Patients and doctors often confuse the terms heel spur and plantar fasciitis. While these two diagnoses are related, they are not the same. Plantar fasciitis refers to the inflammation of the plantar fascia--the tissue that forms the arch of the foot. A heel spur is a hook of bone that can form on the heel bone (calcaneus) and is associated with plantar fasciitis. About 70 percent of patients with plantar fasciitis have a heel spur that can be seen on an X-ray. However, many patients without symptoms of pain can have a heel spur. The exact relationship between plantar fasciitis and heel spurs is not entirely understood.
One frequent cause of heel spurs is an abnormal motion and mal-alignment of the foot called pronation. For the foot to function properly, a certain degree of pronation is required. This motion is defined as an inward action of the foot, with dropping of the inside arch as one plants the heel and advances the weight distribution to the toes during walking. When foot pronation becomes extreme from the foot turning in and dropping beyond the normal limit, a condition known as excessive pronation creates a mechanical problem in the foot. In some cases the sole or bottom of the foot flattens and becomes unstable because of this excess pronation, especially during critical times of walking and athletic activities. The portion of the plantar fascia attached into the heel bone or calcaneous begins to stretch and pull away from the heel bone.
Heel spurs result in a jabbing or aching sensation on or under the heel bone. The pain is often worst when you first arise in the morning and get to your feet. You may also experience pain when standing up after prolonged periods of sitting, such as work sessions at a desk or car rides. The discomfort may lessen after you spend several minutes walking, only to return later. Heel spurs can cause intermittent or chronic pain.
Most patients who are suffering with heel spurs can see them with an X-ray scan. They are normally hooked and extend into the heel. Some people who have heel spur may not even have noticeable symptoms, although could still be able to see a spur in an X-ray scan.
Non Surgical Treatment
Rest won?t help you in case of pain from the heel spur. When you get up after sleeping for some time, the pain may get worse. The pain worsens after a period of rest. You will feel pain because the plantar fascia elongates during working which stresses the heel. It is important to see a doctor if you are having consistent pain in you heel. The doctors may advise few or all of the conservative treatments, stretching exercises, shoe recommendations, shoe inserts or orthotic devices, physical therapy, taping or strapping to rest stressed muscles and tendons. There are some over-the-counter medicines available for treatment of heel pain. Acetaminophen (Tylenol), ibuprofen (Advil), or naproxen (Aleve) are some such medicines which can help you to get relief from the pain. In case of biomechanical imbalances causing the pain, a functional orthotic device can help you to get relief. Your doctor may also advise a corticosteroid injection for eliminating the inflammation.
Sometimes bone spurs can be surgically removed or an operation to loosen the fascia, called a plantar fascia release can be performed. This surgery is about 80 percent effective in the small group of individuals who do not have relief with conservative treatment, but symptoms may return if preventative measures (wearing proper footwear, shoe inserts, stretching, etc) are not maintained.
