Cerebral infarction patients with body pain and weakness may be related to poor sleep, and may also be caused by symptoms of cerebral infarction and limb spasm. 1. Poor sleep: patients with cerebral infarction often suffer from various physical discomforts that affect their sleep, resulting in poor sleep quality and insufficient sleep time. When sleeping for a long time, the brain and the body cannot get sufficient and reasonable rest, which may show pain and weakness of the body, and may be accompanied by dizziness, headache and other symptoms. 2. Symptoms of cerebral infarction: After cerebral infarction patients suffer from ischemia and hypoxia in the brain, brain tissue damage and nerve conduction bundle damage, it often leads to sensory abnormality in the contralateral limbs of the patients, which may show pain and weakness all over the body. 3. Limb spasm: patients with cerebral infarction who have been bedridden for a long time may have limb spasm, which may be manifested as pain and weakness all over the body. Cerebral infarction patients with body pain and weakness may also be caused by other reasons. If the patient’s discomfort continues to be unrelieved, he should consult a doctor as soon as possible to confirm the diagnosis of the causative factors, and then be guided by the doctor to carry out the treatment.
