Overview

Diffuse idiopathic skeletal hyperostosis (DISH) is a bony hardening of ligaments in areas where they attach to your spine.

Also known as Forestier's disease, this condition might not cause symptoms or require treatment. If it does cause symptoms, the most common are mild to moderate pain and stiffness in your upper back. DISH can also affect your neck and lower back, and some people have DISH in other areas, such as shoulders, elbows, knees and heels.

DISH can be progressive. As it worsens, it can cause serious complications.
