The two most common causes of pain in the bottom of the heel, the arch, or both the heel and the arch, are heel spurs and plantar fasciitis. A Heel Spur is a piece of calcium or bone that sticks out from the bottom of the heel bone, and lies within the fibers of the plantar fascia. When walking, the spur digs into the plantar fascia and causes small micro-tears in the plantar fascia. This produces inflammation and pain in the heel, which at times may radiate into the arch.
A heel spur is a bony overgrowth on the bottom of your heel bone. The heel spur is usually a result of an inflamed ligament (plantar fascia) on the bottom of the foot that attaches to the heel bone. Constant abnormal pulling of this ligament irritates the heel bone and the body lays down a bone spur as a protective mechanism. The patient usually complains of pain with the first step in the morning, some relief following activity, but returning after extended amounts of time standing or walking.
You'll typically first notice early heel spur pain under your heel in the morning or after resting. Your heel pain will be worse with the first steps and improves with activity as it warms up. When you palpate the tender area you may feel a tender bony lump. As your plantar fasciitis deteriorates and your heel spur grows, the pain will be present more often.
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
In many cases treatment is non-surgical and can relieve pain, but may take from three months to a year to fully recover. Performing stretching exercises to help relax the tissues in the heel as well as rest, icing, and over-the-counter anti-inflammatory or prescription medications can help ease symptoms. Customized orthotics or shoe inserts to position and cushion your heel can help.
Usually, heel spurs are curable with conservative treatment. If not, heel spurs are curable with surgery, although there is the possibility of them growing back. About 10% of those who continue to see a physician for plantar fascitis have it for more than a year. If there is limited success after approximately one year of conservative treatment, patients are often advised to have surgery.
