Spinning Out of Control: A 19-Year-Old Female with Spinning-Related Exertional Thigh Compartment Syndrome.Thigh compartment syndrome (TCS) is a rare condition caused by high pressures within the fascial compartments of the thigh, impeding capillary flow and leading to decreased perfusion, tissue hypoxia, and necrosis.  We present the case of a 19-year-old female who reported painful swelling in her thighs and darkening of her urine after participating in a spinning class.
