Swelling of the fingers around the age of 50 may be caused by overwork, but it can not be ruled out that it is caused by superior vena cava obstruction syndrome, synovial lesions and other etiological factors, and should be promptly consulted to find out the cause of the disease. 1. Overwork: It is possible that the fingers are overworked and overstrained, resulting in fatigue inflammation of the muscles, joint capsules and ligaments of the fingers, i.e., fatigue caused by frequent use of the hands or weight bearing in the working environment, which may result in finger swelling. 2. Superior vena cava obstruction syndrome: due to the anatomical characteristics of the superior vena cava, the superior vena cava can be narrowed by external pressure, such as tumor compression, mediastinal inflammation, etc. The resistance of the blood in the upper body to flow back to the heart increases, and edema, including finger swelling, can occur if the returning blood is not smooth. 3. synovial lesions: such as hands for a long time in the wet and cold environment, frequent strenuous activities, will lead to synovial edema and synovitis, commonly degenerative synovitis caused by specific pathologic synovial lesions. 50 years old, with the growth of age, hormone level changes, compensatory finger swelling can occur. Finger swelling around the age of 50 may also be finger stenosing tenosynovitis, rheumatoid joints and late complications of diabetes mellitus, etc. If you exclude physiological causes, you should consult a doctor in a timely manner, ask the doctor to clarify the specific cause, and if necessary, carry out the appropriate treatment.
