Most forms of arthritis are associated with pain that can be divided into two general categories: acute and chronic. Acute pain is temporary. It can last a few seconds or longer but wanes as healing occurs. Some examples of things that cause acute pain include burns, cuts, and fractures. Chronic pain, such as that seen in people with osteoarthritis and rheumatoid arthritis, ranges from mild to severe and can last weeks, months, and years to a lifetime.

The pain of arthritis varies greatly from person to person, for reasons that doctors do not yet understand completely. Factors that contribute to the pain include swelling within the joint, the amount of heat or redness present, or damage that has occurred within the joint. In addition, activities affect pain differently so that some patients note pain in their joints after first getting out of bed in the morning, whereas others develop pain after prolonged use of the joint. Each individual has a different threshold and tolerance for pain, often affected by both physical and emotional factors. These can include depression, anxiety, and even hypersensitivity at the affected sites due to inflammation and tissue injury. This increased sensitivity appears to affect the amount of pain perceived by the individual. Social support networks can make an important contribution to pain management.

Since doctors rely on your description of pain to help guide treatment, you may want to keep a pain diary to record your pain sensations. You can begin a week or two before your visit to the doctor. On a daily basis, you can describe the situations that cause or alter the intensity of your pain, the sensations and severity of your pain, and your reactions to the pain. For example: "On Monday night, sharp pains in my knees produced by housework interfered with my sleep; on Tuesday morning, because of the pain, I had a hard time getting out bed. However, I coped with the pain by taking my medication and applying ice to my knees." The diary will give the doctor some insight into your pain and may play a critical role in the management of your disease.

• Take your medical history and ask questions such as, How long have you been experiencing pain? How intense is the pain? How often does it occur? What causes it to get worse? What causes it to get better?
  
  
• Review the medications you are using
  
  
• Conduct a physical examination to determine causes of pain and how this pain is affecting your ability to function
  
  
• Take blood and/or urine samples and request necessary laboratory work
  
  
• Ask you to get x rays taken or undergo other imaging procedures such as a CAT scan (computerized axial tomography) or MRI (magnetic resonance imaging) to see how much joint damage has been done.
  
  

Once the doctor has done these things and reviewed the results of any tests or procedures, he or she will discuss the findings with you and design a comprehensive management approach for the pain caused by your osteoarthritis or rheumatoid arthritis.

Short-Term Relief

• Medications--Because people with osteoarthritis have very little inflammation, pain relievers such as acetaminophen (Tylenol*) may be effective. Patients with rheumatoid arthritis generally have pain caused by inflammation and often benefit from aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (Motrin or Advil).
  
  
• Heat and cold--The decision to use either heat or cold for arthritis pain depends on the type of arthritis and should be discussed with your doctor or physical therapist. Moist heat, such as a warm bath or shower, or dry heat, such as a heating pad, placed on the painful area of the joint for about 15 minutes may relieve the pain. An ice pack (or a bag of frozen vegetables) wrapped in a towel and placed on the sore area for about 15 minutes may help to reduce swelling and stop the pain. If you have poor circulation, do not use cold packs.
  
  
• Joint protection--Using a splint or a brace to allow joints to rest and protect them from injury can be helpful. Your physician or physical therapist can make recommendations.
  
  
• Transcutaneous electrical nerve stimulation (TENS)--A small TENS device that directs mild electric pulses to nerve endings that lie beneath the skin in the painful area may relieve some arthritis pain. TENS seems to work by blocking pain messages to the brain and by modifying pain perception.
  
  
• Massage--In this pain-relief approach, a massage therapist will lightly stroke and/or knead the painful muscle. This may increase blood flow and bring warmth to a stressed area. However, arthritis-stressed joints are very sensitive, so the therapist must be familiar with the problems of the disease.
  
  

Osteoarthritis and rheumatoid arthritis are chronic diseases that may last a lifetime. Learning how to manage your pain over the long term is an important factor in controlling the disease and maintaining a good quality of life. Following are some sources of long-term pain relief.

Long-Term Relief

• Medications
  

  Biological response modifiers--These new drugs used for the treatment of rheumatoid arthritis reduce inflammation in the joints by blocking the reaction of a substance called tumor necrosis factor, an immune system protein involved in immune system response. These drugs include Enbrel and Remicade.

  Nonsteroidal anti-inflammatory drugs (NSAIDs)--These are a class of drugs including aspirin and ibuprofen that are used to reduce pain and inflammation and may be used for both short-term and long-term relief in people with osteoarthritis and rheumatoid arthritis. NSAIDs also include Celebrex, one of the so-called COX-2 inhibitors that block an enzyme known to cause an inflammatory response.

  Disease-modifying antirheumatic drugs (DMARDs)--These are drugs used to treat people with rheumatoid arthritis who have not responded to NSAIDs. Some of these include the new drug Arava and methotrexate, hydroxychloroquine, penicillamine, and gold injections. These drugs are thought to influence and correct abnormalities of the immune system responsible for a disease like rheumatoid arthritis. Treatment with these medications requires careful monitoring by the physician to avoid side effects.

