Quick Answer
Osteoarthritis is wear-and-tear degeneration; rheumatoid arthritis is autoimmune inflammation. The distinction fundamentally changes treatment approach.

Osteoarthritis (OA) and rheumatoid arthritis (RA) are the two most common forms of arthritis, yet they are fundamentally different conditions with different causes, mechanisms, and treatments. Understanding the distinction is crucial because mistaking one for the other can lead to inappropriate treatment and preventable joint damage.
Osteoarthritis is a degenerative condition caused by mechanical wear and tear on joint cartilage. It most commonly affects weight-bearing joints (knees, hips) and the hands. Risk factors include age, obesity, joint injury, and repetitive mechanical stress. OA typically affects joints asymmetrically and produces pain that worsens with activity and improves with rest. Morning stiffness is brief (less than 30 minutes). X-rays show joint space narrowing, bone spurs, and subchondral sclerosis.

Rheumatoid arthritis is an autoimmune disease in which the immune system attacks the joint lining. It typically affects the small joints of the hands and feet symmetrically. Risk factors include genetic susceptibility (HLA-DR4), smoking, and female sex. RA pain is often worse in the morning and improves with movement. Morning stiffness typically exceeds 30 minutes. Blood tests show rheumatoid factor and/or anti-CCP antibodies, and elevated inflammatory markers.
Treatment differs significantly. OA management focuses on weight management, physical therapy, activity modification, topical and oral analgesics, and joint replacement when conservative measures fail. RA requires disease-modifying therapy (methotrexate, biologics) to suppress the underlying immune attack and prevent joint destruction. Misdiagnosing RA as OA and treating only with analgesics allows progressive joint erosion that could have been prevented.

No. RA is an autoimmune inflammatory condition, while osteoarthritis is a degenerative wear-and-tear condition. RA causes symmetric joint inflammation and systemic symptoms; osteoarthritis typically affects weight-bearing joints with mechanical pain.
There is currently no cure for RA, but with early and appropriate treatment, many patients achieve remission or good disease control. The goal of modern treatment is to prevent joint damage and maintain function.
Migraine is a neurological condition; headache is one feature. Associated symptoms and functional impact are important for diagnosis.
Aura refers to visual, sensory, or speech symptoms that precede the headache in some people. Both types are migraine; the presence of aura may influence management discussion.
