Paresthesia is a sensation, usually felt on the skin, usually felt or described as numbness, tingling, pins and needles, or pricking. It is sometimes also known as having the arm, leg, or other body part "fall asleep." Continue reading for more information on these and other possible symptoms.
Paresthesia may be classified as either transient or chronic. Transient paresthesia may be a symptom of hyperventilation syndrome or a panic attack. Chronic paresthesia may result from poor circulation, nerve irritation, neuropathy, or many other conditions and causes. There is no known long-term physical effect from paresthesia (although its underlying conditions may have various effects).
Several causes and situations in which paresthesia might be found may include:
Carpal tunnel syndrome
Guillain-Barre Syndrome (GBS)
Herpes zoster (shingles)
Hypoglycemia (low blood sugar)
Multiple sclerosis (MS)
Transient ischemic attack (TIA)

Diagnosis and Treatment
Treatment for paresthesia is selected by a doctor or professional in the neurology area (neurologist), or other qualified source. A CT scan is commonly used for diagnosis. Once the diagnosis has been made, treatment options may include medication, moving limbs, and loosening or actively using muscles.
Underlying causes may lead to different treatment methods, especially related to those particular conditions. Please keep in mind that there is no cure for some of the causes of this sensation, although there may still be treatment or management options. Additionally, relief for the symptoms may be desired, so some treatment options may be requested that are mainly, or even purely, symptomatic ones.
