yikes, I'm so sorry to hear about your crash. That's awful. Glad it wasn't worse.

As for pain management, take what you need to within the parametres of what the doc said was OK. Don't let your pain get out of control. You're much better off in the long run if you keep your pain down now. You'll get off the pain killers sooner and you'll be less likely to suffer from chronic pain. As for T3s, they are considered non-addictive. They do not cause physiological addiction tho some people claim that they cause psychological addiction. Another reason to make sure you take them at a frequency that keeps the pain down. You won't get that psych reinforcement of being in unmanageable pain and relieving it suddenly with meds, and cycling through that pattern.
If you are having to take a lot pain meds. Get off the T3s and ask the Doc to put you on straight codiene. T3s have acetaminophen in them which is toxic if taken excessively. Straight codiene is actually easier on your organ systems.
Take care.
