There are a lot of other great sports that could probably bring plenty of excitement instead, as a substitute. Biking, hiking, jogging, mountain climbing, hang gliding, sailing, surfing, diving, hunting, flying. Maybe even racketball or tennis.
Me? I just want to be able to live a normal life. I'm willing to say goodbye to basketball, even though I'll always miss it.
Most of the sports you mention will require your core. You've said your condition is "debilitating," now you just can't play basketball? Which is it?
