Another thing to ask your pain management or integrative pain specialist to try is ketamine troches and oxytocin troches. They desolve under your tongue. They work together but you can also take them separately. I find that they work best together. You take the oxytocin and then wait 30 min. before taking the ketamine. Unfortunately, they don't work in pill form because the oxytocin cannot survive stomach acid. It's also an opioid alternative but is still a controlled substance. It is very effective and is actually the best pain relief I've had in many years! I am currently considering a ketamine infusion. Hope this might help someone!
