Post-thrombotic hand numbness generally refers to the symptom of hand numbness after cerebral infarction, which may be recovered if the condition is mild and effectively treated at an early stage, but is difficult to recover anyway. Numbness of hand after cerebral infarction belongs to post-stroke sensory disorder. After cerebral infarction, the cerebral sensory cortex and sensory conduction pathway are damaged, and then the limbs will be numb on the side, including numbness of the hand. Thrombolytic therapy is needed in the early stage of the disease, and when the condition is stabilized, the main application of anti-platelet aggregation, lipid regulation and other medications, such as aspirin, atorvastatin calcium tablets and so on. If the condition is mild, the treatment is timely and effective, and the nerve function recovers well, the hand numbness symptom may be completely recovered. If the condition is serious, or without timely and effective treatment, it may leave sequelae, and the symptoms of hand numbness are difficult to improve completely, and may exist for a long time. Therefore, patients with hand numbness symptoms after cerebral infarction should actively cooperate with professional doctors for systematic treatment and early control of the condition in order to improve the symptoms and avoid the sequelae.
