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 Heel 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.
If you have pain behind your heel, you may have inflamed the area where the Achilles tendon inserts into the heel bone (retrocalcaneal bursitis). People often get this by running too much or wearing shoes that rub or cut into the back of the heel. Pain behind the heel may build slowly over time, causing the skin to thicken, become red and swell. You might develop a bump on the back of your heel that feels tender and warm to the touch. The pain might flare up when you first start an activity after resting. It often hurts too much to wear normal shoes. You may need an X-ray to see if you also have a bone spur.
Common symptoms, heel Spurs: the pain is usually worst on standing, particularly first thing in the morning when you get up. It is relatively common, though usually occurring in the over forty’s age group. There are no visible features on the heel but a deep localised painful spot can be found in or around the middle of the sole of the heel. Although it is often associated with a spur of bone sticking out of the heel bone (heel spur syndrome), approximately ten per cent of the population have heel spurs without any pain. Heel Bursitis, pain can be felt at the back of the heel when the ankle joint is moved and there may be a swelling on both sides of the Achilles tendon. Or you may feel pain deep inside the heel when it makes contact with the ground. Heel Bumps, recognised as firm bumps on the back of the heel , they are often rubbed by shoes causing pain.
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
Depending on the underlying cause, treatment can include. Rest from activities that stress the heel (such as running and jumping). Ice packs. Regular foot massage, concentrating on the arch of the foot. Professional strapping. A splint worn at night. Flexibility exercises. Ultrasound therapy. Anti-inflammatory medicine (topical or oral). Checking your posture and walking style, to correct imbalances and gait abnormalities that may contribute to the pain. Shoe inserts (orthoses) to help support the foot. In some cases, surgery may be recommended to treat conditions including neuroma, bursitis and heel spurs.
Extracorporeal shockwave therapy (EST) is a fairly new type of non-invasive treatment. Non-invasive means it does not involve making cuts into your body. EST involves using a device to deliver high-energy soundwaves into your heel. The soundwaves can sometimes cause pain, so a local anaesthetic may be used to numb your heel. It is claimed that EST works in two ways. It is thought to have a “numbing” effect on the nerves that transmit pain signals to your brain, help stimulate and speed up the healing process. However, these claims have not yet been definitively proven. The National Institute for Health and Care Excellence (NICE) has issued guidance about the use of EST for treating plantar fasciitis. NICE states there are no concerns over the safety of EST, but there are uncertainties about how effective the procedure is for treating heel pain. Some studies have reported that EST is more effective than surgery and other non-surgical treatments, while other studies found the procedure to be no better than a placebo (sham treatment).
Preventing heel pain is crucial to avoid pain that can easily interrupt a busy or active lifestyle. Athletes can prevent damage by stretching the foot and calf both before and after an exercise routine. The plantar fascia ligament can be stretched by using a tennis ball or water bottle and rolling it across the bottom of the foot. With regular stretching, the stretching and flexibility of tissue through the foot can be significantly improved, helping to prevent damage and injury. Athletes should also ease into new or more difficult routines, allowing the plantar fascia and other tissue to become accustomed to the added stress and difficulty. Running up hills is also common among athletes in their routines. However, this activity should be reduced since it places an increased amount of stress on the plantar fascia and increases the risk of plantar fasciitis. Maintaining a healthy weight is also an essential heel pain prevention technique. Obesity brings additional weight and stress on the heel of the foot, causing damage and pain in the heel as well as in other areas of the foot.
