Pins and needles is a pricking, burning, tingling or numbing sensation that is most commonly felt in the arms, legs, hands or feet. It does not usually cause any pain, but it can cause numbness or itching. . A common cause is awkward postures that compress the nerves. Tingling sensations can also be symptomatic of nerve damage or nervous system disorders. The feeling of pins and needles is known as paresthesia. Most people associate it with sleeping incorrectly on a nerve. This causes the nerve to stop sending signals so that it falls asleep and creates a feeling of numbness. When pressure is taken off of the nerve, the body sends shock waves down the nerve to wake it up. This is what creates a feeling of pins and needles. But paresthesia doesn t just occur when a nerve has pressure. It may also occur during anxiety, especially during panic attacks. That s because during panic attacks, the body becomes more prone to hyperventilation. During hyperventilation, the body has too much oxygen and not enough carbon dioxide. That imbalance causes every vessel inside the body to constrict, while simultaneously reducing the release of calcium into the nerves. Both of these cause the nerves to feel tingly. Some vitamin deficiencies, such as low levels of magnesium, Vitamin B12, and vitamin B5 can also cause a tingling feeling and contribute to anxiety sensations .
