The main difference between osteoarthritis and rheumatoid arthritis is the cause behind the joint symptoms. Osteoarthritis is caused by mechanical wear and tear on joints. Rheumatoid arthritis is an autoimmune disease in which the body's own immune system attacks the body's joints. It may begin any time in life.
RA is symmetrical, where a patient feels symptoms in the same spot on both sides of the body, often in the joints in the feet and hands. Osteoarthritis, in contrast, begins in an isolated joint, often in the knee, fingers, hands, spine and hips. While both sides may hurt, one side is more painful.
Can an X-ray show the difference between OA and RA? Yes. Joints in RA look different than joints in OA. That's why X-rays are a helpful tool for figuring out the cause of joint pain.
Imaging Tests
Doctors may use x-rays to monitor the progression of the disease or to rule out other causes for the joint pain. Magnetic resonance imaging (MRI) and ultrasound may help diagnose rheumatoid arthritis in the early stages of the disease.
Both involve inflammation in the joints, but RA causes much more inflammation.
Rheumatoid arthritis can be one of the most painful types of arthritis; it affects joints as well as other surrounding tissues, including organs. This inflammatory, autoimmune disease attacks healthy cells by mistake, causing painful swelling in the joints, like hands, wrists and knees.
No blood test can definitively prove or rule out a diagnosis of rheumatoid arthritis, but several tests can show indications of the condition. Some of the main blood tests used include: erythrocyte sedimentation rate (ESR) – which can help assess levels of inflammation in the body.
A person with RA may feel intense pain in their joints during flares. This can feel like sustained pressure, a burning sensation, or a sharp pain. However, people with RA may also experience periods of remission when they feel few to no symptoms. In addition to causing joint pain, RA can affect the whole body.
Pain from arthritis can be constant or it may come and go. It may occur when at rest or while moving. Pain may be in one part of the body or in many different parts. Some types of arthritis cause the skin over the affected joint to become red and swollen, feeling warm to the touch.
Both conditions cause joint pain, sure, but RA is systemic while OA is localized. But here's the rub: People with RA may also develop OA. Learn what it means to have this double-whammy diagnosis and how you can navigate OA with as much tenacity and grace as you do RA.
Clinical History. The typical case of rheumatoid arthritis begins insidiously, with the slow development of signs and symptoms over weeks to months. Often the patient first notices stiffness in one or more joints, usually accompanied by pain on movement and by tenderness in the joint.
The joint pain associated with rheumatoid arthritis is usually a throbbing and aching pain. It is often worse in the mornings and after a period of inactivity.
Blood, Fluid and Tissue Tests
Blood tests are not needed to diagnose all types of arthritis, but they help to confirm or exclude some forms of inflammatory arthritis. Your doctor may also draw joint fluid or do a skin or muscle biopsy to help diagnose certain forms of arthritis.
Although there's no blood test for osteoarthritis, certain tests can help rule out other causes of joint pain, such as rheumatoid arthritis. Joint fluid analysis. Your doctor might use a needle to draw fluid from an affected joint.
People describe it as being overwhelming and uncontrollable. They feel worn out and drained of energy, and sometimes even lose all interest in anything. It can increase the need for sleep and make it hard to concentrate or do anything.
For decades, X-rays were used to help detect rheumatoid arthritis (RA) and monitor for worsening bone damage. In the early stages of RA, however, X-rays may appear normal although the disease is active, making the films useful as a baseline but not much help in getting a timely diagnosis and treatment.
Fibromyalgia is not a form of arthritis (joint disease). It does not cause inflammation or damage to joints, muscles or other tissues. However, because fibromyalgia can cause chronic pain and fatigue similar to arthritis, some people may think of it as a rheumatic condition.
Osteoarthritis (OA) is the most common form of arthritis. Some people call it degenerative joint disease or “wear and tear” arthritis.
