I’m going in soon for a morph pain pump trial implant. The pump is my only option because a SCS couldn’t be installed. Adhesions prevented correct wire lead position. My PM Doc said that once the pump is started then I will be taken off all my oral meds, immediately. He told me it is usually a ‘one for one’ trade. In other words I won’t have any drug ‘with-drawl’ symptoms. Is that true? Has anyone had drug with-drawls when switching to a morphine pump? What other side affects has anybody suffered? Any help will be greatly appreciated.
