Men’s arm veins, i.e. subcutaneous veins in the arms, can be physiologic (normal) or pathologic (caused by disease). Arm veins generally refers to varicose veins on the arm. Physiological varicose veins (veins) in the arms of boys are mostly related to excessive laborious activities or strong physical exercise, etc., while those with fair skin or relatively thin people have more obvious veins. Physiological varicose veins can be clarified by ultrasound or angiography. Generally, physiological varicose veins do not require special treatment, but if the varicose veins are particularly serious, they can be treated with surgery. Pathological varicose veins in men can be caused by venous thrombosis (which requires thrombolytic or thrombolytic treatment after relevant examinations), compression by swelling (which requires surgery to remove the swelling to relieve the compression), etc. Pathological varicose veins should be identified in a timely manner, and treated according to the cause of the disease.
