paresthesia
Definition
Noun: A sensation of tingling, tickling, itching, or burning on the skin, typically occurring without an external stimulus and often associated with nerve damage or dysfunction.
Examples
- The patient reported paresthesia in her fingertips, describing it as a persistent "pins and needles" feeling.
- Temporary paresthesia can occur when you sit in one position for too long and a nerve is compressed.
- A common symptom of carpal tunnel syndrome is paresthesia in the thumb and first two fingers.
Advanced Usage
- Medical Context: The term is primarily used in clinical and neurological contexts to describe a specific symptom. It is often qualified by its location (e.g., facial paresthesia) or described as transient or chronic.
- The neurologist documented chronic paresthesia in the lower limbs.
- Distinction from Dysesthesia: While both are abnormal sensations, paresthesia typically refers to spontaneous, painless sensations like tingling. Dysesthesia often implies a more unpleasant, painful, or distorted sensation, such as feeling a light touch as burning.
