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.
Plantar fasciitis can come from a number of underlying causes. Finding the precise reason for the heel pain is sometimes difficult. As you can imagine, when the foot is on the ground a tremendous amount of force (the full weight of the body) is concentrated on the plantar fascia. This force stretches the plantar fascia as the arch of the foot tries to flatten from the weight of your body. This is just how the string on a bow is stretched by the force of the bow trying to straighten. This leads to stress on the plantar fascia where it attaches to the heel bone. Small tears of the fascia can result. These tears are normally repaired by the body. As this process of injury and repair repeats itself over and over again, a bone spur (a pointed outgrowth of the bone) sometimes forms as the body's response to try to firmly attach the fascia to the heelbone. This appears on an X-ray of the foot as a heel spur. Bone spurs occur along with plantar fasciitis but they are not the cause of the problem. As we age, the very important fat pad that makes up the fleshy portion of the heel becomes thinner and degenerates (starts to break down). This can lead to inadequate padding on the heel. With less of a protective pad on the heel, there is a reduced amount of shock absorption. These are additional factors that might lead to plantar fasciitis. Some physicians feel that the small nerves that travel under the plantar fascia on their way to the forefoot become irritated and may contribute to the pain. But some studies have been able to show that pain from compression of the nerve is different from plantar fasciitis pain. In many cases, the actual source of the painful heel may not be defined clearly. Other factors that may contribute to the development of plantar fasciitis include obesity, trauma, weak plantar flexor muscles, excessive foot pronation (flat foot) or other alignment problems in the foot and or ankle, and poor footwear.
See your doctor immediately if you have Severe pain and swelling near your heel. Inability to bend your foot downward, rise on your toes or walk normally. Heel pain with fever, numbness or tingling in your heel. Severe heel pain immediately after an injury. Schedule an office visit if you have. Heel pain that continues when you're not walking or standing. Heel pain that lasts more than a few weeks, even after you've tried rest, ice and other home treatments.
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
Treatment options for plantar fasciitis include custom prescription foot orthoses (orthotics), weight loss when indicated, steroid injections and physical therapy to decrease the inflammation, night-splints and/or cast boots to splint and limit the stress on the plantar fascia. Orthotripsy (high frequency ultra-sonic shock waves) is also a new treatment option that has been shown to decrease the pain significantly in 50 to 85 percent of patients in published studies. Surgery, which can be done endoscopically, is usually not needed for over 90 percent of the cases of plantar fasciitis. (However, when surgery is needed, it is about 85 percent successful.) Patients who are overweight do not seem to benefit as much from surgery. Generally, plantar fasciitis is a condition people learn to control. There are a few conditions similar to plantar fascia in which patients should be aware. The most common is a rupture of the plantar fascia: the patient continues to exercise despite the symptoms and experiences a sudden sharp pain on the bottom of the heel and cannot stand on his or her toes, resulting in bruising in the arch. Ruptures are treated very successfully by immobilization in a cast boot for two to six weeks, a period of active rest and physical therapy. Another problem with prolonged and neglected plantar fasciitis is development of a stress fracture from the constant traction of this ligament on the heel bone. This appears more common in osteoporotic women, and is also treated with cast boot immobilization. The nerves that run along the heel occasionally become inflamed by the subsequent thickening and inflammation of the adjacent plantar fascia. These symptoms often feel like numbness and burning and usually resolve with physical therapy and injections. Patients should also be aware that heel numbness can be the first sign of a back problem.
Surgery is a last resort in the treatment of heel pain. Physicians have developed many procedures in the last 100 years to try to cure heel pain. Most procedures that are commonly used today focus on several areas, remove the bone spur (if one is present), release the plantar fascia (plantar fasciotomy), release pressure on the small nerves in the area. Usually the procedure is done through a small incision on the inside edge of the foot, although some surgeons now perform this type of surgery using an endoscope. An endoscope is a tiny TV camera that can be inserted into a joint or under the skin to allow the surgeon to see the structures involved in the surgery. By using the endoscope, a surgeon can complete the surgery with a smaller incision and presumably less damage to normal tissues. It is unclear whether an endoscopic procedure for this condition is better than the traditional small incision. Surgery usually involves identifying the area where the plantar fascia attaches to the heel and releasing the fascia partially from the bone. If a small spur is present this is removed. The small nerves that travel under the plantar fascia are identified and released from anything that seems to be causing pressure on the nerves. This surgery can usually be done on an outpatient basis. This means you can leave the hospital the same day.
heel pain treatment
You can reduce the risk of heel pain in many ways, including. Wear shoes that fit you properly with a firm fastening, such as laces. Choose shoes with shock-absorbent soles and supportive heels. Repair or throw out any shoes that have worn heels. Always warm up and cool down when exercising or playing sport, include plenty of slow, sustained stretches. If necessary, your podiatrist will show you how to tape or strap your feet to help support the muscles and ligaments. Shoe inserts (orthoses) professionally fitted by your podiatrist can help support your feet in the long term.
