The patient with myeloma Challenging patients, challenging pain Age Co-morbidities Multiple causes of pain Cancer pain vs chronic pain Setting realistic expectations Assessment and monitoring
Assessing pain Site Radiation Onset Time intensity Character Severity The (very, very) basics…. Site Radiation Onset Time intensity Character Severity Aggravating factors Relieving factors Associated factors
Assessing pain What does it mean? “My 2 is your 10” 0-10 pain score What does it mean? “My 2 is your 10” What’s a good reduction? What is acceptable? What are we measuring? Functional ability Other scoring systems
Management options Bisphosphonates, radiotherapy and balloon kyphoplasty/vertebroplasty Pharmacological options Paracetamol Opioids Calcium channel modulators (gabapentin, pregabalin) (NSAIDs) Non-Pharmacological options Exercise Psychological support Complimentary therapies
Opioids: Counsel, titrate, negotiate “I don't want to become addicted to it” “I might overdose if take too much” Drug driving legislation, March 2015 Morphine, codeine, diamorphine, benzodiazepines
Opioids: Counsel, titrate, negotiate Low and slow! Rapid escalation of pain = rapid escalation of analgesia! How much pain is acceptable? Follow-up and side effects

If still in pain, take a second dose and wait another hour. If still in pain, take a third dose and wait another hour. If still in pain, call for advice.”
Beware….. Rapidly absorbed fentanyl Constipation Sedation Nausea Hypogonadic hypogonadism!
Take home points One size does not fit all Decide on a standard assessment for pain in your service Assess functional ability as well as a pain score Set realistic expectations of pain relief Opioid selection is individual, based on science Consider endocrine suppression as a cause of fatigue
