关节原因joint stiffness。当组织和软骨肿胀时，关节不能自由移动。
Joint stiffness is especially common早晨when you haven’t used the joint in several hours. It also occurs after a long day of movement or work when the joints have been under more stress than usual.
The cartilage in your joints can wear away unevenly. Additionally, the tissues andligamentsdesigned to hold the joints in place grow weaker as arthritis progresses. These two developments can cause deformities in your fingers and hands.

A layer of cartilage covers and cushions the bones in a healthy joint. In an arthritic joint, the cartilage is worn away and disappears altogether.

This will be painful, and the loss of cartilage will appear inX-rays作为一个loss of joint space。
When a joint is damaged, ligaments and tissues around the joint can become inflamed. This inflammation will cause the joint to feelwarm。
It may also cause redness around the joint.
