Weakness and tenderness in half of the body is considered more likely to be cerebrovascular disease. Cerebrovascular disease is mostly sudden and eccentric, often accompanied by panic, chest tightness, headache, vomiting and hemiplegia of the limbs. For sudden onset of hemiplegia and weakness, it is recommended to consult a doctor for a CT or MRI of the head to determine whether it is a cerebrovascular disease, hemorrhagic or ischaemic cerebrovascular disease.
