Of more than 100 different kinds of arthritis, these are the most common types and their symptoms:
Osteoarthritis Arthritis Symptoms
Osteoarthritis is a condition in which low-grade inflammation results in pain in the joints, caused by wearing of the cartilage that covers and acts as a cushion inside joints. As the bone surfaces become less well protected by cartilage, the patient experiences pain upon weight bearing, including walking and standing. Due to decreased movement because of the pain, regional muscles may atrophy, and ligaments may become more lax. OA is the most common form of arthritis. The word is derived from the Greek word "osteo", meaning "of the bone", "arthro", meaning "joint", and "itis", meaning inflammation, although many sufferers have little or no inflammation.

Rheumatoid Arthritis Symptoms
Rheumatoid arthritis (RA) is traditionally considered a chronic, inflammatory autoimmune disorder that causes the immune system to attack the joints. It is a disabling and painful inflammatory condition, which can lead to substantial loss of mobility due to pain and joint destruction. RA is a systemic disease, often affecting extra-articular tissues throughout the body including the skin, blood vessels, heart, lungs, and muscles. About 60% of RA patients are unable to work 10 years after the onset of their disease.

Gout Arthritis Symptoms
Causes sudden, severe attacks, usually in the big toe, but any joint can be affected. A metabolic disorder in which uric acid builds up in the blood and crystals form in joints and other places. Drugs and attention to diet can control gout. Affects about 1 million Americans (70 to 80 percent men), with first attack starting between 40 and 50 years of age.

Ankylosing Spondylitis Arthritis Symptoms
A chronic inflammatory disease of the spine that can result in fused vertebrae and rigid spine. Often milder and harder to diagnose in women. Most people with the disease also have a genetic marker known as HLA-B27. Affects about 318,000 Americans, usually men between the ages of 16 and 35.

Juvenile Arthritis Symptoms
The most common form is juvenile rheumatoid arthritis. Arthritis diagnosis, treatment, and disease characteristics are different in children and adults. Some children recover completely; others remain affected throughout their lives. Affects about 200,000 Americans.

Psoriatic Arthritis Symptoms
Bone and other joint tissues become inflamed, and, like rheumatoid arthritis, it can affect the whole body. Affects about 5 percent of people with psoriasis, a chronic skin disease. Likely to affect fingers or spine. Symptoms are mild in most people but can be quite severe. Affects about 160,000 Americans.

Systemic Lupus Erythematosus Symptoms
Involves skin, joints, muscles, and sometimes internal organs. Symptoms usually appear in women of childbearing age but can occur in anyone at any age. Also called lupus or SLE, it can be mild or life threatening. Affects at least 131,000 Americans, nine to ten times as many women as men.

Septic arthritis is the invasion of the joint space by an infectious agent which produces arthritis. The usual etiology is bacterial, but viral, mycobacterial, and fungal arthritis occur occasionally. Bacteria are either carried by the bloodstream from an infectious focus elsewhere, introduced by a skin lesion that penetrates the joint, or by extension from adjacent tissue (e.g. bone or bursae).

Arthritis can develop as a result of an infection. For example, bacteria that cause gonorrhea or Lyme disease can cause arthritis. Infectious arthritis can cause serious damage, but usually clears up completely with antibiotics. Scleroderma is a systemic disease that involves the skin, but may include problems with blood vessels, joints, and internal organs. Fibromyalgia syndrome is soft-tissue rheumatism that doesn't lead to joint deformity, but affects an estimated 5 million Americans, mostly women. The approximate number of cases in the United States of some common forms of arthritis.
