You could ask them about the potential to be prescribed a dissociative drug instead of an opioid. I have heard that they can be very helpful in regards to chronic pain.
Over the course of couple of years I went through all possible drugs the doctors could think of. Some worked but side effects outweighed the benefits. In terms of side effects Co-codamol (Codeine and paracetamol) was best but they didn't want to prescribe a version without paracetamol. Once consultant even suggested that I am making this up and I just want to get opiates and he won't fall for that. This was heartbreaking and since that point I have not asked for any treatment that relates to opiates. I have made a complaint against this consultant but the hospital dismissed it and didn't consider my appeal even though by law they must. I just have no strength to go through courts I have too much on my plate.
