A heel spur occurs when calcium deposits build up on the underside of the heel bone, a process that usually occurs over a period of many months. Heel spurs are often caused by strains on foot muscles and ligaments, stretching of the plantar fascia, and repeated tearing of the membrane that covers the heel bone. Heel spurs are especially common among athletes whose activities include large amounts of running and jumping. Heel spurs often cause no symptoms but can be associated with intermittent pain, especially while walking, jogging, or running. Sharp pain in the heel can also be experienced when standing after sitting for a long period of time. Heel spurs can be a result of plantar fasciitis.
Bone spurs can occur all over the body including the spine, shoulders, hands, hips and feet. The feet are a common place to find them. A heel spur happens when the body tries to mend itself. Building extra bone is one way your body tries to correct a weakness. Wearing shoes that are too tight in the heel can cause bone spurs. More women than men get heel spurs because of the kinds of shoes they wear. Athletes who stress their feet and legs routinely are also prone to heel spurs. Being overweight can also indirectly cause heel spurs by over-exerting the plantar fascia. Some heel spurs are caused by the aging process, in which the cartilage covering the ends of bones wears away. This process can lead to pain, swelling and spur formation. Stress-related problems with the plantar fascia frequently lead to heel spurs.
It is important to be aware that heel spurs may or may not cause symptoms. Symptoms are usually related to the plantar fasciitis. You may experience significant pain and it may be worse in the morning when you first wake up or during certain physical activities such as, walking, jogging, or running.
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
There are various ways to treat heel spurs. The first is to rest and apply ice to the afflicted area. Shoe inserts and night splints can also treat plantar fasciitis, and in turn, heels spurs. Unless you have stomach sensitivities, you may want to consider taking over-the-counter anti-inflammatory medication such as naprosyn to lower the swelling. A physical therapist can recommend gentle exercises and stretches to relax the tissue around the heel bone to relieve the tension. Even with these treatments, a stubborn heel spur may not go away. A physical therapist may decide to inject cortisone into the area to decrease inflammation, but that can cause other problems such as plantar fascial rupture and fat pad atrophy. Extracorporeal shock wave therapy is also an option, which uses energy pulses to apply microtrauma around the heel spur. Surgery is also an option but is not suggested unless the heel spur lasts more than a year. To prevent heel spurs from returning, shoe inserts can relieve the pressure on the plantar fascia. Also continue the recommended stretches and exercises.
When chronic heel pain fails to respond to conservative treatment, surgical treatment may be necessary. Heel surgery can provide pain relief and restore mobility. The type of procedure used is based on examination and usually consists of releasing the excessive tightness of the plantar fascia, called a plantar fascia release. The procedure may also include removal of heel spurs.
