Rheumatic diseases common symptoms and harm Rheumatic diseases mainly affect the body parts of the joints, muscles, bones and soft tissues around the joints, such as tendons, ligaments, bursae, fascia and other parts of the disease. Systemic damage: Autoimmune connective tissue diseases such as systemic lupus erythematosus rheumatoid arthritis can have damage to multiple organs, such as cardiac inflammation, kidney damage (proteinuria, hematuria, etc.), hematological system (leukopenia, erythrocytopenia, thrombocytopenia, blood tolerance, etc.), respiratory system (interstitial pneumonia, pulmonary hypertension, pleural effusion), digestive system ( liver function impairment, jaundice), etc. 2. skin and mucous membrane symptoms: systemic lupus erythematosus, dermatomyositis polymyositis, dry syndrome may have erythema and other specific rashes. 3. muscle: muscle pain, muscle weakness, elevated muscle enzymes, electromyography showing myogenic damage, etc., such as dermatomyositis polymyositis, mixed connective tissue disease, systemic lupus erythematosus, etc. 4. fever is a common symptom of rheumatic diseases, which can be low or moderate fever with ineffective antibiotics, along with fast blood sedimentation, such as systemic lupus erythematosus, adult Stearns disease, etc. can have fever as the first symptom. 5. Pain: Pain in joints, muscles and tendons is the most common symptom of rheumatism, mainly manifested as joint pain. Depending on the disease, the nature, location and degree of pain also vary, manifesting as heat pain, cold pain, soreness, swelling and wandering pain, mainly in the extremities. Swelling of joints: It is manifested as puffiness and swelling around the joints, and the swollen area is swollen and higher than the normal skin. There are many causes of swelling and its clinical manifestations are different, and it can occur in one or more joints, mainly in the limbs. Mobility disorders: manifested as restricted movement of the joints of the limbs and the spine, etc., and difficulty in flexion and extension, is one of the common symptoms of rheumatic diseases. The prognosis of the disease varies from disease to disease in terms of severity. Some mobility disorders are caused by pain, and as the pain is relieved, the mobility disorder disappears, such as the active phase of rheumatoid arthritis and the exacerbation of gouty arthritis. Some pain is not obvious, but still cannot perform normal activities, which suggests changes in the structure of the joints and the tissues around the joints, and the bones of the joints, such as rheumatoid arthritis, ankylosing spondylitis, and osteoarthritis. Morning stiffness: Many patients with rheumatic diseases feel stiffness and unfavorable flexion and extension in the morning, and this stiffness can be relieved after a period of activity. Most commonly seen in rheumatoid arthritis, ankylosing spondylitis, osteoarthritis and some strain and degenerative lesions. Numbness: a symptom of abnormal sensation or perceptual impairment of the patient’s skin, mostly seen in chronic rheumatic diseases such as cervical spondylosis, rheumatoid arthritis and osteoarthritis.
