I am looking for a pain doctor. I am in severe pain and used to be on the 100mcg fentanyl patch along with oxycodone 15mg for breakthrough pain. The last doctor changed it to 30 mg ER morphine along with the 15 mg oxycodone. It isn t working well at all. I had a gastric bypass and I wonder if the extended release morphine leaves the stomach before it can be broken down and released. I was born with spina bifida and have lots of pain where the scar is from the closure site and I also have a tethered spinal cord which the doctors say I can t have it released because it would leave me paralyzed. It leaves me with only being able to try to manage the pain. can you online doctors prescribe fentanyl patches.
