3. There are more than 100 types of arthritis
Here are some of the most common:
Osteoarthritis (OA) is by far the most common type of arthritis. Rheumatoid arthritis (RA) is the most common type of inflammatory arthritis, and usually affects many joints in the body. Fibromyalgia’s main features are severe and widespread muscle pain that is most pronounced in the neck and shoulders, extreme fatigue and—in most cases—poor sleep. Fibromyalgia can feel like a joint disease, but the pain actually occurs in nearby muscles, ligaments and tendons.
Ankylosing spondylitis (AS) is a chronic inflammation of the spine, and is mainly a disease of young people, often beginning before age 20 and rarely affecting people over 40.
Systematic lupus erythematosus (lupus) is a chronic disease that usually inflames the joints—and also affects the skin, kidneys, blood vessels, nervous system and virtually every other organ in the body.
Other types of arthritis include:
• Reiter’s syndrome
• Psoriatic arthritis
• Lyme arthritis
