I recently underwent spinal fusion surgery. T3-8, broke 3 ribs and collapsed a lung. Got into pain management clinic and they perscribed me as follows: 40 mg oxycodone (percocet), and 50mg of methadone per day. I am 5 wks out of surgery and still have a lot of constant pain. I am concerned with methadone as i have researched it and discovered the severity of withrawls and detox. Does anyone have any info that could help me? I am trying to get a second opinion for my own comfort, but would greatly appreciate any info anyone may share with me. Thank you.
