Heel spurs

What are heel spurs?

A small bony growth is also called a heel spur. It can be seen on X-rays of the heel. It is called a heel spur because it resembles a small spur that you find on a riding boot. The term heel spur is often used as a general term for pain in and around the heel, but it is actually an irritation or inflammation of a mucous sac found under the heel bone, or inside the tendon that attaches under the heel.

Why does a heel spur occur?

When the foot pad under the heel bone is overloaded, a heel spur occurs. This is due to prolonged overload of the arch tendon. The arch tendon originates from the heel and runs under the foot towards the toes. It absorbs shock when you step down. Running and walking on hard surfaces are typical causes of overload. It can also be caused by wearing shoes without the right shock absorption. If you suffer from cavus, flat feet or have arthritis, heel spurs are seen more often.

What are the symptoms of heel spurs?

Pain under or on the inside of the heel, especially when you put weight on the foot when standing, walking or running, is a common symptom. You may experience pain radiating into the foot and sole of the foot. The pain is worst in the morning and it may feel like you have to warm up your foot before you can move forward and dare to take a real step on your foot.
