        Diagnosis


        Diagnosing back pain in a horse is usually straightforward, but pinpointing the cause can be
        extremely  difficult.  Many  horses  are  very  stoical  and  will  put  up  with  considerable
        discomfort before exhibiting any signs. Ultimately there may be several contributory factors.




        Difficulties arise because:
        •    there are so many possible causes

        •    the  back  pain  may  be  a  primary  condition  or  it  may  be  secondary  to  another,  as  yet

             undiagnosed, problem, e.g. hock pain
        •    it is not possible to directly palpate the vertebrae with the exception of the dorsal spinous

             processes
        •    obtaining images of the back is expensive and requires good equipment and expertise due

             to the amount of soft tissue around the spine.
