Why is your rotator cup injury more painful at night?

Rotator cuff injuries often become more painful at night due to several factors. When lying down, pressure on the shoulder can exacerbate inflammation and irritation in the injured area. Additionally, the body's natural production of anti-inflammatory hormones decreases during sleep, which may lead to increased pain perception. Finally, nighttime inactivity can lead to stiffness, making any movement or pressure on the shoulder feel more painful.
