What does pain that wakes you at night feel like with osteomyelitis?

Most people with Osteomyelitis notice pain that wakes you at night in a focused area, with tenderness or pain when the nearby limb is used. The skin over the bone may be warm, red, or swollen, and movement can become difficult. Fever, chills, tiredness, or feeling generally unwell may occur, although symptoms vary. Night pain is not specific to infection, so a clinician needs to consider the history, examination, and any wound or recent procedure.

Contact a healthcare professional promptly if deep bone pain is persistent, especially when it follows a wound, operation, injection, or skin infection. Keep any wound clean and covered as advised, avoid pressing or heavily loading the painful area, and do not start leftover antibiotics. A clinician may arrange blood tests, imaging, or a sample to guide treatment.

Seek urgent care for fever with worsening bone pain, rapidly spreading redness, pus or foul drainage, severe swelling, confusion, faintness, or difficulty moving the affected limb. People with diabetes, poor circulation, or a weakened immune system should seek advice early when a wound and deep pain occur together.

Could an infection be affecting the bone? Is there a wound or procedure that changes the risk? Which tests would clarify the cause? How should I protect the limb while waiting for treatment?
