Numbness of any part of the body probably at least once affected every person. Very often limbs are affected by this phenomenon - arms, legs, fingers. The sensations of numbness are most often difficult to call pleasant. It is characterized by tickling, sipping, pain and all the known "goosebumps". And very often it is a symptom of the disease. Let's find out why the finger on the left hand is numb .
The most important and perhaps the most common cause of this phenomenon is a disease such as spinal osteochondrosis. With it, the disks turn out to be deformed, flattened and under their own weight they can press down the nerve endings, which, in turn, lead to the limbs. The condition is especially aggravated if osteochondrosis passes into a hernia, and since it most often manifests itself on one side, the fingers of just one hand suffer. And often left.
This disease will also be accompanied by weakness in the hands from the forearm to the elbow and pain in the spine. Therefore, if you are tormented by the question of
why the finger on the left hand is numb, you should first contact a surgeon or an osteopath and find out the condition of your spine.
Cause
Another disease with a similar symptom is the recent carpal tunnel syndrome. He is known to many people who spend a long time at the computer. But usually in this case, two fingers of the left hand immediately go numb, and not one, or even the entire brush. And, of course, such a disease is characteristic of lefties and ambidextras.
But there are also cases when it is worth seriously worrying about why the finger on the left hand is numb. This needs to be done when it comes to the little finger. His numbness may indicate the need to visit a cardiologist. After all, this can be a symptom of diseases such as angina pectoris, heart failure or hypertension.
Raynaud's disease
Another cause of numbness of the hand or one finger can be such an ailment as Raynaud's disease. It is characterized by paroxysmal circulatory disorders in the limbs. The disease is hereditary, and sometimes professional. Most often, female pianists are exposed to him, and again, those who work with computers.
This disease is also characterized by rapid freezing of the hands and feet, and without proper treatment can spread to the nose, ears, chin. Another characteristic symptom of it is the blueing of diseased parts of the body.
Vitamin deficiency
But if the middle finger of the left hand is numb, it may mean that you are lacking in vitamins. In particular, groups A and B. Such a symptom is especially relevant in the winter season. Although then it is easy to confuse it with the usual hypothermia of the extremities, because the main reason why the finger is numb on the left hand, as well as on the right, is this time of year. You should especially worry if, in addition to tingling and loss of sensation, the finger turns red and then lilac - this is a sure sign of frostbite. But jokes with him are bad - you can easily bring matters to the loss of a limb.
