This condition is typically caused by factors such as a firm mattress or fasciitis. Common causes of the above symptoms include fatigue, an overly firm mattress, or improper sleeping posture. It may also result from chronic lumbar injury due to intense physical activity or from lumbar–dorsal fasciitis. Low back pain can occur when lying down in a cold environment, as cold exposure acts as a trigger. Additionally, some patients present with structural abnormalities of the lumbar spine, such as severe anterior pelvic tilt. Prolonged bed rest may lead to lumbar muscle tension and subsequent low back pain.
