A few months ago after a trip to the ER I was given Tramadol HCL 50mg for recovery. I started with one pill every four hours and soon I was taking only one every nine hours, I was completely off of it within the week with no withdrawal symptoms. It worked perfectly fine for pain relief but I had some pretty annoying side effects (anxiety, nausea, headaches, paranoia, uncontrollable muscle tightening, muscle tremors, and two short auditory hallucinations). I'm wondering if all (oral) opioids would likely cause these same side effects for me or if maybe some of them would be better. I need at least one surgery in the near future and I'd like to avoid being prescribed medicines that will give me these same side effects.