  Corticosteroids--These are hormones that are very effective in treating arthritis but cause many side effects. Corticosteroids can be taken by mouth or given by injection. Prednisone is the corticosteroid most often given by mouth to reduce the inflammation of rheumatoid arthritis. In both rheumatoid arthritis and osteoarthritis, the doctor also may inject a corticosteroid into the affected joint to stop pain. Because frequent injections may cause damage to the cartilage, they should be done only once or twice a year.

  Other products--Hyaluronic acid products like Hyalgan and Synvisc mimic a naturally occurring body substance that lubricates the knee joint and permits flexible joint movement without pain. A blood-filtering device called the Prosorba Column is used in some health care facilities for filtering out harmful antibodies in people with severe rheumatoid arthritis.

• Weight reduction--Excess pounds put extra stress on weight-bearing joints such as the knees or hips. Studies have shown that overweight women who lost an average of 11 pounds substantially reduced the development of osteoarthritis in their knees. In addition, if osteoarthritis has already affected one knee, weight reduction will reduce the chance of it occurring in the other knee.
  
  
• Exercise--Swimming, walking, low-impact aerobic exercise, and range-of-motion exercises may reduce joint pain and stiffness. In addition, stretching exercises are helpful. A physical therapist can help plan an exercise program that will give you the most benefit.*
  
  

  * The National Institute of Arthritis and Musculoskeletal and Skin Diseases Information Clearinghouse has a separate booklet on arthritis and exercise.

• Surgery--In select patients with arthritis, surgery may be necessary. The surgeon may perform an operation to remove the synovium (synovectomy), realign the joint (osteotomy), or in advanced cases replace the damaged joint with an artificial one (arthroplasty). Total joint replacement has provided not only dramatic relief from pain but also improvement in motion for many people with arthritis.
  
  

Some alternative or complementary approaches may help you to cope with or reduce some of the stress of living with a chronic illness. It is important to inform your doctor if you are using alternative therapies. If the doctor feels the approach has value and will not harm you, it can be incorporated into your treatment plan. However, it is important not to neglect your regular health care or treatment of serious symptoms.

The Multipurpose Arthritis and Musculoskeletal Diseases Center at Stanford University, supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), has developed an Arthritis Self-Help Course that teaches people with arthritis how to take a more active part in their arthritis care. The Arthritis Self-Help Course is taught by the Arthritis Foundation and consists of a 12- to 15-hour program that includes lectures on osteoarthritis and rheumatoid arthritis, exercise, pain management, nutrition, medication, doctor-patient relationships, and nontraditional treatment.

You may want to contact some of the organizations listed at the end for additional information on the Arthritis Self-Help Course and on coping with pain, as well as for information on support groups in your area.

At the Specialized Center of Research in Osteoarthritis at Rush-Presbyterian-St. Luke's Medical Center in Chicago, Illinois, researchers are studying the human knee and analyzing how injury in one joint may affect other joints. In addition, they are analyzing the effect of pain and analgesics on gait (walking) and comparing pain and gait before and after surgical treatment for knee osteoarthritis.

At the University of Maryland Pain Center in Baltimore, NIAMS researchers are evaluating the use of acupuncture on patients with osteoarthritis of the knee. Preliminary findings suggest that traditional Chinese acupuncture is both safe and effective as an additional therapy for osteoarthritis, and it significantly reduces pain and improves physical function.

At Duke University in Durham, North Carolina, NIAMS researchers have developed cognitive-behavioral therapy (CBT) involving both patients and their spouses. The goal of CBT for arthritis pain is to help patients cope more effectively with the long-term demands of a chronic and potentially disabling disease. Researchers are studying whether aerobic fitness, coping abilities, and spousal responses to pain behaviors diminish the patient's pain and disability.

NIAMS-supported research on arthritis pain also includes projects in the Institute's Multipurpose Arthritis and Musculoskeletal Diseases Centers. At the University of California at San Francisco, researchers are studying stress factors, including pain, that are associated with rheumatoid arthritis. Findings from this study will be used to develop patient education programs that will improve a person's ability to deal with rheumatoid arthritis and enhance quality of life. At the Indiana University School of Medicine in Indianapolis, health care professionals are looking at the causes of pain and joint disability in patients with osteoarthritis. The goal of the project is to improve doctor-patient communication about pain management and increase patient satisfaction.

The list of pain studies continues. A NIAMS-funded project at Stanford University in California is evaluating the effects of a patient education program that uses a book and videotape to control chronic pain. At Indiana University in Indianapolis, Institute-supported scientists are determining whether strength training can diminish the risk of severe pain from knee osteoarthritis. And a multicenter study funded by the National Center for Complementary and Alternative Medicine and NIAMS, and coordinated by the University of Utah School of Medicine, is investigating the effects of the dietary supplements glucosamine and chondroitin sulfate for knee osteoarthritis.
