Osteoarthritis is diagnosed when the pain in shoulder joints is caused when the cartilage in the shoulder begins to wear down.  Because of this, osteoarthritis is often called "degenerative arthritis."  This is most common among older patients with pain in shoulder joints.

When the bursae in the joints wear down, there is no longer the soft cushion to help assist the gliding motion.  Without a healthy bursa, the bones begin to rub on each other, causing the pain in the shoulder joint.  Without the cartilage, the shoulder is no longer able to move fluidly.  This is the cause for the stiffness of osteoarthritis.

One of the best ways to ease the pain and to allow for healing time is to take a good, all-natural anti-inflammatory such as Celadrin.  Natural anti-inflammatories are non habit-forming and more effective.
