Topic Overview

What is pain?

Pain is your body's way of warning you that something is wrong. If you step on a sharp object or put your hand on a hot stove, the pain lets you know right away that you are hurt and need to protect yourself. You may have pain from an injury, after surgery, or from a health problem like cancer, osteoarthritis, low back pain, headaches, or fibromyalgia.

Your body feels pain through nerves in your skin and organs. These nerve endings send pain signals to your brain.

What are the different types of pain?

Pain can affect:

• Muscles, bones, and joints. It also affects the ligaments and tendons. This pain can happen from injuries or muscle strain. Health problems like osteoarthritis, rheumatoid arthritis, and fibromyalgia also can cause it.
• Nerves and the nervous system. This type of pain happens because of pressure on nerves or damage to them from an injury or a health problem. Sometimes pain occurs when something goes wrong with the central nervous system. Diabetes, shingles, and sciatica are examples of health problems that cause nerve pain.
• Organs. Pain in your organs occurs because of injuries, infections, or health problems such as cancer, inflammatory bowel disease, irritable bowel syndrome, pelvic pain, and stomach ulcers.

You can have more than one kind of pain at the same time. For example, cancer can cause pain in your bones and your organs.

Does all pain feel the same?

Pain feels different for everyone. Something that doesn't bother one person might feel very bad to someone else.

Pain can feel sharp or dull. It may throb or burn. It may be in one part of your body, such as with a headache or a stomach ulcer. Or you may feel pain all over, like when your muscles ache from intense exercise or the flu.

Some pain may be so mild that you can ignore it until it goes away. But other pain may be so bad that you can't do your daily activities without medicine or other treatment.

How long can pain last?

Pain may last for a short time or a long time. It may come and go or it may be constant.

Pain that starts quickly and lasts for a short time is called acute pain. Examples include pain from an injury, a headache, childbirth, or right after surgery.

Pain that goes on for months or years is called chronic pain. You may have this pain from an injury that doesn't heal or from a health problem like low back pain, very bad headaches, or diabetic neuropathy.

Long-term pain that isn't controlled can take the joy from your life. You may not be able to work. Physical activity may be too painful or exhausting.

You may become depressed and anxious. Controlling pain can help with all these things.

Treatment

Many different treatments can ease pain. Medicines are the most common treatment. But to feel better, you also can try other things, such as reducing your stress level or changing how you think.

Your treatment depends on several things, including:

Knowing When Pain Is Worse

Pain can get worse slowly. So it can be hard to tell if your pain is getting worse, especially if you've had it for a while. But you can look for signs that your pain is worse. You may notice that:

• You have new pain. The pain may be in a new area, or it may feel different.
• Your pain treatment no longer works, or it doesn't work like it used to.
• Your medicine wears off too soon between each dose.
• Your pain gets in the way of daily activities such as eating and sleeping.

Using a pain scale and a pain diary can help you know how much pain you're having. These tools also can help you tell your doctor what your pain feels like so that he or she can help you. You can use these tools for short-term or long-term pain.

Use a pain scale

Health professionals often use a pain scale to find out how much pain a person has. The scale is from 0 to 10, with "0" being no pain and "10" being the worst possible pain.

To use a pain scale, write down how strong your pain is and when it comes and goes.

Use a pain diary

Use a pain diary(What is a PDF document?) to keep a record of your pain. Write down what pain medicines you're taking and how well they are working.

Also write down anything else you're doing to control your pain. Note the details of your pain so you can tell your doctor. Is it burning? Throbbing? Steady? How long does it last?

Take your diary and pain scale and any questions with you when you see your doctor. Talk to your doctor anytime you have new pain or your pain gets worse.

Side Effects of Pain Medicines

All medicines have side effects. But many side effects can be managed so that you can still take the medicine. Talk to your doctor if you have any side effects. Your doctor may change your dose or the type of medicine you take.

Examples of side effects of over-the-counter medicines

• Acetaminophen (Tylenol)

  This medicine may cause:

  • Nausea.
  • Rash.
  • Liver damage (with high doses).
• Nonsteroidal anti-inflammatory drugs (such as Advil, Motrin, and Aleve)

  These may cause:

  • Stomach upset, heartburn, and nausea. Taking the medicine with food may help prevent these problems.
  • Stomach ulcers and kidney problems (with long-term use).
  • Allergic reaction (rare).
  • Increased risk of heart attack and stroke. These risks are greater if the medicine is taken at higher doses or for longer than recommended.

  No one younger than 20 should take aspirin. It has been linked to Reye syndrome, a serious illness.

Examples of side effects of prescription medicines

• Anticonvulsant medicines

  These may cause:

  • Dizziness.
  • Drowsiness.
  • Fatigue.
  • Headache.
  • Confusion.
  • Skin rash.

