Hi Star,
I read your question and almost fell out of my chair! 17 years ago I was given a shot for pain in the emergency room that ended my life as I knew it. The pain medication I received was Demerol, and right after that shot I became very ill and developed severe anxiety and neurological type symptoms. I just posted my story on this web site 2 days ago. If you're interested, go here to read it: (it's really long, sorry)

Since then I have only gotten worse. I have searched for answers for over 17 years now and still can't get help! I have seen countless doctor's and Psychiatrists all of whom tell me the pain shot could not have caused this to happen to me. All I know is that before I got that shot I was not suffering from neurological problems or severe, never-ending anxiety. I had a mild form of OCD since childhood that didn't interfere with living. After that medication I suddenly have a panic disorder, anxiety disorder, severe depresssion, possible Bi-polar and my OCD kicked into overdrive. I believe the medication is to blame, and I totally agree with what Paxiled told you. Dr. Gould's response is exactly what I would expect and have heard many times my own self. I asked another doctor in another forum about the ability of drugs/medications causing these issues and received no answer. He copied and pasted the side effects from Demerol injections. lol I know the side effects, but why are they permanent in my body????
I have contacted people in the mental health world and have gotten bits of info here and there, (damaging effects on the nuerotransmitters in the brain) but not enough to solve this! But I am actively trying and have an appt with a Neurologist next month that I am hoping will yield some answers. If you don't mind, I'd like to add you as a friend. That way I can pass along anything that can possibly help you out.
Just know you're not alone and not crazy!
