Arthritis is the inflammation of a joint, usually accompanied by pain, swelling, and stiffness, and resulting from infection, trauma, degenerative changes, metabolic disturbances, or other causes. It occurs in various forms, such as bacterial arthritis, osteoarthritis, or rheumatoid arthritis.
What are the symptoms?
The main symptoms of arthritis are pain, stiffness, and swelling in the joints of the hands, wrists, elbows, feet, ankles, knees, or neck. The disease usually affects both sides of the body at the same time.
What are the causes?
The pain associated with arthritis is caused by joint damage. There are two main types of arthritis that damage joints in different ways.
Osteoarthritis causes wear-and-tear damage to cartilage can result in bone grinding directly on bone, which causes pain and restricts movement. This wear and tear can occur over many years, or it can be hastened by a joint injury or infection.
What is rheumatoid arthritis?
In rheumatoid arthritis, the body's immune system attacks joints causing swelling, redness and pain. The disease can eventually destroy cartilage and bone within the joint.
