This is a 3-part Blog that looks at some of the more common concerns providers have when treating patients who present with back pain. In Part 1 we will look at acute non-traumatic musculoskeletal origins of back pain. We talk about key historical, physical exam, diagnostic imaging and treatment options that are associated with MSK back pain. In Part 2 we focus on neurologic origins the back pain. We address historical, physical exam, diagnostic imaging and treatment options used to treat neurologic origin back pain. We will provide recommendations for follow up care based on physical exam findings that involve only sensory and motor changes and those urgent presentations that demand your immediate attention. Finally, in Part 3 we address those emergent non-spine origins for back pain. Providers should be aware that abdominal aortic aneurysms (AAA), acute cholangitis, and retroperitoneal hematomas can present as back pain.
