Rheumatoid Arthritis

A chronic inflammatory condition, rheumatoid arthritis can harm more than just your joints. Skin, eyes, lungs, heart, and blood vessels are just a few of the physiological systems that the illness might harm in certain people. Rheumatoid arthritis is an autoimmune illness that develops when your immune system unintentionally targets the tissues in your own body. Rheumatoid arthritis damages the lining of your joints, resulting in a painful swelling that may eventually lead to bone erosion and joint deformity, unlike osteoarthritis, which causes damage from wear and strain. Rheumatoid arthritis-related inflammation is what causes harm to other bodily components as well. Even with the tremendous improvements in treatment choices brought about by new drug classes, severe rheumatoid arthritis can still result in physical impairments.

Rheumatoid arthritis affects the joints in around 40% of patients, although other signs and symptoms can also occur. Potentially impacted areas include:

• Skin
• Eyes
• Lungs
• Heart
• Kidneys
• Salivary glands
• Nerve tissue
• Bone marrow
• Blood vessels

Knee discomfort can be brought on by mechanical issues, different forms of arthritis, and other issues.

• A knee injury can impact not just the bones, cartilage, and ligaments that make up the joint itself but also any ligaments, tendons, or bursae surrounding your knee joint.
• Mechanical problems. Direct trauma to the knee, rapid movements that strain it, or osteoarthritis in the knee brought on by component wear and tear are all examples of mechanical knee disorders. Certain rheumatic conditions, such as rheumatoid arthritis and systemic lupus erythematosus, can cause inflammatory knee difficulties (lupus).
• Arthritis is the medical term for swelling or joint inflammation. It encompasses more than 100 ailments impacting connective tissues, joints, and surrounding tissues. Depending on the kind of arthritis, specific symptoms might vary, although stiffness and joint pain are typically present.
