Why do my fingers and toes feel stiff when I don't move them?

Stiffness in your fingers and toes when not in use can be caused by several factors, including reduced blood circulation, muscle fatigue, or joint stiffness. Prolonged immobility can lead to a buildup of lactic acid in the muscles, contributing to discomfort. Additionally, conditions like Arthritis or nerve compression could also lead to a sensation of stiffness. Regular movement and stretching can help alleviate this feeling.
