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 most common local causes of heel pain include. Plantar fasciitis, plantar fasciitis is a painful inflammation of the plantar fascia, a fibrous band of tissue on the sole of the foot that helps to support the arch. Plantar fasciitis occurs when the plantar fascia is overloaded or overstretched. This causes small tears in the fibers of the fascia, especially where the fascia meets the heel bone. Plantar fasciitis may develop in just about anyone but it is particularly common in the following groups of people: people with diabetes, obese people, pregnant women, runners, volleyball players, tennis players and people who participate in step aerobics or stair climbing. You also can trigger plantar fasciitis by pushing a large appliance or piece of furniture or by wearing worn out or poorly constructed shoes. In athletes, plantar fasciitis may follow a period of intense training, especially in runners who push themselves to run longer distances. People with flat feet have a higher risk of developing plantar fasciitis. Heel spur, a heel spur is an abnormal growth of bone at the area where the plantar fascia attaches to the heel bone. It is caused by long-term strain on the plantar fascia and muscles of the foot, especially in obese people, runners or joggers. As in plantar fasciitis, shoes that are worn out, poorly fitting or poorly constructed can aggravate the problem. Heel spurs may not be the cause of heel pain even when seen on an X-ray. In fact, they may develop as a reaction to plantar fasciitis. Calcaneal apophysitis, in this condition, the center of the heel bone becomes irritated as a result of a new shoe or increased athletic activity. This pain occurs in the back of the heel, not the bottom. Calcaneal apophysitis is a fairly common cause of heel pain in active, growing children between the ages of 8 and 14. Although almost any boy or girl can be affected, children who participate in sports that require a lot of jumping have the highest risk of developing this condition. Bursitis means inflammation of a bursa, a sac that lines many joints and allows tendons and muscles to move easily when the joint is moving. In the heel, bursitis may cause pain at the underside or back of the heel. In some cases, heel bursitis is related to structural problems of the foot that cause an abnormal gait (way of walking). In other cases, wearing shoes with poorly cushioned heels can trigger bursitis. Pump bump, this condition, medically known as posterior calcaneal exostosis, is an abnormal bony growth at the back of the heel. It is especially common in young women, in whom it is often related to long-term bursitis caused by pressure from pump shoes. Like other parts of the foot, the heel can be bumped and bruised accidentally. Typically, this happens as a "stone bruise," an impact injury caused by stepping on a sharp object while walking barefoot. In most cases, Achilles tendonitis (inflammation of the Achilles tendon) is triggered by overuse, especially by excessive jumping during sports. However, it also can be related to poorly fitting shoes if the upper back portion of a shoe digs into the Achilles tendon at the back of the heel. Less often, it is caused by an inflammatory illness, such as ankylosing spondylitis (also called axial spondylarthritis), reactive arthritis, gout or rheumatoid arthritis. Compression of a small nerve (a branch of the lateral plantar nerve) can cause pain, numbness or tingling in the heel area. In many cases, this nerve compression is related to a sprain, fracture or varicose (swollen) vein near the heel.
Both heel pain and heel spurs are frequently associated with an inflammation of the long band of tissue that connects the heel and the ball of the foot. The inflammation of this arch area is called plantar fasciitis. The inflammation maybe aggravated by shoes that lack appropriate support and by the chronic irritation that sometimes accompanies an athletic lifestyle. Achilles Tendinopathy, Pain and inflammation of the tendon at the back of the heel that connects the calf muscle to the foot. Sever?s, Often found in children between the ages of 8 - 13 years and is an inflammation of the calcaneal epiphyseal plate (growth plate) in the back of the heel. Bursitis, An inflamed bursa is a small irritated sack of fluid at the back of the heel. Other types of heel pain include soft tissue growths, Haglunds deformity (bone enlargement at the back of the heel), bruises or stress fractures and possible nerve entrapment.
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
If you have experienced painful heels try wearing your shoes around your house in the evening. Don't wear slippers or socks or go barefoot. You may also try gentle calf stretches for 20 to 30 seconds on each leg. This is best done barefoot, leaning forward towards a wall with one foot forward and one foot back. If the pain persists longer than one month, you should visit a podiatrist for evaluation and treatment. Your feet should not hurt, and professional podiatric care may be required to help relieve your discomfort. If you have not exercised in a long time, consult your podiatric physician before starting a new exercise program. Begin an exercise program slowly. Don't go too far or too fast. Purchase and maintain good shoes and replace them regularly. Stretch each foot and achilles tendon before and after exercise. Avoid uneven walking surfaces or stepping on rocks as much as possible. Avoid going barefoot on hard surfaces. Vary the incline on a treadmill during exercise. Nobody walks uphill all the time. If it hurts, stop. Don't try to "work through the pain." Your podiatric physician/surgeon has been trained specifically and extensively in the diagnosis and treatment of all manner of foot conditions. This training encompasses all of the intricately related systems and structures of the foot and lower leg including neurological, circulatory, skin, and the musculoskeletal system, which includes bones, joints, ligaments, tendons, muscles, and nerves.
When a diagnosis of plantar fasciitis is made early, most patients respond to conservative treatment and don?t require surgical intervention. Often, when there is a secondary diagnosis contributing to your pain, such as an entrapped nerve, and you are non-responsive to conservative care, surgery may be considered. Dr. Talarico will discuss all options and which approach would be the most beneficial for your condition.
heel cushions for plantar fasciitis
It may not be possible to prevent all cases of heel pain. However, there are some easy steps that you can take to avoid injury to the heel and prevent pain. Whenever possible, you should wear shoes that fit properly and support the foot, wear the right shoes for physical activity, stretch your muscles before exercising, pace yourself during physical activity, maintain a healthy diet, rest when you feel tired or when your muscles ache, maintain a healthy weight.
