Every time you take a step, one of your heels has to support the whole weight of your body. As you move, the load is equal to 20 times your own body weight. The load is softened by a pillow of fat under the heel and a large sinew or ligament (the fibrous tissue that joins muscle and bone together) under the sole of the foot. This sinew is called the plantar fascia and it pulls the heel bone forward (in opposition to the Achilles tendon, which pulls it backwards). If an athlete does not warm up properly or a person with a sedentary job exercises heavily during the weekends, they might overload the muscles of the calf or strain the Achilles tendon, which joins these muscles to the heel bone. When overloaded the tendon becomes tight and painfully inflamed, which places extra strain on the plantar fascia and muscles in the soles of the foot. The strained plantar fascia becomes inflamed and may even develop tiny cracks. This is known as plantar fasciitis. Every time you sit down, sleep or otherwise rest your legs, the muscles of the sole of the foot will contract in an attempt to protect the damaged sinew. The pain in the heel will then no longer be felt. But when you get up again and put weight on the foot, the foot and ankle may feel stiff (because of the inflammation) and the pain will return either at the back of the heel or on the soles of the feet. When you start to move, the plantar fascia may crack even more causing a vicious cycle of damage and pain. Inflammation at the point where the Achilles tendon (at the back of the heel) or the plantar fascia (under the heel) join the heel bone (a bone known as the Calcaneum) stimulates cells that form bone to deposit bone in this area, eventually leading to the build up of a bony prominence on the heel bone called a calcaneal spur. But it's not the spur itself that causes the pain. The spur is a sign of chronic inflammation in the connective tissues, which is the result of a prolonged overload. It should also be pointed out that heel spurs can occur on their own, without plantar fasciitis or pain, or may be linked to some types of arthritis (inflammation of the joints). And plantar fasciitis or Achilles tendonitis don't necessarily lead to spur formation.
The plantar fascia spans the long arch of the foot from the heel to the base of the toes, where it blends with the soft tissues, then anchoring to the base of the toes. Plantar Fascia. The plantar fascia is a common cause of heel pain. As the bony attachment at the heel is considered the plantar fascia?s ?weak spot?, the patient will present with pain at the heel, mainly on the inside. The most common predisposing factor to this condition is the pronating (flattening feet) - 52% - whilst there is also some evidence that a very high arch, in a rigid foot (pes cavus), also was reasonably common - 42%.
Plantar fascia usually causes pain and stiffness on the bottom of your heel although some people have heel spurs and suffer no symptoms at all. Occasionally, heel pain is also associated with other medical disorders such as arthritis (inflammation of the joint), bursitis (inflammation of the tissues around the joint). Those who have symptoms may experience ?First step? pain (stone bruise sensation) after getting out of bed or sitting for a period of time. Pain after driving. Pain on the bottom of your heel. Deep aching pain. Pain can be worse when barefoot.
The diagnosis of heel pain and heel spurs is made by a through history of the course of the condition and by physical exam. Weight bearing x-rays are useful in determining if a heel spur is present and to rule out rare causes of heel pain such as a stress fracture of the heel bone, the presence of bone tumors or evidence of soft tissue damage caused by certain connective tissue disorders.
Non Surgical Treatment
Heel pain often goes away on its own with home care. For heel pain that isn't severe, try the following. Rest. If possible, avoid activities that put stress on your heels, such as running, standing for long periods or walking on hard surfaces. Ice. Place an ice pack or bag of frozen peas on your heel for 15 to 20 minutes three times a day. New shoes. Be sure your shoes fit properly and provide plenty of support. If you're an athlete, choose shoes appropriate for your sport and replace them regularly. Foot supports. Heel cups or wedges that you buy in the drugstore often provide relief. Custom-made orthotics usually aren't needed for heel problems. Over-the-counter pain medications. Aspirin or ibuprofen (Advil, Motrin IB, others) can reduce inflammation and pain.
Only a relatively few cases of heel pain require surgery. If required, surgery is usually for the removal of a spur, but also may involve release of the plantar fascia, removal of a bursa, or a removal of a neuroma or other soft-tissue growth.
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. Do not walk barefoot on hard ground, particularly while on holiday. Many cases of heel pain occur when a person protects their feet for 50 weeks of the year and then suddenly walks barefoot while on holiday. Their feet are not accustomed to the extra pressure, which causes heel pain. If you do a physical activity, such as running or another form of exercise that places additional strain on your feet, you should replace your sports shoes regularly. Most experts recommend that sports shoes should be replaced after you have done about 500 miles in them. It is also a good idea to always stretch after exercising, and to make strength and flexibility training a part of your regular exercise routine.
