A heel spur is caused by the displacement of calcium on the bone that forms on the underside of the heel, it may be one small bony protrusion or a collection of tiny, irregularly shaped growths on the bone of the heel, which is called the calcaneum. Heel spurs are sometimes painful, described as a knife digging into the heel and other times, a heel spur goes unnoticed and is only detected by an X-ray.
The pain caused by heel spurs can be a sharp, stabbing pain when using the foot after a long period of rest. Sometimes it then reduces to a dull throb that can worsen when engaging in activities like jogging or jumping. People sometimes describe the pain of heel spurs and plantar fasciitis as a pin sticking into the bottom of the foot when they first stand up in the morning, this pain later turns into a bearable ache. The cause of the pain is generally not the heel spur itself, but the soft-tissue buildup associated with it. People often complain that the sharp pain returns after they stand up following sitting for a prolonged period of time.
Heel spurs often cause no symptoms. But heel spurs can be associated with intermittent or chronic pain, especially while walking, jogging, or running, if inflammation develops at the point of the spur formation. In general, the cause of the pain is not the heel spur itself but the soft-tissue injury associated with it. Many people describe the pain of heel spurs and plantar fasciitis as a knife or pin sticking into the bottom of their feet when they first stand up in the morning, a pain that later turns into a dull ache. They often complain that the sharp pain returns after they stand up after sitting for a prolonged period of time.
Your doctor will discuss your medical history and will examine your foot and heel for any deformities and inflammation (swelling, redness, heat, pain). He/she will analyze your flexibility, stability, and gait (the way you walk). Occasionally an x-ray or blood tests (to rule out diseases or infections) may be requested.
Non Surgical Treatment
Initially, treatment usually consists of a combination of ice therapy, stretching exercises to improve flexibility (especially in the mornings), anti-inflammatory medications, and physical therapy. Most patients will also need custom-molded orthotics to help control the motion in the foot and arch, which takes the strain off the plantar fascia. If the pain continues, a cortisone injection may be used to calm the severe swelling and pain. There may the need for a night splint to maintain a stretch in the plantar fascia throughout the night.
Heel spur surgery should only be considered after less invasive treatment methods have been explored and ruled insufficient. The traditional surgical approach to treating heel spurs requires a scalpel cut to the bottom of the food which allows the surgeon to access the bone spur. Endoscopic plantar fasciotomies (EPF) involve one or two small incisions in the foot which allow the surgeon to access and operate on the bone spur endoscopically. Taking a surgical approach to heel spur treatment is a topic to explore with a foot and ankle specialist.
