The plantar fascia is connective tissue on the sole of your foot. When the arch of the foot is not properly supported, the plantar fascia can stretch and pull away from the heel area. When the plantar fascia pulls away from the heel, calcium deposits form in its absence. These calcium deposits are called heel spurs and can be very painful.
Heel Spurs develop when the plantar fascia is excessively and repetitively pulled away from the heel bone. In many cases, a heel spur can develop along with plantar fasciitis, but can also occur by itself. Heel spurs often develop in middle-aged patients, but can also occur in younger people as well. Athletes are especially prone to heel spur due to the regular stress on their heels.
The vast majority of people who have heel spurs feel the asscociated pain during their first steps in the morning. The pain is quite intense and felt either the bottom or front of the heel bone. Typically, the sharp pain diminishes after being up for a while but continues as a dull ache. The pain characteristically returns when first standing up after sitting for long periods.
Because the diagnosis of heel spurs can be confused with tarsal tunnel syndrome (as described earlier), most surgeons advocate performing a tarsal tunnel release (or at least a partial tarsal tunnel release) along with the plantar fascia release. This surgery is about 80percent successful in relieving pain in the small group of patients who do not improve with conservative treatments.
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.
Approximately 2% of people with painful heel spurs need surgery, meaning that 98 out of 100 people do well with the non-surgical treatments previously described. However, these treatments can sometimes be rather long and drawn out, and may become considerably expensive. Surgery should be considered when conservative treatment is unable to control and prevent the pain. If the pain goes away for a while, and continues to come back off and on, despite conservative treatments, surgery should be considered. If the pain really never goes away, but reaches a plateau, beyond which it does not improve despite conservative treatments, surgery should be considered. If the pain requires three or more injections of "cortisone" into the heel within a twelve month period, surgery should be considered.
