Paresthesia is an abnormal sensation of the skin (tingling, pricking, chilling, burning,
The most familiar kind of paresthesia is the sensation known as "pins and needles" after having a limb "fall asleep". A less well-known and uncommon paresthesia is formication, the sensation of insects crawling on the skin.
Causes
Transient
Paresthesias of the hands, feet, legs, and arms are common transient symptoms. The briefest electric shock type of paresthesia can be caused by tweaking the ulnar nerve near the elbow; this phenomenon is colloquially known as bumping one's "funny bone". Similar brief shocks can be experienced when any other nerve is tweaked (e.g. a pinched neck nerve may cause a brief shock-like paresthesia toward the scalp). In the older age group, spinal column irregularities may tweak the spinal cord briefly when the head or back is turned, flexed, or extended into brief uncommon positions (Lhermitte's sign).[citation needed]
The most common everyday cause is temporary restriction of nerve impulses to an area of nerves, commonly caused by leaning or resting on parts of the body such as the legs (often followed by a pins and needles tingling sensation). Other causes include conditions such as hyperventilation syndrome and panic attacks. A cold sore outside the mouth (not a canker sore inside the mouth) can be preceded by tingling due to activity of the causative herpes simplex virus. The varicella zoster virus (shingles) also notably may cause recurring pain and tingling in skin or tissue along the distribution path of that nerve (most commonly in the skin, along a dermatome pattern, but sometimes feeling like a headache, chest or abdominal pain, or pelvic pain).[citation needed]
Other common examples occur when sustained pressure has been applied over a

Irritation to the nerve can also come from inflammation to the tissue. Joint conditions such as rheumatoid arthritis, psoriatic arthritis, and carpal tunnel syndrome are common sources of paresthesia. Nerves below the head may be compressed where chronic neck and spine problems exist, and can be caused by, among other things, muscle cramps that may be a result of clinical anxiety or excessive mental stress,[citation needed] bone disease, poor posture, unsafe heavy lifting practices, or physical trauma such as whiplash. Paresthesia can also be caused simply by putting pressure on a nerve by applying weight (or pressure) to the limb for extended periods of time.[citation needed]
Another cause of paresthesia may be direct damage to the nerves themselves, i.e.,
The varicella zoster virus disease (shingles) can attack nerves, causing numbness instead of the pain commonly associated with shingles.[citation needed]
Acroparesthesia
Acroparesthesia is severe pain in the extremities, and may be caused by Fabry disease, a type of sphingolipidosis.[15]
It can also be a sign of hypocalcemia.[16]
Dentistry
Dental paresthesia is loss of sensation caused by maxillary or mandibular anesthetic administration before dental treatment.[17]
Potential causes include trauma introduced to the nerve sheath during administration of the injection, hemorrhage about the sheath, more side-effect-prone types of anesthetic being used, or administration of anesthetic contaminated with alcohol or sterilizing solutions.[18]

In addition to treatment of the underlying disorder, palliative care can include the use of topical numbing creams, such as lidocaine or prilocaine. Ketamine has also been successfully used, but is generally not approved by insurance. Careful consideration must be taken to apply only the necessary amount, as excess can contribute to these conditions. Otherwise, these products generally offer extremely effective, but short-lasting relief from these conditions.
Paresthesia caused by stroke may receive some temporary benefit from high doses of baclofen multiple times a day.[citation needed] HIV patients who self-medicate with cannabis report that it reduces their symptoms.[23]

Etymology
The word paresthesia (/ˌpærɪsˈθiːziə, -ʒə/; British English paraesthesia; plural paraesthesiae /-zii/ or paraesthesias) comes from the Greek para ("beside", i.e., abnormal) and aisthesia ("sensation").[25]

Paresthesia refers to a burning or prickling sensation that is usually felt in the hands, arms, legs, or feet, but can also occur in other parts of the body. The sensation, which happens without warning, is usually painless and described as tingling or numbness, skin crawling, or itching.
Most people have experienced temporary paresthesia -- a feeling of "pins and needles" -- at some time in their lives when they have sat with legs crossed for too long, or fallen asleep with an arm crooked under their head. It happens when sustained pressure is placed on a nerve. The feeling quickly goes away once the pressure is relieved.
Chronic paresthesia is often a symptom of an underlying neurological disease or traumatic nerve damage. Paresthesia can be caused by disorders affecting the central nervous system, such as stroke and transient ischemic attacks (mini-strokes), multiple sclerosis, transverse myelitis, and encephalitis. A tumor or vascular lesion pressed up against the brain or spinal cord can also cause paresthesia. Nerve entrapment syndromes, such as carpal tunnel syndrome, can damage peripheral nerves and cause paresthesia accompanied by pain. Diagnostic evaluation is based on determining the underlying condition causing the paresthetic sensations. An individual's medical history, physical examination, and laboratory tests are essential for the diagnosis. Physicians may order additional tests depending on the suspected cause of the paresthesia.
