What is pain?
Pain is an uncomfortable feeling that tells you something may be wrong in your body. Pain is your body's way of sending a warning to your brain. Your spinal cord and nerves provide the pathway for messages to travel to and from your brain and the other parts of your body.
Receptor nerve cells in and beneath your skin sense heat, cold, light, touch, pressure, and pain. You have thousands of these receptor cells, most sense pain and the fewest sense cold. When there is an injury to your body--in this case surgery--these tiny cells send messages along nerves into your spinal cord and then up to your brain. Pain medicine blocks these messages or reduces their effect on your brain.
Sometimes pain may be just a nuisance, like a mild headache. At other times, such as after an operation, pain that doesn't go away- -even after you take pain medicine--may be a signal that there is a problem. After your operation, your nurses and doctors will ask you about your pain because they want you to be comfortable, but also because they want to know if something is wrong. Be sure to tell your doctors and nurses when you have pain.

Purpose of this Booklet
This booklet talks about pain relief after surgery. It explains the goals of pain control and the types of treatment you may receive. It also shows you how to work with your doctors and nurses to get the best pain control.
Reading the booklet should help you:
- Learn why pain control is important for your recovery as well as your comfort.
- Play an active role in choosing among options for treating your pain.
Treatment Goals
People used to think that severe pain after surgery was something they "just had to put up with." But with current treatments, that's no longer true. Today, you can work with your nurses and doctors before and after surgery to prevent or relieve pain.
Pain control can help you:
- Enjoy greater comfort while you heal.
- Get well faster. With less pain, you can start walking, do your breathing exercises, and get your strength back more quickly. You may even leave the hospital sooner.
- Improve your results. People whose pain is well-controlled seem to do better after surgery. They may avoid some problems (such as pneumonia and blood clots) that affect others.
Pain control: What are the options?
Both drug and non-drug treatments can be successful in helping to prevent and control pain. The most common methods of pain control are described below. You and your doctors and nurses will decide which ones are right for you. Many people combine two or more methods to get greater relief.
Don't worry about getting "hooked" on pain medicines. Studies show that this is very rare--unless you already have a problem with drug abuse.
Pain Control Methods You May Be Using
To get the best results, work with your doctors and nurses to choose the methods that will work best for you.
Your nurses and doctors want to make your surgery as pain free as they can. But you are the key to getting the best pain relief because pain is personal. The amount or type of pain you feel may not be the same as others feel--even those who have had the same operation.
Before surgery
Drug treatment:
Take pain medicine.
Non-drug treatment:
Understand what operation the doctor is doing, why it is being done, and how it will be done. Learn how to do deep breathing and relaxation exercises (see example on pages 6 and 7).
During surgery
Drug treatment:
Receive general anesthesia, spinal anesthesia, or nerve blocks, or take a pain medicine through a small tube in your back (called an epidural).
After surgery
Drug treatment:
Take a pain medicine as a pill, shot, or suppository, or through a tube in your vein or back.
Non-drug treatment:
Use massage, hot or cold packs, relaxation, music or other pastimes to distract you, positive thinking, or nerve stimulation (TENS).
What can you do to help keep your pain under control? These seven steps can help you help yourself.
Before surgery
1. Ask the doctor or nurse what to expect.
- Will there be much pain after surgery?
- Where will it occur?
- How long is it likely to last?
Being prepared helps put you in control. You may want to write down your questions before you meet with your doctor or nurse.
2. Discuss the pain control options on pages 2 and 3 of this booklet with your doctors and nurses.
Be sure to:
- Talk with your nurses and doctors about pain control methods that have worked well or not so well for you before.
- Talk with your nurses and doctors about any concerns you may have about pain medicine.
- Tell your doctors and nurses about any allergies to medicines you may have.
- Ask about side effects that may occur with treatment.
- Talk with your doctors and nurses about, the medicines you take for other health problems. The doctors and nurses need to know, because mixing some drugs with some pain medicines can cause problems.
3. Talk about the schedule for pain medicines in the hospital.
Some people get pain medicines in the hospital only when they call the nurse to ask for them. Sometimes there are delays, and the pain gets worse while they wait.
Today, two other ways to schedule pain medicines seem to give better results.
- Giving the pain pills or shots at set times. Instead of waiting until pain breaks through, you receive medicine at set times during the day to keep the pain under control.
- Patient controlled analgesia (PCA) may be available in your hospital. With PCA, you control when you get pain medicine. When you begin to feel pain, you press a button to inject the medicine through the intravenous (IV) tube in your vein.
For both ways, your nurses and doctors will ask you how the pain medicine is working and change the medicine, its dose, or its timing if you are still having pain.
4. Work with your doctors and nurses to make a pain control plan.
You can use the form on pages 12 and 13 to begin planning for pain control with your nurses and doctors. They need your help to design the best plan for you. When your pain control plan is complete, use the form to write down what will happen. Refer to it after your operation. Then keep it as a record if you need surgery in the future.
After surgery
5. Take (or ask for) pain relief drugs when pain first begins
- Take action as soon as the pain starts.
- If you know your pain will worsen when you start walking or doing breathing exercises, take pain medicine first. It's harder to ease pain once it has taken hold. This is a key step in proper pain control.
6. Help the doctors and nurses "measure" your pain.
- They may ask you to rate your pain on a scale of 0 to 10. Or you may choose a word from a list that best describes the pain.
- You may also set a pain control goal (such as having no pain that's worse than 2 on the scale).
