Osteoarthritis

WHAT YOU SHOULD KNOW

Osteoarthritis, a form of arthritis or degenerative joint disease, occurs when the cartilage that normally cushions a joint becomes soft and breaks down. A bone ""spur'' (a pointed growth) that causes swelling and redness around the tissue may develop. The problem is most common in the fingers, feet, knees, hips, and the back and neck regions of the spine. It usually affects those over 50 years of age. The changes in the joints are long-term.

Causes

The exact cause of osteoarthritis is unknown.

Signs/Symptoms

The hallmarks of this disease are joint stiffness and pain. Joints may also swell. Cold and damp weather may make the aching worse. You may have trouble moving the affected joints; and when you do move them, you may hear a cracking sound. Usually, there is no fever, redness, or heat in the joints.

Care

Heat and medicine can help relieve the pain.

WHAT YOU SHOULD DO

  • Applying heat to the affected area may ease the pain. Put a warm heating pad or warm, moist towels on the painful joint, or soak it in a whirlpool bath for 10 to 20 minutes every hour for 48 hours.
  • Massaging the muscles around the joint also may relieve pain and stiffness, although massaging the joint itself is not helpful.
  • If your back is affected:
    • You may be more comfortable at night if you sleep on a firm mattress or place a piece of 3/4-inch plywood between your mattress and the box springs.
    • Sleeping on a waterbed is helpful for some people.
  • If your neck is affected and you have pain in your arms:
    • Wearing a soft neck collar may help relieve the pain.
    • If this is not helpful, ask your doctor if you can buy or rent a neck traction device to use at home.
  • Activity:
    • Rest is important when the joint becomes very painful.
    • Resume normal activity when you feel better.
    • Regular exercise will strengthen your muscles and reduce your symptoms.
    • Cold may increase the pain in the affected joint. You may want to wear thermal underwear or avoid outdoor activity during cold weather.
  • If you are overweight, it is important to lose weight.
  • You may use over-the-counter medicines such as deep-heating ointments or lotions to relieve pain.

Call Your Doctor If...

  • You have any problems that may be related to the medicine you are taking.

Seek Care Immediately If...

  • You develop chills, fever, or redness and tenderness of the affected joint.
