Paresthesia is an abnormal sensation of the skin (tingling, pricking, chilling, burning, numbness) with no apparent physical cause.[1][2] Paresthesia may be transient or chronic, and may have any of dozens of possible underlying causes.[1] Paresthesias are usually painless and can occur anywhere on the body, but most commonly occur in the arms and legs.[1]

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 but important 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 (a tweaked 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 because a cold sore is caused by 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 nerve, inhibiting or stimulating its function. Removing the pressure typically results in gradual relief of these paresthesias.[3] Most pressure-induced paraesthesia results from awkward posture, such as engaging in cross-legged sitting for prolonged periods of time.[citation needed]

Reactive hyperaemia, which occurs when blood flow is restored after a period of ischemia, such as on rewarming after a cold episode in patients with Raynaud's disease, may be accompanied by paresthesia.[4]

Chronic

Chronic paresthesia (Berger's paresthesia,[5] Sinagesia[6] or Bernhardt paresthesia)[7] indicates a problem with the functioning of neurons or poor circulation.[citation needed]

In older individuals, paresthesia is often the result of poor circulation in the limbs (such as in peripheral vascular disease), most often caused by atherosclerosis, the build up of plaque within artery walls, over decades, with eventual plaque ruptures, internal clots over the ruptures and subsequent clot healing but leaving behind narrowing of the artery openings or closure, both locally and in downstream smaller branches. Without a proper supply of blood and nutrients, nerve cells can no longer adequately send signals to the brain. Because of this, paresthesia can also be a symptom of vitamin deficiency and malnutrition, as well as metabolic disorders like diabetes, hypothyroidism, and hypoparathyroidism. It can also be a symptom of mercury poisoning.[citation needed]

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., neuropathy, which itself can stem from injury, such as frostbite, or infection, such as Lyme disease, or may be indicative of a current neurological disorder. Neuropathy is also a side effect of some chemotherapies, such as in chemotherapy-induced peripheral neuropathy.[8] Benzodiazepine withdrawal may also cause paresthesia as the drug removal leaves the GABA receptors stripped bare and possibly malformed.[citation needed] Chronic paresthesia can sometimes be symptomatic of serious conditions, such as a transient ischemic attack, or autoimmune diseases such as multiple sclerosis, Complex Regional Pain Syndrome or lupus erythematosus.[citation needed] The use of fluoroquinolones can also cause paresthesia.[9] Stroke survivors and those with traumatic brain injury (TBI) may experience paresthesia from damage to the central nervous system.[citation needed]

The varicella zoster virus disease (shingles) can attack nerves causing numbness instead of 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.[10]

It can also be a sign of hypocalcemia.[citation needed]

Dentistry

Paresthesia or "persistent anesthesia" is a transient or potentially permanent condition of extended numbness after administration of local anesthesia and the injected anesthetic has terminated.[11]

Potential causes include trauma introduced to the nerve sheath during administration of the injection, hemorrhage about the sheath, type of anesthetic used, or administration of anesthetic potentially contaminated with alcohol or sterilizing solutions.[12]

Other

Other causes may include:

Diagnostic

The nerve conduction study usually provides useful information for making diagnosis. A MRI or a CT scan is sometimes used to rule out some causes from the central nervous system.[citation needed]

Treatment

Medications offered can include the immunosuppressant prednisone, intravenous gamma globulin (IVIG), anticonvulsants such as gabapentin or Gabitril and antiviral medication, depending on the underlying cause.[medical citation needed]

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 still not approved indications by insurance. Careful consideration must be taken to apply only the necessary amount, as excess can contribute to conditions. Otherwise, these products offer extremely effective, but short-lasting, relief from the condition. 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.[17]

Paresthesia caused by shingles is treated with appropriate antiviral medication.[18]

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").[2]
