Heel pain is most often caused by plantar fasciitis, a condition that is sometimes also called heel spur syndrome when a spur is present. Heel pain may also be due to other causes, such as a stress fracture, tendonitis, arthritis, nerve irritation, or, rarely, a cyst. Because there are several potential causes, it is important to have heel pain properly diagnosed. A foot and ankle surgeon is able to distinguish between all the possibilities and determine the underlying source of your heel pain.What Is Plantar Fasciitis? Plantar fasciitis is an inflammation of the band of tissue (the plantar fascia) that extends from the heel to the toes. In this condition, the fascia first becomes irritated and then inflamed, resulting in heel pain.
A flattening or overstretching of your plantar fascia can cause microscopic tears, inflammation, and a burning sensation. While developing slowly, there may be a sudden severe event sometimes occurring in only one foot at a time. Plantar Faciitis can affect people of all ages and backgrounds. Some contributing factors include age, weight-bearing activities, sudden increase in physical activity, improper shoes, excess weight or a recent weight gain (as little as 5 pounds), and poor biomechanics (flat feet, high arches or unnatural gait).
Pain in the heel can be caused by many things. The commonest cause is plantar fascitis. Other causes include, being overweight, constantly being on your feet, especially on a hard surface like concrete and wearing hard-soled footwear, thinning or weakness of the fat pads of the heel, injury to the bones or padding of the heel, arthritis in the ankle or heel (subtalar) joint, irritation of the nerves on the inner or outer sides of the heel, fracture of the heel bone (calcaneum).
The diagnosis of plantar fasciitis is generally made during the history and physical examination. There are several conditions that can cause heel pain, and plantar fasciitis must be distinguished from these conditions. Pain can be referred to the heel and foot from other areas of the body such as the low back, hip, knee, and/or ankle. Special tests to challenge these areas are performed to help confirm the problem is truly coming from the plantar fascia. An X-ray may be ordered to rule out a stress fracture of the heel bone and to see if a bone spur is present that is large enough to cause problems. Other helpful imaging studies include bone scans, MRI, and ultrasound. Ultrasonographic exam may be favored as it is quick, less expensive, and does not expose you to radiation. Laboratory investigation may be necessary in some cases to rule out a systemic illness causing the heel pain, such as rheumatoid arthritis, Reiter's syndrome, or ankylosing spondylitis. These are diseases that affect the entire body but may show up at first as pain in the heel.
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).
You can help to prevent heel pain by maintaining a healthy weight, by warming up before participating in sports and by wearing shoes that support the arch of the foot and cushion the heel. If you are prone to plantar fasciitis, exercises that stretch the Achilles tendon (heel cord) and plantar fascia may help to prevent the area from being injured again. You also can massage the soles of your feet with ice after stressful athletic activities. Sometimes, the only interventions needed are a brief period of rest and new walking or running shoes.
