My son's physician wants him to come off of all narcotics (he's on saboxone) for 8 weeks before his upcoming surgery. I don't really understand this reasoning. He does have problems with addiction, thus the saboxone, but it is going to be so hard for him to completely come off of all pain medication that long before the surgery. Has anyone else experienced this? I understand wanting the pain medication to work better post surgery, but 8 weeks of suffering?? Thanks for any comments. He is 24 and looking to have spinal fusion L3 - S1 in June.
