Hi, I Have Degenerative Disc Disease Throughout My Spine And

Hi, I have degenerative disc disease throughout my spine and 4 herniated discs. Also several bone spurs with nerve impingement and I'm on 2 morphine ER 60 milligram twice daily and 2 Percocet for breakthrough pain. I'm in a steady 9 on the pain scale daily. The morphibe has never worked. I feel excruciating pain in my lower back, and the right side of my buttocks. I want to know what my DR can replace the morhine ER with and what can help give me a half normal life back. I'm a single mom. Please help. I'm hurting bad 24/7 Thank you in advance.
