A Suggested Pain Scale

I was just thinking about how I'd make a pain scale, and this is what I came up with:

1. Unaware of any pain
2. Not sure if pain is still present or subsided (like listening to a very soft sound, or seeing a shape disappear into a cloud)
3. Pain is confirmed, but "interesting" (like plucking a hair or pressing a bruise)
4. Steps are actively taken to avoid the pain (walking with a sprain)
5. Seeking ways to reduce the pain (headache)
6. Immediate help for pain is sought
7. Focusing all attention on reducing pain
8. Unable to help oneself in removing pain anymore
