Implantable Pain Pumps: Until recently, implantable pain pumps were reserved for cancer pain, and, while the popularity of these systems has increased for chronic non- malignant pain, there can be formidable side effects. These include urinary retention, constipation, catheter tip granulomas, and equipment failure precipitating acute withdrawal. Therefore, pain pumps can only be recommended when all other viable options have failed and side effects from oral medications have become intolerable. Like spinal cord stimulators, pain pumps may preclude later evaluation with MRI.
