My surgeon prescribed a different extended release opiate pain med less than 2 months ago. It seemed to work well for the first few weeks. I am still on a rapid release opiate since my surgery in late October. I'm still in a lot of pain and need additional surgery after my vertabreas heal. Is it the rapid release I'm building up a tolerance to (since I've been on it longer) or the newer extended release? If it were you, which med would you ask your doctor to increase? Or change all the meds to different ones?
