Look thorugh fit buddy for your topic, many of these injuries have been answered in the past.
No offense.
Another thing in general - injuries can be hard to diagnose online because they really need to be evaluated physically, so see a doctor or at least a competent trainer if you think you have really damaged your self.
Good luck!
