I think he is not responding to nivolumab( to be discussed with your doctor for change in the treatment). For better pain relief take morphine. But morphine will aggravate constipation. Fentanyl patch can be applied( slowly release the drug in the body). Constipation will be relieved by taking adequate laxatives( tablet form or syrupfirm or rectal suppositories) and prokinectic agents.
