Chronic Multifocal Osteomyelitis: Symptoms, Diagnosis and Care

It is also called chronic nonbacterial osteitis. Despite the name, it is distinct from typical bacterial bone infection, and antibiotics do not treat the underlying sterile inflammation unless a separate infection is found.

Inflammation may affect one or several sites and can quieten and flare again. Common experiences include deep focal bone pain, tenderness, swelling, limping, or reduced use of a limb. Spinal or jaw involvement requires particular attention because local damage can have greater consequences.

Diagnosis is based on the clinical pattern together with imaging and blood tests, while excluding infection, tumour, fracture, and other inflammatory disease. Magnetic resonance imaging can reveal symptomatic and silent sites. A biopsy may be recommended when the pattern is uncertain.

Specialist care is commonly coordinated through paediatric rheumatology or a bone health team. Keep a record of pain location, swelling, walking changes, sleep disruption, skin symptoms, bowel symptoms, and medicine effects because these details can reveal a flare or an associated inflammatory condition.

Follow the prescribed anti-inflammatory plan and attend monitoring for medicines and bone lesions. During active pain, adapt impact activity without stopping all movement. Physiotherapy can preserve comfortable mobility, strength, and participation while avoiding heavy loading through an inflamed site.

Contact the treating team promptly for new severe focal pain, increasing swelling, a new limp, inability to use a limb, or pain over the spine or jaw. New weakness, numbness, or bladder or bowel disturbance alongside back pain needs urgent assessment.

Fever, spreading redness, drainage, or marked illness should be assessed urgently because infection can resemble a flare and needs different treatment. A new injury with deformity or inability to bear weight also requires timely evaluation.

Ask which bones are active, how response will be monitored, what medicine side effects require contact, and which activities should be modified. Clarify whether whole-body imaging, blood monitoring, bone health assessment, or review by another specialty is appropriate for the current pattern.
