The neurologist came back with an initial diagnosis of a vertebral protrusion in his spine on two vertebrae. They are looking over the CT scans again but say they can not operate as it very likely would not get him to regain use of his legs. He has some movement but mostly pain response and I don't see how aleviating the pressure would not allow for regaining of motor function. It's been less than 3 weeks since the lameness was severe. In people, they do conservative treatment of anti-inflam meds and if that doesn't work, they move onto surgury. I can understand given the size of the spine of a ferret but is spinal damage caused by protrusion permanent? His blood glucose tends to remain steady at around 70 which is borderline and he was on insulinoma meds for 4 months but his level never wavered even when on or off and whether fasting or not, it kept reading around 70 so they took him off and he never once before or after ever had an episode. Thanks to all who helped or can help. [Posted in FML 6723]
