Rheumatic diseases (i.e., rheumatic diseases) are chronic diseases that involve the bones, joints, and surrounding soft tissues, or involve other tissues and organs. It may present as a localized pathological injury or as a systemic disease. Degenerative joint disease, spondyloarthritis, and diffuse connective tissue disease are common, with some variability in the aura of different diseases. Mostly reflected in the joints, muscles, skin, mucous membranes and other aspects: 1. Joint performance: usually there will be local pain, redness and swelling, and some will appear joint hyperplasia and deformation. Muscle manifestations: muscle pain, muscle pressure, muscle atrophy, and decreased muscle strength may occur; 3, skin and mucous membrane manifestations: SLE may show symptoms such as cheek butterfly erythema, hair loss, oral ulcers, and photosensitivity; 4, vascular lesions: some diffuse connective tissue diseases may cause inflammation along the walls of large blood vessels, resulting in vessel wall thickening, lumen narrowing, and vasodilatation. The luminal narrowing and vasodilator dysfunction may lead to thrombosis, resulting in local tissue and organ ischemia; 5, Raynaud’s phenomenon: due to the lowering of temperature or emotional agitation will appear pale skin of the fingers and toes, followed by cyanosis and then turn flushed, may be accompanied by local chills and abnormal pain. It is mostly seen in diseases such as systemic sclerosis, systemic vasculitis, and systemic lupus erythematosus.
