There are approximately 75 different causes of heel pain. At least 80% of all heel pain is due to heel spurs. A heel spur contains calcium, but cannot truly be called a calcium deposit. Bone spurs, whether they are on the heel or on any other bone of the body, are true bone -- they are true enlargements of the bone and may be sharp and pointed, or round and knobby. Since bone spurs are true bone, they contain calcium just like regular bones, but are not pure calcium deposits.
When a patient has plantar fasciitis, the plantar fascia becomes inflamed and degenerative (worn out)--these abnormalities can make normal activities quite painful. Symptoms typically worsen early in the morning after sleep. At that time, the plantar fascia is tight so even simple movements stretch the contracted plantar fascia. As you begin to loosen the plantar fascia, the pain usually subsides, but often returns with prolonged standing or walking.
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.
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
Get some rest. You need to stay off of your aching foot as much as possible for at least a week. Think about possible causes of the problem while you're resting and figure out how you can make some changes. Some actions that can contribute to heel spurs include running too often or running on hard surfaces such as concrete, tight calf muscles, shoes with poor shock absorption. Ease back into your activities. In many cases, you'll be in too much pain to go ahead with a strenuous exercise routine that puts pressure or impact on your heel. Listen to your body and switch to different activities such as swimming or riding a bike until your heel spurs improve.
Surgery to correct for heel spur syndrome is a common procedure which releases plantar fascia partially from its attachment to the calcaneous (heel bone). This part of the surgery is called a plantar fasciotomy due to the fact the fascia is cut. This is most often done through an open procedure as any heel spur or bursa can be removed at the same time. If the spur is not removed during the surgery, it will probably be just as successful, as the large spur is not the true problem. Some physicians use an endoscopic approach (EPF) where a small camera aids the physician during surgery with typically smaller incisions on each side of your foot.
There are heel spur prevention methods available in order to prevent the formation of a heel spur. First, proper footwear is imperative. Old shoes or those that do not fit properly fail to absorb pressure and provide the necessary support. Shoes should provide ample cushioning through the heel and the ball of the foot, while also supporting the arch. Wearing an orthotic shoe insert is one of the best ways to stretch the plantar fascia and prevent conditions such as heel spurs. Stretching the foot and calf is also helpful in preventing damage. Athletes in particular should make sure to stretch prior to any physical activity. Stretching helps prevent heel spurs by making tissue stronger as well as more flexible. In addition, easing into a new or increasingly difficult routine should be done to help avoid strain on the heel and surrounding tissue.
