Like the parts of a machine, the joints in your body can break down when used too much or improperly. Repetitive motions such as throwing a ball with the same arm, or performing the same task with your hands for extended periods can cause the joint to wear down. When joints wear down or move out of place, they can rub against bone and create friction. This can lead to conditions such as bursitis (ber-SIGH-tus) and joint inflammation. Ligaments may also become stretched, especially if you're using a joint that's been partially dislocated, and cause pain and a clicking sound when you move the joint. Overuse of joints can also put unnatural pressure on nerves and cause pinched nerves and carpal tunnel syndrome. A chiropractor can help you successfully treat overuse injuries, which, when caught early, may only need rest and immobilization with a brace. Overuse injuries may also be treated with chiropractic adjustments to the joint, especially if overuse has caused a partial dislocation. It's important that overuse injuries are treated early, because they can lead to serious nerve damage, joint damage, and even disabilities. In some cases, you may need surgery to repair your overuse injury, such as stretched ligaments, chronic bursitis, pinched nerves, and carpal tunnel syndrome.
