The short answer
Osteomyelitis is an infection of bone. Pain with warmth, swelling, redness or feeling unwell needs prompt medical assessment, particularly after an injury or surgery. Early treatment matters; symptoms should not be managed with leftover antibiotics at home.
Understanding the problem
Risk can be higher with diabetes, wounds, fractures or a weakened immune system. Children may avoid using a limb. Assessment may include blood tests, imaging and samples to understand the infection and guide treatment.
Care and next steps
Treatment commonly involves antibiotics, sometimes in hospital. Surgery may be needed to drain pus or remove damaged tissue. The medicine and duration depend on the individual case, so follow the treating team's plan and attend follow-up even when symptoms improve.
Prepare for your consultation
Tell the clinician about previous operations, implants, open wounds and any earlier infection. Bring culture results and a list of antibiotics already taken if available. Record medication allergies accurately. If the concern involves an old fracture, the original discharge papers can help, but do not delay urgent assessment while searching for them. Ask how treatment response will be checked.
Common questions
Can a child have a bone infection without a high fever?
Yes. Refusing to use a limb or an unexplained limp can also need prompt assessment.
