Heel spurs are usually under the heel and are generally caused by excessive forces acting on the bone. By far the most common cause of heel spurs is abnormal biomechanics - often the same biomechanics that cause plantar fasciitis. Heel spurs are not a direct cause of heel pain. They grow in response to the forces of the soft tissue pulling on the bone. Any condition where the foot has excessive motion can produce tension within the soft tissues acting on the heel.
A heel spur can develop when there is an abundance of calcium creating a deposit in the calcaneus, or heel bone. Over time, this deposit grows to create an outcropping under the heel that extends into the foot. The result is a protrusion that leads to foot pain when pressure is applied, and in some cases, even during rest.
Heel spurs are most noticeable in the morning when stepping out of bed. It can be described as sharp isolated pain directly below the heel. If left untreated heel spurs can grow and become problematic long-term.
Diagnosis is made using a few different technologies. X-rays are often used first to ensure there is no fracture or tumor in the region. Then ultrasound is used to check the fascia itself to make sure there is no tear and check the level of scar tissue and damage. Neurosensory testing, a non-painful nerve test, can be used to make sure there is not a local nerve problem if the pain is thought to be nerve related. It is important to remember that one can have a very large heel spur and no plantar fasciitis issues or pain at all, or one can have a great deal of pain and virtually no spur at all.
Non Surgical Treatment
The most important part of treatment is to rest. Do not undertake activities which hurt the foot or aggravate symptoms as will only cause painful symptoms to persist. Apply an ice pack regularly for 10 minutes at a time every hour initially to reduce pain and inflammation of the surrounding tissues. As symptoms subside frequency of application can reduce to 2 or 3 times per day. Exercises and stretches to keep the foot and ankle strong and mobile are important as long as pain allows. Stretching the plantar fascia is important, especially if symptoms are worse in the morning. A plantar fasciitis night splint is excellent for stretching and preventing the plantar fascia tightening up over night. Anti-Inflammatory medicine (e.g. ibuprofen) may be prescribed by a doctor but always check with a medical professional first as taking some medications such as ibuprofen should not be done if the patient has asthma. Shoe inserts can help to take the pressure off of the spur and reduce pain. If these treatments do not significantly ease the symptoms then surgery may be an option.
More than 90 percent of people get better with nonsurgical treatments. If conservative treatment fails to treat symptoms of heel spurs after a period of 9 to 12 months, surgery may be necessary to relieve pain and restore mobility. Surgical techniques include release of the plantar fascia, removal of a spur. Pre-surgical tests or exams are required to identify optimal candidates, and it's important to observe post-surgical recommendations concerning rest, ice, compression, elevation of the foot, and when to place weight on the operated foot. In some cases, it may be necessary for patients to use bandages, splints, casts, surgical shoes, crutches, or canes after surgery. Possible complications of heel surgery include nerve pain, recurrent heel pain, permanent numbness of the area, infection, and scarring. In addition, with plantar fascia release, there is risk of instability, foot cramps, stress fracture, and tendinitis.
