I am a post polio patient currently in need of rotator cuff repair (2 tendons conpletely detached with massive tears) I am already a chronic pain patient (post polio pain, DDD,autoimmune disease) and polio patients are believed to have at least twice the pain issues as non-polios following surgery (due to previous damage to the brain stem and spinal areas) I am very afraid my pain cannot be controlled after surgery. My surgeon does outpatient surgery for this procedure. What meds might be able to handle this challenge?
