Osteomyelitis without fever: what to know

Osteomyelitis can occur without fever, so persistent bone pain, swelling, drainage or a slow-healing wound still needs medical assessment. A normal temperature cannot confirm that bone is clear of infection, particularly when symptoms are localised or have developed gradually.

Fever is a whole-body response and may not appear when infection is contained in one area, develops slowly, or affects someone whose immune response is reduced. Pain, warmth, tenderness, redness, swelling, reduced movement and drainage can provide more useful local clues. Clinicians combine the examination with blood tests, imaging and sometimes a sample rather than using temperature alone.

Book a prompt review for ongoing focal pain, an ulcer, drainage or a wound that is not closing. Keep the area clean and covered, avoid picking at the wound, and do not start leftover antibiotics. Note recent surgery, injury, dental work, implanted hardware and any conditions affecting circulation or immunity. Treatment may include prescribed antimicrobial medicine, wound care and removal of infected tissue; Bone Grafting may be relevant if a treated defect needs reconstruction.

Seek urgent care for rapidly spreading redness, sudden severe pain, pus, skin colour change, new numbness or weakness, inability to use the limb, confusion, faintness or chills. Emergency assessment is also appropriate when a deep wound follows an injury or when symptoms worsen despite treatment, even if repeated temperature checks remain normal.

Ask what findings make infection more or less likely, whether imaging or a sample is appropriate, and how circulation and nearby tissue will be checked. Ask how to monitor the wound at home and which changes require immediate reassessment.
