Hello. My Name Is Kayla. In 2006 I Fell 2

Hello. My name is Kayla. In 2006 I fell 2 1/2 stories. I broke my back, my sacral bone, pelvic bone, ribs, rt elbow and shattered left knee. They didn't catch the pelvic or sacral or back until about a year later. But by then my pelvic bone displaced 2 inches. Never healed together. I have been on meds since then. I am now on flexeral,Lyrica, oxycodone with aced. My doctor is great but thinks I will be on meds for the rest of my life. But the meds doesn't seem to help me like they use too. What is the next step for me with meds?
