chronic recurrent multifocal osteomyelitis

Chronic non bacterial osteomyelitis (CNO), also known as chronic recurrent multifocal osteomyelitis (CRMO), is a condition where multiple areas of bones become painful and swollen. It is categorized as an autoinflammatory syndrome, which means the body’s immune system triggers inflammation in the absence of a bacterial infection. The swelling and pain are most commonly seen in the metaphyses of long bones, as well as in the pelvis, shoulder girdle, and spine. The inflammation can recur over time, leading to periods of flare-ups and improvement.

People with this condition often experience localized bone pain, swelling, and tenderness. These symptoms are usually seen in the long bones, pelvis, shoulder, and spine. The bone pain may come and go over time, contributing to the recurrent nature of this condition.

Chronic non bacterial osteomyelitis is considered an autoinflammatory syndrome. This means that the inflammation likely results from an abnormal response of the immune system. Information about the exact triggers and factors is limited based on the available sources.
