Feeling tingling or numbness in the feet is a sign of neurological disorder. The numbness is caused by the compression of some nerve or the artery that irrigates this nerve. The sensation of having your feet, hands or other part of your body numb or tingling is called paresthesia.
Drowsiness in the feet or toes is a symptom frequently observed in peripheral neuropathies. A neuropathy is an injury to a peripheral nerve, which are the channels of information transmission between the body and the brain.
The peripheral nervous system is formed by several nerves that receive and transmit nerve impulses to and from the spinal cord. This, in turn, is the channel that connects the brain to the nerves and vice versa.
In addition to stimulating the muscles to perform tasks and movements, the nerves also transmit sensations to the brain temperature (cold hot), pain, burning, burning, tact, pressure, among others.
Thus, when there is an injury to one of the nerves that transmits this information from the feet to the brain, interference or interruption occurs in the transmission of these impulses. The result is tingling or numbness in the feet, fingers, or tip of the toes.
The numbness in the feet can also be caused by herniated disc in the lumbar spine. The extravasation of the gel content of the intervertebral disc, which characterizes the hernia, can compress the root of the sciatic nerve and cause tingling and numbness in the buttocks (buttocks), thighs, legs and feet.
THE poor circulation resulting from vascular diseases, such as varicose veins, only causes numbness in the foot if the blood vessels fail to nourish the nerve. Paresthesia in this case would be caused by injury or death of the peripheral nerve due to lack of irrigation.
Seek a neurologist if you feel numb feet frequently, even if the sensation is fleeting and disappears spontaneously. It is worth remembering that some neurological diseases can cause progressive outbreaks from time to time without manifesting symptoms in the intervals.
