What are the signs and symptoms of diffuse idiopathic skeletal hyperostosis (DISH)?

Diffuse idiopathic skeletal hyperostosis often causes no symptoms, though stiffness and pain along affected ligaments can occur. The signs and symptoms experienced by individuals with diffuse idiopathic skeletal hyperostosis depend on which part of the body is affected. The upper portion of the back (thoracic spine) is most commonly affected. Some people experience diffuse idiopathic skeletal hyperostosis beyond the spine in areas such as their heels, ankles, knees, hips, shoulders, elbows and hands.[1] The calcification which occurs in this condition can lead to bone spurs.[2] Other signs and symptoms may include:[1]
  • Stiffness which is most noticeable in the morning.
  • Pain when pressure is applied to the affected area. 
  • Loss of lateral range of motion. 
  • Difficulty swallowing or a hoarse voice, particularly if the cervical spine is affected.
