Wrong!
The folk from Cochrane asked this question. ‘In adult patients with metastatic bone pain, what is the evidence that bisphosphonates and denosumab are effective and safe in controlling pain?’
http://www.ncbi.nlm.nih.gov/pubmed/27006430
They found that evidence to support an analgesic role for bisphosphonates and denosumab is weak. Bisphosphonates and denosumab appear to be beneficial in preventing pain by delaying the onset of bone pain rather than by producing an analgesic effect per se.
