In the case of swelling of the hands and feet in patients with cerebral infarction, it is necessary to distinguish whether it is bilateral or unilateral. If the swelling occurs in both limbs, it is necessary to look for systemic causes, such as low protein, whether there are lesions in the heart, kidneys, liver, etc. or other conditions. If the swelling is unilateral, i.e. on the affected side, the edema on the side where the patient has unfavorable movement is often due to unfavorable limb movement paralysis, resulting in local blood stagnation and swelling, which can often be relieved after elevating the affected limb. However, there are some cases that cannot be missed, namely, deep vein thrombosis may occur in the affected limb, and deep vein ultrasound should be performed to exclude thrombosis after edema occurs. If a patient has swelling of the affected limb with joint pain, think of shoulder-hand syndrome. Shoulder-hand syndrome usually appears 1-3 months after a stroke, with an incidence of 12.5%-70%. For patients with shoulder-hand syndrome, good limb positioning is very effective in avoiding shoulder-hand syndrome. In addition, patients can undergo rehabilitation, acupuncture, and massage for relief. In conclusion, for the swelling of the limbs in patients with cerebral infarction, it is important to further visit the hospital for appropriate treatment after the doctor determines the cause.
