Are there any long term meds that can manage the pain of a pars defect? dont want to be addicted to opiods but wondering about other types.

Avoid narcotics: You're right. Narcotics for chronic non-cancer pain should be avoided. They cause more problems than they solve. Alternatives for chronic pain include tricyclic antidepressants like nortriptyline, anticonvulsants like gabapentin, and antiinflammatories like meloxicam. More important than meds are massage, relaxation, and other adaptive techniques. Learning to adapt is key. Good luck!
