Sleeping with legs crossed is a personal habit, not a disease, and there are many patients who have similar clinical manifestations and no other symptoms accompanying them, so just observe the condition. There is a clinical condition called restless leg syndrome, also known as restless leg syndrome. Patients with this condition feel that their legs have nowhere to rest, with soreness, numbness, swelling, pain, and a feeling of pins and needles and itching. When sleeping at night, they will unconsciously shake their legs, and the only way to relieve the discomfort of their legs is to do this action, so patients will unconsciously shake their legs at night, but crossing their legs does not belong to this disease. So patients just need to observe their condition and have other symptoms accompanying them can choose to visit the hospital.
