Hand swelling occurs in patients after cerebral infarction mainly due to limb motor dysfunction, which in turn causes obstruction of venous return, sympathetic nerve dysfunction, as well as electrolyte disorders or hypoproteinemia, and limb swelling occurs. Hand swelling after cerebral infarction is actually a common symptom of such patients, especially in the elderly who are very prone to it. After cerebral infarction, there are limb dysfunction, hemiplegia, muscle relaxation of the upper limbs, shoulder joint subluxation, and prolonged prolapse leading to unfavorable venous return and hand swelling. In addition, it is easy to combine with sympathetic nerve dysfunction, which can also be manifested as hand swelling. Cerebral infarction may also be combined with electrolyte disorders or hypoproteinemia, etc., which will cause osmotic pressure changes and thus hand swelling symptoms. There are many reasons for hand swelling after cerebral infarction, and it is necessary to consult the doctor in time for standardized treatment to avoid pain and joint stiffness, which will aggravate the difficulty of hand function recovery.
