You can't go back in time to "save yourself"... That's the thing.
You imagine the issue as if it was like this:
- You have an injury in 2012.
- Years go on, and time travel finally gets possible in 2025.
- You go back in time to the year 2012.
- You save yourself from getting injured.
The problem with this is that when you first experience 2012, if your 2025 self travelled back in time to get to that very 2012 you're currently in, he is there all along when you first experience it.
