Bone pain: a difficult puzzle

Bone pain is a symptom not a diagnosis, but the difficult task is to disentangle the etiology. Some locations are more prone to  problems such as back pain or thoracic pain. Another difficult task is to read a plain X-ray because subtle changes can be key for a diagnosis. Bone metastases are a frequent origin of bone pain and usually the clinical behaviour, with  pain with a difficult control and several visits to the emergency department, is the key element for a correct diagnosis.
