I am having an RFL lumbar left side only tomorrow. I had this done previously in 2008 and was already taking Hydrocodone 10 mg. The discarge summary came with a script at that time for Percocet also. Doc said "take both, you'll need it. I already know the horrible pain I am going to have post op until the nerves actually die. I guess in about 5 days. They are going to have a prescription for me on discharge for dilaudid. I don't know anything about this drug only that I was given this IV once in an ER visit. I am terrified about taking this and know I will need it. Darn docs could have done this bilaterally tomorrow because both hips and legs are affected but you know contracts and reimbursement and I really do as my former professional was medical collections, reimbursement, etc. So the 2nd one is scheduled for 11/18/13. Question: Should I continue my percocet 10's along with the dilaudid tomorrow or what? I am terrified of this medication but know I'm going to need it.
