Verdict: FALSE
A sometimes very banal origin
Staying in the same position for a long time can temporarily compress a nerve. This is what explains why an arm or a leg “falls asleep”.
In this situation, the tingling disappears quickly when circulation and nerve conduction return to normal.
But other causes exist
When these sensations become frequent or persist, they can have many origins.
Certain neurological diseases, circulation disorders, diabetes or nutritional deficiencies are among the possible causes.
The doctor is interested in the location, duration of episodes and other associated symptoms.
Signs that require a consultation
Tingling accompanied by muscle weakness, significant loss of sensitivity, difficulty speaking or balance problems should prompt consultation.
Conversely, a limb that “falls asleep” a few minutes after a bad position is generally not serious.
What to remember
Tingling isn’t always due to a pinched nerve. When they become repeated or are accompanied by other symptoms, they require medical evaluation.
Advice from Dr Gérald Kierzek
In the event of tingling in the upper limb, it may be cervico-brachial neuralgia with pain that starts from the neck and radiates into the arm, hand or fingers, often linked to irritation or compression of a nerve root in the cervical vertebrae (herniated disc, osteoarthritis, trauma, etc.). It may be accompanied by tingling, loss of strength or sensitivity in the arm and requires medical advice to confirm the diagnosis, relieve pain and avoid complications.
