How does cancer pain management work?

Pain may come from the tumour, surgery, inflammation, nerve irritation, treatment effects or a separate condition. It can be aching, burning, shooting, cramping or pressure-like, and may be continuous or occur in episodes. The plan depends on the cause, severity, other medicines, kidney and liver function, sleep, mood and your priorities.

Treatment can include non-opioid medicines, opioid pain medicines, drugs for nerve pain, radiotherapy for selected painful areas, physical support and relaxation or counselling techniques. Managing constipation, nausea or drowsiness can make pain treatment easier to continue.

Keep a simple record of where pain occurs, what it feels like, when it starts, what eases it and how it affects walking, eating and sleep. Take medicines exactly as prescribed and do not stop a regular opioid suddenly without advice. Tell the team if relief wears off early, doses cause troublesome sleepiness, or pain prevents ordinary activities; these details guide adjustments.

Contact your cancer team promptly for new severe pain, pain that changes suddenly, or pain with weakness, numbness, trouble walking, loss of bladder or bowel control, fever, repeated vomiting or inability to drink. Sudden breathlessness, chest pain or confusion requires urgent medical help. Persistent bone pain is not proof of a spread of cancer, but it deserves assessment.

Ask what is causing the pain, how quickly each treatment should help, which side effects to report, what to do for breakthrough pain, and whom to contact outside clinic hours.
