I had this problem last year and it was pretty scary...but mine ended up being the result of seratonin syndrome from the meds. The halluncinations stopped after I got off all my meds. None of the meds individually would have caused hallucinations but that seratonin syndrome was nasty business. I always knew that the hallucinations were not real at the time. For me, at least, the hallucinations were not caused by my RSD but a complication caused by the meds. I'm sorry you are going through this...I know how upsetting it can be.
