normal position to really prevent heel pain, and many other foot issues. Whether it be bunions, hammertoes, neuromas, or even ankle instability, a custom orthotic is something worth considering.

Prevention



The following steps will help prevent plantar fasciitis or help keep the condition from getting worse if you already have it. The primary treatment is rest. Cold packs application to the area for 20 minutes several times a day or after activities give some relief. Over-the-counter pain medications can help manage the pain, consult your healthcare professional. Shoes should be well cushioned, especially in the midsole area, and should have the appropriate arch support. Some will benefit from an orthotic shoe insert, such as a rubber heel pad for cushioning. Orthotics should be used in both shoes, even if only one foot hurts. Going barefoot or wearing slipper puts stress on your feet. Put on supportive shoes as soon as you get out of bed. Calf stretches and stretches using a towel (place the towel under the ball of your feet and pull gently the towel toward you and hold a few seconds) several times a day, especially when first getting up in the morning. Stretching the Achilles tendon at the back of the heel is especially important before sports, but it is helpful for nonathletes as well. Increasing your exercise levels gradually. Staying at a healthy weight. Surgery is very rarely required.
