When to worry about persistent bone pain with osteomyelitis

Osteomyelitis is an infection involving bone. It can cause deep pain, tenderness, swelling, warmth, redness, drainage from a wound, or difficulty using the nearby limb. Symptoms may improve gradually with treatment, but persistent or returning pain can mean the infection needs reassessment. A recent operation, wound, injury, or implanted material may affect how clinicians investigate and treat it.

Take antibiotics or other prescribed treatment exactly as directed, and do not stop early unless the treating clinician tells you to. Keep the area clean according to your care instructions and watch for expanding redness, drainage, swelling, or a wound that is not healing. Contact your clinician if pain is not improving, returns after improvement, or makes movement harder. Do not massage an inflamed area or self-treat with leftover antibiotics.

Get urgent medical help for fever with chills, confusion, faintness, rapidly spreading redness or swelling, pus, severe escalating pain, or feeling suddenly very unwell. Seek immediate care if the affected limb becomes weak, numb, cold, or difficult to move. A new inability to bear weight or severe pain after a minor movement also needs rapid assessment for possible bone damage.

Ask how you will know treatment is working, when repeat examination or imaging is needed, how to care for any wound, and whom to contact if symptoms return after clinic hours.
