She had been wearing tight ‘skinny’ jeans and recalled that these had felt increasingly tight and uncomfortable as the day wore on. Later that evening, she experienced numbness in her feet and found it difficult to walk, which caused her to trip and fall. Unable to get up, she spent several hours lying on the ground before she was found. Her calves were so swollen that her jeans had to be cut off her. She couldn’t move her ankles or toes properly and had lost feeling in her lower legs and feet. Investigations revealed that she had damaged muscle and nerve fibres in her lower legs as a result of prolonged compression while squatting, which her tight jeans had made worse, the doctors suggest. The jeans had prompted the development of compartment syndrome—reduced blood supply to the leg muscles, causing swelling of the muscles and compression of the adjacent nerves. She was put on an intravenous drip and after 4 days she could walk unaided again, and was discharged from hospital.
