Hand numbness can indicate serious health problems
Numbness can be a harmless symptom, but it can also indicate serious problems (myocardial ischemia, stroke, herniated disc, diabetes, rheumatoid arthritis, etc.),
In the event that your hands become numb, you should see a neurologist, who can, if necessary, refer you to other medical professionals. In order to identify the disease's underlying causes, radiography, electromyography, magnetic resonance, and computed tomography may be required.
Fingers on the limbs can become numb due to a lack of B vitamins in the body or as a result of drinking large amounts of alcohol.
