In this episode we go through seven cases that display the breadth of presentations of limb or life threatening causes of low back pain emergencies with my huge mentors, Dr. Walter Himmel and Dr. Brian Steinhart. We cover everything from spinal epidural abscess to cauda equina syndrome to retroperitoneal bleeds, elucidating the key historical, physical exam, lab, imaging and treatment pearls for all of these diagnoses. We then go on to review the best management for the most common cause of back pain presentation, lumbosacral strain and debate the various medication options.
