During a panic attack, the body's "fight or flight" response is triggered, leading to a surge of stress hormones like adrenaline and cortisol. This physiological response prepares the body to deal with perceived threats by increasing heart rate, dilating pupils, and redirecting blood flow to major muscle groups. The tingling sensation in your fingers (pins and needles sensation) during a panic attack can be attributed to this heightened physiological state and the way your body responds to stress.
Here's a more detailed explanation of why this might happen:
Hyperventilation: During a panic attack, you may unconsciously start to hyperventilate, which means you breathe rapidly and shallowly. Hyperventilation can lead to a decrease in carbon dioxide levels in the blood, which in turn can cause sensations like tingling or numbness in the extremities, including the fingers.
Vasoconstriction: The release of stress hormones can cause blood vessels to constrict in certain areas of the body, including the fingers and toes. This vasoconstriction reduces blood flow to the extremities, leading to the tingling or pins and needles sensation.
Sensory Disturbance: Anxiety and panic can affect the way the brain processes sensory information, leading to altered perceptions and sensations like tingling, numbness, or hypersensitivity.
Muscle Tension: During a panic attack, you may experience muscle tension and tightness throughout your body, including in your hands and fingers. This tension can compress nerves and blood vessels, leading to the sensation of pins and needles.
It's important to remember that while these sensations can be distressing, they are generally not harmful. Understanding that they are a natural part of the body's stress response during a panic attack can help you feel less anxious about them. However, if you are experiencing persistent or severe symptoms, it's essential to consult with a healthcare professional to rule out any underlying medical conditions and receive appropriate guidance and support for managing panic attacks and anxiety.
