Tingling sensations are abnormal sensations that can occur in any part of the body, but they are often felt in the fingers, hands, feet, arms or legs. Who has not ever fallen asleep or felt a tingling in the hand? What are its causes and when do you have to worry about them?
In an interview with Infosalus, the family doctor and member of the Neurology Working Group of the Spanish Society of Family and Community Medicine (SEMFYC), Dr. Jesus Pujol states that at a medical level tingling is known as ‘paresthesia’.
“The tingling may appear good by the posture we maintain, or as a symptom of a disease. One of the most common factors is the postural, staying in the same position for a long time and then, secondly, due to the injury of a nerve and for example the pressure on the nerves. of a herniated disc, “he says.
The specialist of the health center of Balaguer (Lleida) also points to the lack of vitamin B12; at abnormal levels of calcium, potassium or sodium in the body; to the use of certain medicines; to diabetes mellitus; to chemotherapy or radiotherapy treatments; by atherosclerosis or by a freezing or inflammation of the blood vessels; as a result of the bite of an animal or insect; or by toxins in seafood.
On the diseases that can generate paresthesias, Dr. Pujol points to carpal tunnel syndrome, migraines, hypothyroidism, multiple sclerosis (ALS), epileptic seizures or cerebrovascular accidents, in addition to Raynaud’s phenomenon ( a narrowing of the blood vessels by poor regulation of temperature in the hands and feet).

Pujol also distinguishes between paresthesias or episodic tingling, of the permanent ones. “The episodic are derived from nerve compression, as for example happens in the herniated discs at any point of the spine, in the case of postural and carpal tunnel syndrome. Instead, they are permanent when they are derived from a deficiency of vitamin B12, or are caused by diabetes mellitus, or by neurological diseases such as ALS, “adds the member of SEMFYC.
In his opinion, there is no need to be scared when the tingling suddenly appears. It is convenient to see a doctor when there is also a weakness or inability to move at the same time as paresthesia itself.
It also recommends going to a Primary Care doctor if the tingling arises just after having suffered an injury or trauma to the head, neck or back; if they appear at the same time that the movement of the leg or arm can not be controlled; or if there is also a loss in sphincter control; or at the same time that the tingling is difficult to talk, changes in vision, difficulty or weakness to walk, there are skin rashes, or any unusual symptom in the person and that is accompanied by tingling.
The treatment, according to Pujol, will depend on what is the cause that has given rise to these paresthesias and if, for example, it is due to a deficiency of vitamin B 12, it will be advised in that case to take supplements of the said vitamin. The prognosis of paresthesia depends on the severity of the sensations and associated disorders.
