Rheumatoid arthritis is a widespread inflammatory disease that primarily involves the synovial membrane (which can later spread to articular cartilage, bone tissue, joint ligaments and muscle bonds) and to a lesser extent the connective tissues of the plasma membrane, heart, lungs and eyes. The systemic manifestations of rheumatoid arthritis include fever, fatigue, pericarditis, subcutaneous nodules, pleurisy, arteritis, and peripheral neuropathy, in addition to joint lesions. In addition to inflammatory lesions in the joints, rheumatoid arthritis in the broad sense also includes extensive lesions throughout the body. 1, reasonable diet.