• Corticosteroids

  These may cause:

  • Nausea and vomiting.
  • Swelling of hands and feet.
  • Increased appetite.
  • Increased risk of infection.
  • Osteoporosis (with long-term use).

  Because of the chance of side effects, doctors usually try to prescribe steroid medicines only for a short time.

• Opiate pain relievers

  These may cause:

  • Constipation.
  • Dizziness, lightheadedness, or feeling faint.
  • Drowsiness.
  • Nausea or vomiting.

If you take opiate pain relievers for longer than a week or so, they can cause your body to keep expecting the medicine. This is called drug dependency. This is not the same as addiction.

Addiction is a behavioral problem that happens when a person has a craving for the drug. This craving may not even be related to the level of pain. But opiate pain relievers rarely cause addiction when they are used under a doctor's care. Talk to your doctor if you are worried about addiction.

• Tricyclic and tetracyclic antidepressants

  These may cause:

  • Blurred vision.
  • Confusion.
  • Constipation.
  • Drowsiness and fatigue.
  • Dry mouth.
  • Loss of sexual desire or ability.

• Serotonin and norepinephrine reuptake inhibitor (SNRI) antidepressants

  These may cause:

  • Constipation.
  • Cough.
  • Dizziness.
  • Dry mouth.
  • Headache.
  • Nausea and loss of appetite.
  • Decrease in sexual desire or ability.
  • Sleep problems.
  • Weight loss.

• Selective serotonin reuptake inhibitor (SSRI) antidepressants

  These may cause:

  • Nausea.
  • Loss of appetite.
  • Diarrhea.
  • Anxiety.
  • Sleep problems.
  • Loss of sexual desire or ability.
  • Headaches.
  • Weight gain.

The U.S. Food and Drug Administration (FDA) has issued an advisory on antidepressant medicines and the risk of suicide. The FDA does not recommend that people stop using these medicines. Instead, a person taking antidepressants should be watched for warning signs of suicide. This is especially important at the beginning of treatment or when the doses are changed.

For more information, see the topic Dealing With Medicine Side Effects and Interactions.

Following a Treatment Plan

The best way to control your pain is to follow your treatment plan and give it time to work.

Some treatments may take a few days or weeks to improve your pain. You and your doctor can talk about how long you should stay on a medicine or other treatment.

It's very important to take your medicines exactly as your doctor prescribes. Following your doctor's advice will help you get the right amount of medicine with as few side effects as possible. It also will help you and your doctor know if a medicine is working for you.

Make sure to tell your doctor about any medicines or herbal supplements you take. Your other medicines and supplements could mix in a bad way with your pain medicines. This could keep the pain medicine from working as well as it could.

Don't wait for pain to get bad

Make the most of your pain medicines by following these rules:

• Take them on time (by the clock).
• Do not skip a dose or wait until you think you need it.
• Be prepared for breakthrough pain. You may find that taking your medicine works most of the time but that your pain flares up during extra activity or even for no clear reason. These flare-ups are called breakthrough pain. Your doctor can give you a prescription for fast-acting medicines that you can take for breakthrough pain.
• If you have more than one doctor, pick one doctor to be in charge of all your medicines. If more than one doctor prescribes pain medicine, make sure they talk to each other about it.

Learn more about:

• Taking medicines as prescribed.
• Working with more than one doctor.

When to Call Your Doctor

Only you can tell how much pain you have and whether it's getting better or worse. Talk to your doctor anytime you have new pain, your pain gets worse, or your treatment isn't controlling your pain.

Some people may think they're weak if they tell their doctor about their pain. Or they worry that they're bothering their doctor.

You're not weak. And you're not bothering the doctor. Your doctor wants to help you. But to help you, he or she needs to know how you really feel.

Call your doctor if:

• Your pain gets worse or is out of control.
• You have stomach pain, an upset stomach, constipation, or heartburn that lasts or comes back.
• You don't get better as expected.
• You cannot sleep because of pain.
• You are very worried or anxious or are feeling sad about your pain.
• Your pain medicine isn't working or you have trouble taking it.

Getting Support

Needing other people for emotional support is a normal part of life. You may have to lean on family and friends if you're getting over an injury or surgery or if you live with pain much of the time.

It can be hard sometimes to ask for help. But don't be afraid to reach out. Other people can help you—and they may be eager to help. Along with your family and friends, you can seek support from:

• Counseling. A professional counselor can help you cope with pain, stress, and things that happen in your life. Counseling can help you understand and deal with an illness.
• Your doctor. Find a doctor you trust and feel comfortable with. Be open and honest about your fears and concerns. Your doctor can help you get the right medical treatments, including counseling.
• Religious groups. Religious or spiritual groups may help you meet people and get involved in the community. Some religious groups can help you get counseling or other social support services.
• Social groups. You can meet new people and get involved in activities you enjoy.
• Community support groups. In a support group, you can talk to others who have dealt with the same problems you have. You can encourage each other and learn ways of coping with your feelings.
