I don't remember the entire process but I believe I saw a neuropsychologist or neuro psychiatrist as one of the first steps. No they did not make me stop taking medications prior to the trial. This all took place in 2016 before the opioid Hysteria grabbed a hold of the medical community. Yes doctor Park manages my oral medications which are minimal to say the least and our continued at least in my case as a perceived placebo. Whatever the process was I didn't find it overly evasive or too time consuming. You start by getting an appointment at the pain clinic, it might help to let them know you're not looking for a doctor to prescribe opioids that you're interested solely in the pain pump and or stimulator.
