I have my own issues w creatine and understand why many pro-sport locker-rooms ban it.
It builds the muscle, but not the connective tissue.
The result is torn tendons and 3 months to heal.
Wow... were you a power lifter? I used it for regular building of mass, but I also took Yoga, Tae Kwon Do, did regular calisthenics, and ran 10-15 miles a week. In over 5 years of using creatine, the worst problem I had was headaches from poor water consumption (waste removal).
If you don't take a whole-body approach to weight training, you will absolutely get hurt. I wasn't trying to bulk up for a competition or show, and I maintained a healthy regimen of heavy weight training combined with flexibility and cardiovascular exercise to maintain systemic health.
I know too many young guys who try to beef up into mega men only to be sidelined by massive injuries such as you describe. Best example: working show muscles (traps, pecs, abdominals, biceps, anterior and medial deltoid heads, quads) while ignoring their supporting and partnering muscles (lats, inguinals, glutes, triceps, posterior deltoid and rhomboid, hamstrings).
