Exertional limb pain is a common problem encountered in recreational and competitive athletes. Affecting both the upper and lower extremities, this broad entity can be musculoskeletal, vascular, neurologic, oncologic, or infectious in origin. This article focuses on the vascular causes of exercise-related extremity pain, which encompass a cadre of elusive diagnoses. Specifically, we examine arterial endofibrosis, popliteal artery entrapment syndrome, and chronic exertional compartment syndrome of both the upper and lower extremities. For each of these conditions, we offer updates regarding the respective epidemiology, common signs and symptoms, worthwhile diagnostic modalities, and pertinent treatment options, all based on evidence and reports published over the past year.
