Have you experienced numbness in any part of your body? Are you wondering why it usually manifests with tingling sensation or pins and needles? Well, to answer the question on why numbness feels like tingling, the following discussion will explain what is numbness and the scientific mechanism of which leading to a feeling of tingling sensation, which you may have even felt before your last Land O Lakes chiropractor visit.
What is Numbness and what causes it?
Numbness is a feeling of abnormal sensations in any part of the body particularly in the hands, fingers, arms, legs and feet. It is characterized as reduced feeling of touch or pain. Numbness is one of the most common reasons why people seek the care of neurologists because some people may just be too worried about its presence. Numbness can be caused by a variety of conditions ranging from central nervous system disorders to peripheral nervous system conditions. Also, it may be caused by poor perfusion to one area of the body as well as infections in the form of shingles. Other causes may include vitamin B12 deficiency and direct injury to the nerves.
The main cause of numbness is the affectation of the flow of the nerve impulses from the peripheral areas of the body to the brain and vice versa. In the presence of central nervous system disorders such as spinal deformities, the peripheral nerves are impinged causing an alteration in the functioning of the affected nerves. Nerves both have sensory and motor function. When the fingertip is pricked for instance, the nerves send an electrical impulse to the brain signifying that pain is felt. As a response, the brain sends signals back to the nerves to allow the muscles to contract and pull the finger away from the source of pain. These series of functions are the daily events in a nerve.
In cases of numbness, there is less feeling of pressure, touch or pain. This is for the reason that the nerves are disrupted; thereby, the nerve signaling to the brain to interpret these feelings is impaired. But how about tingling
Tingling is an associated symptom of numbness and it occurs as a feeling of thousands of pins and needles pricking a particular body part at the same time.
Much like numbness, tingling sensations come from the disruption in the functioning of the nerves allowing you to feel that something is pricking you without any source of stimuli. This happens because of the rapid firing of nerve impulse transmission from the brain to the peripheral nerves and just like numbness, it results from the impingement, kinking, poor perfusion or reduced nutrition of the peripheral nerves.
Some peripheral nerve injuries or disruptions manifest as numbness wherein there is reduced sensation to a particular body part. In other circumstances, the nerves send electrical signals in disrupted forms leading to the brain interpreting it wrongly and allowing you to feel pins and needles without apparent source of stimuli.
Numbness and tingling sensations often come together. While they are common complaints, it is generally advised to seek medical consult especially if you feel these sensations along with weakness and pain to rule out possible serious conditions leading to such.
