👉 Finger fluid, also known as digital fluid or synovial fluid, is a clear, viscous liquid found in the spaces between the fingers and toes. It plays a crucial role in joint health by lubricating and cushioning the joints, allowing for smooth, pain-free movement. Produced by the synovial membranes lining the joints, this fluid contains hyaluronic acid, which reduces friction and absorbs shock. When the fluid is healthy, it helps maintain joint flexibility and mobility; however, factors like aging, injury, or autoimmune conditions can lead to reduced fluid production or increased evaporation, potentially causing joint stiffness and discomfort.
