The plantar fascia acts like a bowstring and supports the arch and several muscles inside the foot. When there is increased stress on the arch, microscopic tears can occur within the plantar fascia, usually at its attachment on the heel. This results in inflammation and pain with standing and walking and sometimes at rest.
Plantar fasciitis is a painful disorder in the lower part of your foot usually around the heel. That pain usually hurts as you get up in the morning when you try to stand on your feet, or after any periods of inactivity. It is a disorder of a tough and strong band that connects the heel bone to the toes. Plantar Fasciitis is caused by injuring that tough band on the bottom of the foot. The following may be the causes of plantar fasciitis. Tight calf muscles or tight Achilles tendon produces repetitive over-stretching of the plantar fascia. Gait and balance Problem may be a dominant cause of this disorder. Many people have a special style of walking, with something unique that causes some kind of imbalance in their body. It might be something like locked knees, feet that turn-out, a weak abdomen etc. This imbalance may place some pressure on the fascia, which eventually causes plantar fasciitis. Weak foot muscles don’t give enough support to the plantar fascia. The small muscles in the foot give the foot its shape by keeping the bones in place and by expanding and contracting to make a movement. Weak foot muscles will allow greater stress on the fascia. Foot anatomical problems such as flat feet or high arches can make the fascia ligament work or stretch abnormally. Flattening of the fat pad at the sole of the feet under the heels is a Degeneration process that is caused by poor footwear or by age. Shoes that have no proper heel cup can flatten that fat pad quite quickly and cause this disorder. Walking in shoes which do not have good arch support is considered to be a cause of plantar fasciitis. Wearing inadequate or worn out shoes may place more stress on the fascia ligament. If you wear shoes that don't fit you by size or width, you may put your feet under excessive stress. Overweight Men and women are more vulnerable to developing the condition because of the excess weight on the foot. Pregnant women are at risk due to gaining weight through pregnancy and due to the pregnancy hormones that make ligaments loosen and relax. Sudden increase of activity like starting to run long distance or complete change of daily activity can cause heel pain and this disorder. Practice of repetitive athletic activities, like long distance running, playing a ball game, dancing or jumping, is a common cause for the disorder. Actually it is considered as one of the most common running injuries. Spending long periods of time on your feet everyday can cause plantar fasciitis. Working on your feet a few hours a day evey day may be the reason for your heel pain.
Most people with plantar fasciitis have pain when they take their first steps after they get out of bed or sit for a long time. You may have less stiffness and pain after you take a few steps. But your foot may hurt more as the day goes on. It may hurt the most when you climb stairs or after you stand for a long time. If you have foot pain at night, you may have a different problem, such as arthritis , or a nerve problem such as tarsal tunnel syndrome.
Plantar fasciitis is usually diagnosed by a health care provider after consideration of a person’s presenting history, risk factors, and clinical examination. Tenderness to palpation along the inner aspect of the heel bone on the sole of the foot may be elicited during the physical examination. The foot may have limited dorsiflexion due to tightness of the calf muscles or the Achilles tendon. Dorsiflexion of the foot may elicit the pain due to stretching of the plantar fascia with this motion. Diagnostic imaging studies are not usually needed to diagnose plantar fasciitis. However, in certain cases a physician may decide imaging studies (such as X-rays, diagnostic ultrasound or MRI) are warranted to rule out other serious causes of foot pain. Bilateral heel pain or heel pain in the context of a systemic illness may indicate a need for a more in-depth diagnostic investigation. Lateral view x-rays of the ankle are the recommended first-line imaging modality to assess for other causes of heel pain such as stress fractures or bone spur development. Plantar fascia aponeurosis thickening at the heel greater than 5 millimeters as demonstrated by ultrasound is consistent with a diagnosis of plantar fasciitis. An incidental finding associated with this condition is a heel spur, a small bony calcification on the calcaneus (heel bone), which can be found in up to 50% of those with plantar fasciitis. In such cases, it is the underlying plantar fasciitis that produces the heel pain, and not the spur itself. The condition is responsible for the creation of the spur though the clinical significance of heel spurs in plantar fasciitis remains unclear.
Non Surgical Treatment
Treatment for heel pain usually involves using a combination of techniques, such as stretches and painkillers, to relieve pain and speed up recovery. Most cases of heel pain get better within 12 months. Surgery may be recommended as a last resort if your symptoms don't improve after this time. Only 1 in 20 people with heel pain will need surgery. Whenever possible, rest the affected foot by not walking long distances and standing for long periods. However, you should regularly stretch your feet and calves using exercises such as those described below. Pain relief. Non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, can be used to help relieve pain. Some people also find applying an ice pack to the affected heel for 5-10 minutes can help relieve pain and inflammation. However, do not apply an ice pack directly to your skin. Instead, wrap it in a towel. If you do not have an ice pack, you can use a packet of frozen vegetables.
Surgery may be considered in very difficult cases. Surgery is usually only advised if your pain has not eased after 12 months despite other treatments. The operation involves separating your plantar fascia from where it connects to the bone; this is called a plantar fascia release. It may also involve removal of a spur on the calcaneum if one is present. Surgery is not always successful. It can cause complications in some people so it should be considered as a last resort. Complications may include infection, increased pain, injury to nearby nerves, or rupture of the plantar fascia.
Stretching your plantar fasciitis is something you can do at home to relieve pain and speed healing. Ice massage performed three to four times per day in 15 to 20 minute intervals is also something you can do to reduce inflammation and pain. Placing arch supports in your shoes absorbs shock and takes pressure off the plantar fascia.
