Rheumatoid arthritis is a chronic, autoimmune disorder that causes inflammation to smaller joints in the hands and feet. This particular form of arthritis affects the lining of joints, which can result in bone erosion and joint deformity overtime.
Rheumatoid Arthritis Causes
Inflammation and pain from this condition occurs when the immune system attacks the body’s tissues, specifically the synovium that surrounds the joints. Genetic and environmental factors are considered potential causes, in addition to infections from certain bacteria or viruses.
Rheumatoid Arthritis Symptoms
Rheumatoid arthritis tends to affect smaller joints, including the hands, wrists, elbows, shoulders, hips, knees, and ankles. Signs or symptoms of rheumatoid arthritis may include:
- Tender or swollen joints
- Pain or stiffness that is worse in the mornings
- Hard nodules under the skin on your arms
