Oh, I feel for you. I had lower spine misalignment that was crushing my spinal cord. Caused all kinds of problems that were fixed with the surgery. Before that though I was on fentanyl, and other opioids. I had such nausea that I loss weight and was constipated all the time. I was able to quit the narcotics after my surgery but I now suffer from gastrointestinal problems that I’m sure is from long term side effects of the medication. I know the meds gave me some relief but not enough, it took the surgery to do that.
