Exercise relieves joint pain and stiffness. But you have to do it regularly. Like most treatments, if you don’t stick with exercise, the benefits go away.
If you’re overweight, slimming down will make a big difference in your OA. Losing at least 10% of your body weight (20 pounds in a 200-pound person) can cut your pain in half.
Walking aids, such as canes, and knee braces also help, especially if your knee is out of alignment. Splints can help with OA of the thumb. Ask your doctor or physical therapist about any other devices that may help.
