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. 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.
Heel pain is most often the result of overuse. Rarely, it may be caused by an injury. Your heel may become tender or swollen from, shoes with poor support or shock absorption. Running on hard surfaces, like concrete. Running too often. Tightness in your calf muscle or the Achilles tendon. Sudden inward or outward turning of your heel. Landing hard or awkwardly on the heel. Conditions that may cause heel pain include. When the tendon that connects the back of your leg to your heel becomes swollen and painful near the bottom of the foot. Swelling of the fluid-filled sac (bursa) at the back of the heel bone under the Achilles tendon (bursitis). Bone spurs in the heel. Swelling of the thick band of tissue on the bottom of your foot (plantar fasciitis). Fracture of the heel bone that is related to landing very hard on your heel from a fall (calcaneus fracture).
Pain in the bottom of the heel is the most common symptom. The pain is often described as a knife-like, pinpoint pain that is worse in the morning and generally improves throughout the day. By the end of the day the pain may be replaced by a dull ache that improves with rest. The pain results from stretching the damaged tissues. For the same reason atheletes’ pain occurs during beginning stages of exercise and is relieved over time as warm-up loosens the fascia. Plantar fasciitis onset is usually gradual, only flaring up during exercise. If pain is ignored, it can eventually interfere with walking and overall, plantar fasciitis accounts for about ten percent of all running injuries.
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
Once diagnosed, treatment for plantar fasciitis may include one or more of the following: advice on footwear, in particular use of arch-supportive footwear; avoid walking barefoot; stretching exercises, shoe modifications such as heel pads, taping and strapping, anti-inflammatories and orthotic devices to correct abnormal foot mechanics. Injection therapy with corticosteroids is only advisable if all the conservative treatment methods mentioned above have been exhausted due to undesired effects implicated with steroid infusion in the heels.
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.
Wear properly fitting shoes. Place insoles or inserts in your shoes to help control abnormal foot motion. Maintain a healthy weight. Exercise and do foot stretches as they have been shown to decrease the incidence of heel pain.
