The median nerve of forearm and upper arm is numb in palm, thumb, forefinger and middle finger due to trauma, tumor and compression. Wrist is the most vulnerable to injury or compression, which is called carpal tunnel syndrome.
If middle-aged and elderly people have persistent thumb numbness, such as local oppression for too long, after catching a cold, some feel like acupuncture, and some feel heavy or unconscious, they will generally disappear soon.
If the numbness lasts too long or the symptoms get worse, you can see that the appearance is normal when you go to see a doctor, and there is no special finding in the examination. You are often diagnosed with neuritis or peripheral neuritis. And take some B vitamins or orally. Although some people can get better, some people have not improved, especially after middle-aged and elderly people. This is because middle-aged and elderly people will feel a numb thumb, which is often an ominous sign of stroke.
In this case, you must not be careless. To check blood pressure, blood lipid, blood sugar and fundus, it is best to ask a neurologist to do a detailed examination to prevent problems before they happen.
If the microcirculation is not good, you can eat Danshen tablets.
