We welcome you to the Rizash Inc, If you or a loved one has joint pain or is suffering from the debilitating disease of Arthritis, you're in the right place. Here you'll find information on understanding and treating Arthritis. The term “arthritis” literally means inflammation of a joint, but is generally used to describe any condition in which there is damage to the cartilage. Cartilage is the slippery tissue that covers the ends of bones in a joint. Healthy cartilage allows bones to glide over one another. It also absorbs energy from the shock of physical movement. In Arthritis, the surface layer of cartilage breaks down and wears away. This allows bones under the cartilage to rub together, causing pain, swelling, and loss of motion of the joint.   Learn More
