I had a banded plication turned into a gastric sleeve. Since then I've been experiencing at times spasm and pain in my back on my left side. I had imaging, spinal fusion and some epidural injections but nothing seems to really get rid of this pain. Was wondering if anyone has ever heard or experienced this and what can be done about this.

I can't imagine how this would be related to your sleeve surgery. That operation doesn't go anywhere near your spine. You can have temporary backaches post op from laying on that damned metal table, or from your muscles bracing in front to protect your abdomen, but those should ease as you heal and stop bracing.

I suppose theoretically you could have some sort of nerve injury in that area from repeated surgeries, like scar tissue and adhesions, but I would think that pain would be felt in the stomach area or abdomen where they go in laparoscopically. A physical therapist can help manually massage out some of these areas if they can feel them.

Sometimes in rare instances a person can get referred pain from another area, but I would hope that they'd have considered that before doing spinal surgery! Sorry you are still in such pain after so many treatments!
