Arthritis Pain The word arthritis literally means joint inflammation, but is often used to refer to a group of more than 100 rheumatic diseases that can cause pain, stiffness, and swelling in the joints. These diseases may affect not only the joints but also other parts of the body, including important supporting structures such as muscles, bones, tendons, and ligaments, as well as some internal organs. 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. Chronic pain, such as that seen in people with osteoarthritis and rheumatoid arthritis, ranges from mild to severe and can last a lifetime. Chronic pain is a major health problem in the United States and is one of the most weakening effects of arthritis. More than 40 million Americans suffer from some form of arthritis, and many have chronic pain that limits daily activity. Osteoarthritis is by far the most common form of arthritis, affecting about 16 million Americans, while rheumatoid arthritis, which affects about 2.1 million Americans, is the most crippling form of the disease. Pain Is Personal Pain is a private, unique experience that cannot be seen. 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. The most common way to measure pain is for the doctor to ask you, the patient, about your problems. For example, the doctor may ask you to describe the level of pain you feel on a scale of 1 to 10. You may use words like aching, burning, stinging, or throbbing. These words will give the doctor a clearer picture of the pain you are experiencing. There is no single treatment that applies to all people with arthritis, but rather the doctor will develop a management plan designed to minimize your specific pain and improve the function of your joints. 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 very familiar with the problems of the disease. Acupuncture. This procedure should only be done by a licensed acupuncture therapist. In acupuncture, thin needles are inserted at specific points in the body. Scientists think that this stimulates the release of natural, pain-relieving chemicals produced by the brain or the nervous system. 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 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. Disease-modifying anti-rheumatic drugs (DMARDS). These are drugs used to treat people with rheumatoid arthritis who have not responded to NSAIDs. Some of these include 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. 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 only be done once or twice a year. 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 Arthritis and Musculoskeletal and Skin Diseases Information Clearinghouse has a separate fact sheet on arthritis and exercise. See the end of this fact sheet for contact information.) 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. Total joint replacement has provided not only dramatic relief from pain but also improvement in motion for many people with arthritis. Coping With Arthritis Pain The long-term goal of pain management is to help you cope with a chronic, often disabling disease. You may be caught in a cycle of pain, depression, and stress. To break out of this cycle, you need to be an active participant with the doctor and other health care professionals in managing your pain. This may include physical therapy, cognitive-behavioral therapy, occupational therapy, biofeedback, relaxation techniques (for example, deep breathing and meditation), and family counseling therapy. Another technique is to substitute distraction for pain. Focus your attention on things that you enjoy. Imagine a peaceful setting and wonderful physical sensations. Thinking about something that is enjoyable can help you relax and become less stressed. Find something that will make you laugh–a cartoon, a funny movie, or even a new joke. Try to put some joy back into your life. Even a small change in your mental image may break the pain cycle and provide relief. Richard T Herrick,MD herrickclinic@mindspring.com www.herrickclinic.com