- Reporting your pain as a number helps the doctors and nurses know how well your treatment is working and whether to make any changes.
- They may ask you to use a "pain scale" like the one shown on page 7.
7. Tell the doctor or nurse about any pain that won't go away.
- Don't worry about being a "bother."
- Pain can be a sign of problems with your operation.
- The nurses and doctors want and need to know about it.
Stick with your pain control plan if it's working. Your doctors and nurses can change the plan if your pain is not under control. You need to tell the nurses and doctors about your pain and how the pain control plan is working.

Benefits and Risks of Pain Treatment Methods [Section not in Published Version]
This information is provided to help you discuss your options with your doctors and nurses. Sometimes it is best to combine two or more of these treatments or change the treatments slightly to meet your individual needs. Your doctors and nurses will discuss this with you.
Pain Relief Medicines
Nonsteroidal anti-inflammatory drugs:
Acetaminophen (for example, Tylenol), aspirin, ibuprofen (for example, Motrin), and other NSAIDs reduce swelling and soreness and relieve mild to moderate pain.
Benefits:
There is no risk of addiction to these medicines. Depending on how much pain you have, these medicines can lessen or eliminate the need for stronger medicines (for example, morphine or another opioid).
Risks:
Most NSAIDs interfere with blood clotting. They may cause nausea, stomach bleeding, or kidney problems. For severe pain, an opioid usually must be added.
Opioids:
Morphine, codeine, and other opioids are most often used for acute pain, such as short-term pain after surgery.
Benefits:
These medicines are effective for severe pain, and they do not cause bleeding in the stomach or elsewhere. It is rare for a patient to become addicted as a result of taking opioids for postoperative pain.
Risks:
Opioids may cause drowsiness, nausea, constipation,
Local anesthetics:
These drugs (for example, bupivacaine) are given, either near the incision or through a small tube in your back, to block the nerves that transmit pain signals.
Benefits:
Local anesthetics are effective for severe pain. Injections at the incision site block pain from that site. There is little or no risk of drowsiness, constipation, or breathing problems. Local anesthetics reduce the need for opioid use.
Risks:
Repeated injections are needed to maintain pain relief. An overdose of local anesthetic can have serious consequences. Average doses may cause some patients to have weakness in their legs or dizziness.
Methods Used to Give Pain Relief Medicines
Tablet or liquid:
Medicines given by mouth (for example, aspirin, ibuprofen, or opioid medications such as codeine).
Benefits:
Tablets and liquids cause less discomfort than injections into muscle or skin, but they can work just as well. They are inexpensive, simple to give, and easy to use at home.
Risks:
These medicines cannot be used if nothing can be taken by mouth or if you are nauseated or vomiting; sometimes these medicines can be given rectally (suppository form). There may be a delay in pain relief, since you must ask for the medicine and wait for it to be brought to you; also, these medicines take time to wear off.
Injections into skin or muscle
Benefits:
Medicine given by injection into skin or muscle is effective even if you are nauseated or vomiting; such injections are simple to give.
Risks:
The injection site is usually painful for a short time. Medicines given by injection are more expensive than tablets or liquids and take time to wear off. Pain relief may be delayed while you ask the nurse for medicine and wait for the shot to be drawn up and given.
Injections into vein:
Pain relief medicines are injected into a vein through a small tube, called an intravenous (IV) catheter. The tip of the tube stays in the vein.
Benefits:
Medicines given by injection into a vein are fully absorbed and act quickly. This method is well suited for relief of brief episodes of pain. When a patient controlled analgesia (PCA) pump is used, you can control your own doses of pain medicine.
Risks:
A small tube must be inserted in a vein. If PCA is used, there are extra costs for pumps, supplies, and staff training. You must want to use the pump and learn how and when to give yourself doses of medicine.
Injections into spine:
Medicine is given through a small tube in your back (called an epidural or intrathecal catheter).
Benefits:
This method works well when you have chest surgery or an operation on the lower parts of your body.
Risks:
Staff must be specially trained to place a small tube in the back and to watch for problems that can appear hours after pain medicine is given. Extra cost is involved for staff time and training and to purchase pumps and supplies.
Non-drug Pain Relief Methods
These methods can be effective for mild to moderate pain and to boost the pain-relief effects of drugs. There are no side effects. These techniques are best learned before surgery.
Patient teaching:
Learning about the operation and the pain expected afterwards (for example, when coughing or getting out of bed or a chair).
Benefits:
These techniques can reduce anxiety; they are simple to learn, and no equipment is needed.
Risks:
There are no risks; however, patient attention and cooperation with staff are required.
Relaxation:
Simple techniques, such as abdominal breathing and jaw relaxation, can help to increase your comfort after surgery.
Benefits:
Relaxation techniques are easy to learn, and they can help to reduce anxiety. After instruction, you can use relaxation at any time. No equipment is needed.
Risks:
There are no risks, but you will need instruction from your nurse or doctor.
Physical agents:
Cold packs, massage, rest, and TENS therapy are some of the non-drug pain relief methods that might be used following surgery.
Benefits:
In general, physical agents are safe and have no side effects. TENS, which stands for transcutaneous electrical nerve stimulation, is often helpful; it is quick to act and can be controlled by the patient.
Risks:
There are no risks related to the use of physical techniques for managing pain. If TENS is used, there is some cost and staff time involved for purchasing the machine and instructing patients in its use. Also, there is only limited evidence to support the effectiveness of TENS for pain relief in certain situations.
