Pain control

Cancer pain can usually be eased. How to describe your pain, the main types of treatment, and common worries about pain medicine.

Rosa: Hi, I'm Rosa. Cancer pain can usually be eased, and you don't have to just put up with it. Let's talk about how to describe your pain and the ways to treat it.

Not everyone with cancer has pain. When pain happens, it can come from the cancer, tests, or surgery. It can also come from side effects like nerve damage or mouth sores. Pain is never something you just have to put up with.

Your care team cannot see your pain, so they rely on you. They may ask you to rate it from 0 (no pain) to 10 (worst pain). Tell them where it is, what it feels like, when it happens, and what makes it better or worse. Pain that is burning, tingling, or shooting is often nerve pain, which may need a different medicine.

Pain is often treated in steps. Mild pain may be eased with acetaminophen or anti-inflammatory medicines. Ask your team which is safe for you, since some can hide a fever or raise bleeding risk. Stronger pain may need an opioid, such as morphine or oxycodone. Other medicines can help too, such as some seizure or depression medicines for nerve pain, and steroids for swelling.

For pain that is there most of the day, a long-acting medicine taken on a schedule often works best. A short-acting medicine is used for breakthrough pain, a flare that comes on top of your usual pain. Take pain medicine before pain gets severe. It is harder to control once it is very bad.

Other treatments can help. Radiation can ease pain from cancer in the bones, often in one or a few visits. Nerve blocks, procedures to strengthen a broken spine bone, and pain pumps may help when pills are not enough. Heat, cold, gentle movement, massage, relaxation, and music may also help.

A palliative care or pain specialist team can be a great help. They are experts in finding the right mix of treatments with the fewest side effects.

Myth: opioids always lead to addiction

Fact: when taken as prescribed for cancer pain, addiction is uncommon. Needing a higher dose over time does not mean you are addicted. If you have had a substance use problem, tell your team so they can plan safely. You still deserve good pain control.

Constipation

Opioids almost always cause constipation. Ask your team about a daily laxative when you start an opioid. Do not wait until you are blocked up.

Other side effects

Sleepiness and nausea often get better after a few days. Itching can happen. Do not drive until you know how the medicine affects you. These side effects are not the same as an allergy.

Safety at home

Store pain medicine in a locked place away from children, pets, and visitors. Do not share it. Ask about naloxone, a nasal spray that can reverse an opioid overdose. Teach a family member how to use it. Ask your pharmacy how to get rid of leftover medicine.

Do not mix without asking

Alcohol, sleep pills, and anxiety medicines can be dangerous with opioids. Check with your team before taking anything else.

Call your care team if

Pain is new or much worse, or your medicine is not working. You have not had a bowel movement in 3 days. You are too sleepy or confused. Call right away or go to the emergency room for new back pain with leg weakness, numbness, or trouble controlling your bladder or bowels. If someone is very hard to wake or breathing very slowly, give naloxone if you have it and call 911.

Questions to ask

What is causing my pain? What should I take for breakthrough pain? How do I prevent constipation? Can I see a palliative care or pain specialist?

• Keep a simple pain diary: score, time, what you took, and whether it helped.
• Bring your pain medicine bottles or a list to every visit.
• Start a bowel plan when you start an opioid.
• Store opioids locked and ask about naloxone.
• Make sure you will not run out, especially before weekends and holidays.
