Can anxiety cause pins and needles all over the body?

When you're anxious, your body can go into a stress mode. This can make you breathe faster (a process called hyperventilation), which may lower the level of carbon dioxide in your blood. Changes like these can cause the nerves in your arms, legs, or other parts of your body to send odd signals that feel like tiny pins and needles. This sensation is sometimes called paresthesia. In addition, anxiety might also make you more aware of normal body sensations, so even regular feelings can seem stronger or unusual when you're stressed. Many people experience these tingling sensations during periods of high anxiety, and while they can be uncomfortable or startling, they are often not harmful. However, if the pins and needles feeling becomes very frequent, lasts a long time, or comes with other symptoms such as weakness or chest pain, it's a good idea to speak with a healthcare provider.
