Joints naturally accrue nitrogen bubbles over time, because of the synovial fluid that serves as a lubricant for them. As the pressure due to nitrogen increases, more nitrogen dissolves into the tissues. When nitrogen (N 2) gas forms bubbles, it accumulates and saturates the muscles and blood, causing pain.
