That depends on what you mean by damage.
When you exercise with a high intensity, moving large weights, performing explosive movements, or fatiguing the muscles to near failure, your muscles are damaged. Creatine increase the activity of repair cells in the muscle, speeding up muscle repair. So creatine is helpful with the frequent damage done to muscles by exercising.
If you mean traumatic damage such as a torn muscle, the evidence is less clear. If I had to guess, I would say it probably helps a little. I don’t think much research has been done in this area.
Using creatine may increase your risk of injury if your not paying attention to your body. Creatine allows you to exercise with higher intensity, and higher intensity mean greater risk of injury. Use your head when working out. If something hurts, stop. Most minor aches or pains will be gone by the next time you workout, but watch out for the ones that keep recurring.
