Knee pain that worsens at night may be linked to wear and tear, inflammation, swelling or excessive physical activity.
According to the Cleveland Clinic, wear and tear can cause discomfort after a long day, while inflammation may lead to soreness and stiffness. Swelling can also make movement uncomfortable.
Excessive activity may strain the knee, while exercise or injury can irritate the area around the kneecap. Remaining still for hours may cause stiffness.
