To find out where this condition gets its name, we need to look at a specific area of the foot. Your foot is made up of bones, muscles, tendons, and ligaments. The plantar fascia is a relatively inflexible, strong, fibrous band on the bottom of the foot that supports the arch of your foot. Beginning at the heel bone, the plantar fascia extends the length of your foot to connect with your toes at the ball of the foot. When you walk, your weight is distributed across your feet. Any imbalances in the mechanics of your foot and distribution of weight can potentially cause pain. Diseases involving inflammation end with “itis.” This explains the name of the condition as being an inflammation of the plantar fascia, thus plantar fasciitis. Repetitive movements such as walking or running stretch the plantar fascia. Because it is not very flexible, this can cause small tears in the fascia, which leads to inflammation and pain. Other factors such as high arches, fallen arches, or a change in the walking surface contribute to the stress placed on the plantar fascia and heel.
You are at a greater risk for developing plantar fasciitis if you are overweight or obese. This is due to the increased pressure on your plantar fascia ligaments, especially if you have sudden weight gain. Women who are pregnant often experience bouts of plantar fasciitis, particularly during late pregnancy. If you are a long distance runner, you may be more likely to develop plantar fascia problems. You are also at risk if you have a very active job that involves being on your feet often, such as a factory worker or a restaurant server. Active men and women between the ages of 40 and 70 are at the highest risk for developing plantar fasciitis. It is also slightly more common in women than men. If you have foot problems, such as very high arches or very flat feet, you may develop plantar fasciitis. Tight Achilles tendons (the tendons attaching the calf muscles to the heels) may also result in plantar fascia pain. Simply wearing shoes with soft soles and poor arch support can also result in plantar fasciitis. Plantar fasciitis is not caused by heel spurs. A heel spur is a hook of bone that can form on the heel bone (calcaneus) of the foot. One out of every 10 people has a heel spur, but only one out of 20 people with heel spurs experience pain, according to OrthoInfo.
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.
To arrive at a diagnosis, the foot and ankle surgeon will obtain your medical history and examine your foot. Throughout this process the surgeon rules out all the possible causes for your heel pain other than plantar fasciitis. In addition, diagnostic imaging studies such as x-rays or other imaging modalities may be used to distinguish the different types of heel pain. Sometimes heel spurs are found in patients with plantar fasciitis, but these are rarely a source of pain. When they are present, the condition may be diagnosed as plantar fasciitis/heel spur syndrome.
Non Surgical Treatment
There are a number of treatments that can help relieve heel pain and speed up your recovery. These include resting your heel, try to avoid walking long distances and standing for long periods, regular stretching, stretching your calf muscles and plantar fascia, pain relief, using an icepack on the affected heel and taking painkillers, such as non-steroidal anti-inflammatory drugs (NSAIDs) wearing good-fitting shoes that support and cushion your foot, running shoes are particularly useful, using supportive devices such as orthoses (rigid supports that are put inside the shoe) or strapping. Around four out of five cases of heel pain resolve within a year. However, having heel pain for this length of time can often be frustrating and painful. In around one in 20 cases, the above treatments are not enough, and surgery may be recommended to release the plantar fascia.
In very rare cases plantar fascia surgery is suggested, as a last resort. In this case the surgeon makes an incision into the ligament, partially cutting the plantar fascia to release it. If a heel spur is present, the surgeon will remove it. Plantar Fasciitis surgery should always be considered the last resort when all the conventional treatment methods have failed to succeed. Endoscopic plantar fasciotomy (EPF) is a form of surgery whereby two incisions are made around the heel and the ligament is being detached from the heel bone allowing the new ligament to develop in the same place. In some cases the surgeon may decide to remove the heel spur itself, if present. Just like any type of surgery, Plantar Fascia surgery comes with certain risks and side effects. For example, the arch of the foot may drop and become weak. Wearing an arch support after surgery is therefore recommended. Heel spur surgeries may also do some damage to veins and arteries of your foot that allow blood supply in the area. This will increase the time of recovery.
