Other presentations
Symptoms of osteomyelitis vary with the duration of the disease and may have a gradual onset over several days. A patient with acute osteomyelitis typically presents as acutely unwell, with bone pain in the region affected along with tenderness, warmth, and swelling.[1]Glaudemans AWJM, Jutte PC, Cataldo MA, et al. Consensus document for the diagnosis of peripheral bone infection in adults: a joint paper by the EANM, EBJIS, and ESR (with ESCMID endorsement). Eur J Nucl Med Mol Imaging. 2019 Apr;46(4):957-70.

Pain may occur with or without movement. This classic presentation does not occur in all cases.[4]Woods CR, Bradley JS, Chatterjee A, et al.

Some sites, such as the vertebrae or pelvis, may present a diagnostic challenge with a systemically unwell patient displaying signs of sepsis but without clear localizing signs.
Chronic osteomyelitis generally has a longer duration of symptoms. The pain may be less severe, with minimal fever and fewer constitutional symptoms. There is often a history of a discharging sinus or signs of old healed sinuses, or soft-tissue abscesses. Patients may have lived with discharging sinuses for years, having previously been told that there is nothing that can be done for their problem.[4]Woods CR, Bradley JS, Chatterjee A, et al.

Chronic osteomyelitis may cause long-term ill health with weight loss, malaise, fatigue, chills, low-grade fever, chronic pain, or depressed mood.[4]Woods CR, Bradley JS, Chatterjee A, et al.

Acute systemic upset is less common but pyrexia, sweating attacks, and anorexia are associated with flare-ups of the disease.
