My husband also had an intrathecal pain medicine delivery pump implanted, with morphine as the medicine of choice. That also failed to give him relief from his cancer pain. We were told how helpful it would be, with lower side effects from less medicine and maximum benefit. Nothing worked. The surgery to implant the pump left him even worse off and he never really recovered from what was an outpatient procedure. His last two months following the pain pump surgery were not worth living. It was as bad of an outcome as could have been scripted. I am deeply regretful of the entire experience, and we went to two of the country's top experts in his form of cancer.
