A bone spur is an abnormal projection of bone from an existing bone. There is not a joint that a bone spur cannot find.
Bone spurs affect millions of people in the form of osteoarthritis, plantar fasciitis, and other bone and tendon disorders.
A bone spur occurs due to chronic damage to a joint, tendon, or bone. Damage comes from high-impact exercise, use over time, or specific traumas.
They often cause pain in surrounding areas and can progress over time without treatment.
