paresthesia

Paresthesia is a sensation of abnormal skin feeling, such as tingling, numbness, prickling, or a "pins and needles" feeling. It occurs when nerves are irritated, compressed, or damaged, affecting how signals are sent to the brain. Paresthesia can happen temporarily, like when your limbs fall asleep, or persist due to underlying health conditions such as nerve disorders, circulation issues, or vitamin deficiencies. While often harmless if brief, persistent or frequent sensations should be evaluated by a healthcare professional to identify and address any underlying causes.
