Yes! It is actually very dangerous to change your own torsion springs. We do not recommend that you make this repair. The torsion spring holds tension that counterbalances the weight of your door. When that tension breaks, it can cause serious damage or fatal harm to you or those standing nearby. Even experienced technicians have been injured when replacing this part.
If your spring is broken, do not open or close your door. By trying to operate the door, you can damage the opener or door itself. Also, it puts you at risk of injury.
