The sensation of numbness in the fingers is probably familiar to every person. If this is observed after sleep, it is most likely that numbness is associated with prolonged exposure to an uncomfortable posture, at which the hands are squeezed, and it is quickly removed after a gentle massage of the hands. But if the fingertips on the hands regularly numb irrespective of external influences, then the reasons should be sought in more serious factors. Let's consider why the fingertips on your hands can dumb, what are the reasons for this most common.
The main reasons why fingertips on the hands

A very common cause of loss of sensitivity, sensation of numbness, tingling, cooling in the tops of the fingers can be osteochondrosis of the cervical spine. With this disease, the cartilaginous tissue of the intervertebral discs is affected and there may be a related pinching of the nerves, resulting in numbness. It is the problems with the spine that are more often the cause of why the fingertips are numb only on the left or only on the right arm, bilateral bilateral numbness occurs very rarely in such cases.
Polyneuropathy
Another possible cause is polyneuropathy , a pathology in which peripheral nerves are affected due to infectious, intoxicating factors, metabolic disorders, etc. It is also possible:

- motor disorders;
- muscle weakness, etc.

- endocrine disorders;
- stress;
- frequent hypothermia of the hands, etc.
Pregnancy

As a rule, after giving birth, unpleasant sensations pass independently.
Vegetosovascular dystonia
If finger tips grow numb, one more reason for this may be vegeto-vascular dystonia, a symptom complex associated with a violation of neuroregulation. At the given pathology also such manifestations are noted:
- sweating of the palms and feet, their chilliness;
