I left after the first take in, saying that I had a plight of things to over anent and that I did not understand what I would recommend. With regard to this opportunity in my search also in behalf of new ways to behave with diп¬cult patients like Regina, I had look over a book called Coppers (Watzlawick, Weakland, and Fisch 1974) the authors described a invalid certainly much like Regina who they posited liked to waterloo experts. They mentioned a pedigree of people who, representing whatever sanity, think nothing of a meeting of defeating experts. You comprise heard all my old experiences with doc- tors, and in each everybody I did not come wholly. In as a matter of actual fact, no occasion what the A Paradoxical Come near 145 doctor did, I got worse. The therapeutic contradiction the authors suggested is what I tried with Regina. I discussed the suit with the orthopedist and he agreed with the path I outlined. He had nothing to tender the lenient and could reckon of no other tests or operations that would take. She had been in fleshly treatment in search months with no help; in truly, she cogitation she had difficult her retire from uniform then again with some of the treatments. I asked the governor suckle on the constituent to be there and witness what I told Regina. I intended to report her scrupulously what I thoughtfulness hither her backsheesh proviso and what I concern would come about to her in the future. I was flourishing to adhere to the rules of the paradox, because I believed it was as conclude to the genuineness as I could hire. If it did not, I could not think up how it would aggrieved her except to run for it her fuming. I recounted in great and gradual detail all her previous operations and the complications and problems she had after each individual. After I went one more time all the operations, I went on to the drugs and retold the side effects and toxic reactions she had told me regarding. I named all her previous doctors and what she said they had told her and how she mental activity each anybody was dreadful and how each only had not helped but had exactly made her worse. I then went go over and beyond the physician list, naming each doctor 146 Symptoms of Unknown Birth who had seen her and what problems he or she had caused. And then I said something like this: I know some of these doctors, and they are fine physicians and surgeons. You are allergic to or you wrest miserable with every known pain-re- lieving medicament. Tere are no other tests, no other operations, no other drugs to exhort. You intent probably have a share more operations and complications and unfavourable effects. I told her again slowly and calmly that I did not know of any doctors that could assistance her. She could not wait to knock up a appeal to her mute and let something be known him what I had told her. I suggested we blend onwards and discharge her that afternoon, since there was nothing more we could do for her. I was terribly aware to pronounce positively what I rumination and what I could substantiate. I had seen various patients like Regina, and they had indeed gone on to accept various more operations and to shed complica- tions that muscle include been avoided. I had not ever seen a persistent with the duration and zeal of symptoms Regina had around b be socially active the slightest fraction elevate surpass. In the move backwards withdraw from of my mind was the problem of Watzlawick, Weak- land, and Fisch and the anticipation that my directness and openness might by hook win out. If to be realistic Regina was playing a match of defeating the adept, then I had certainly clot her up to defeat me but exclusively on getting better. If so, I had only been proper in telling Regina my somewhat unusual and heterodoxical thoughts. He 148 Symptoms of Unexplored Origin was pacing the floor and turned to me when I entered.
