Why is the little finger of the right hand numb ? With the development of the Internet, a lot of information on medical topics has appeared in the public domain. Moreover, everyone seeks to express their point of view on any issue. So it is with the situation when the little finger of the right hand is numb. Some say that the problem is with heart problems, the second is called osteochondrosis, and the third blame tunnel syndrome of the wrists. But in order to understand the reason, one must first understand what numbness is.
What is paresthesia
Numbness in the language of doctors is called paresthesia. It indicates a violation of the functioning of nerve endings. That is why the little finger of the right hand or the left is numb. The cause of paresthesia is a violation of blood circulation due to an uncomfortable posture, bumps or squeezing. Chronic paresthesia can be caused by diseases of the nervous system, tumors and infections, as well as alcohol abuse. In some cases, the little finger is numb on the arm due to metabolic or vitamin deficiency.
Features of the nervous system
The nervous system has a central and peripheral departments. Through the brain and back, the pairs of nerves that form the plexus pass. One of these plexuses is the brachial. It consists of 8 short and 6 long nerves. Short nerves in no way relate to a situation where the little finger of the right hand is numb. But one of the nerves, called the ulnar, branches into the back and palmar branches. This is the back branch and is responsible for the nerve endings of the fingers. The ulnar nerve passes through the joint and wrist, so pinching it in any part can disrupt the sensitivity of the little finger. To determine the exact cause of numbness, an MRI of the cervical spine is usually performed. In addition, injuries of the shoulder, wrist, and elbow contribute to numbness, even if they have long been left in the past.
Features of tunnel neuropathy
Another reason may be the constant compression of the now peripheral nerve as a result of physical exertion. In the human body there are veins and arteries. The latter carry blood enriched with oxygen from the heart, it is thanks to it that all processes in the body are supported. Veins, on the contrary, serve to circulate blood saturated with decay products. An artery originating near the clavicle later branches into the ulnar and radial. Beam contains
superficial and deep branches that supply oxygen to the wrist and hand. But circulatory disorders can lead to a lack of oxygen, resulting in
numbness of the fingers. The cause of oxygen deficiency can be blood clots, plaques resulting from atherosclerosis, as well as trauma.
Therefore, we can conclude that the cause of the condition in which the little finger is numb on the right hand is, as a rule, diseases of the nervous or vascular system. No osteochondrosis, heart disease has nothing to do with it. With the right diagnostic examination, proper treatment, elimination of an old trauma, the symptoms of numbness will disappear quickly and without a trace, while you forget that you had something with a finger there.
