Paresthesia, tingling and neuropathies

Paresthesias are abnormal sensations such as tingling, numbness, pins and needles or a part of the body falling asleep. They are a very common symptom, often with benign causes that nonetheless need to be identified.

The most common causes

  • Carpal tunnel syndrome: tingling in the first fingers of the hand, often at night.
  • Ulnar nerve compression at the elbow: tingling in the fourth and fifth fingers.
  • Radiculopathies: compression of the nerve roots in the neck or lower back, with symptoms along an arm or a leg.
  • Polyneuropathies: symmetrical tingling in the feet and hands, for example in diabetes, vitamin B12 deficiency, alcohol abuse or with some medicines.
  • Central causes: rarer, such as multiple sclerosis or stroke.

Diagnosis

The distribution of symptoms already points strongly towards the diagnosis. Electromyography with nerve conduction studies confirms nerve involvement, measures its severity and distinguishes the different forms. Blood tests and, when indicated, MRI complete the assessment.

Sudden tingling on one side of the body, especially with weakness or difficulty speaking, requires urgent assessment instead.
