What Causes Pins And Needles?

Hyperventilation

Hyperventilation occurs when an individual breathes very rapidly. During hyperventilation, the individual will breathe out more than they breathe in, and this quickly reduces the amount of carbon dioxide in the body. When carbon dioxide levels are too low, symptoms such as pins and needles in the hands and fingers and lightheadedness may occur. Some patients may faint if hyperventilation is severe. Hyperventilation typically occurs as a result of fear, phobias, or highly stressful situations. It may also develop in response to anger or sadness. Severe pain, head injuries, bleeding, stimulant use, and lung infections are other recognized causes. Patients with hyperventilation may experience symptoms for twenty to thirty minutes, and chest pain and a rapid heartbeat could be present. Since hyperventilation mimics the symptoms of serious medical conditions, it is important to see a doctor, particularly if the patient experiences frequent hyperventilation or if it is accompanied by chest pain. Treatment for hyperventilation focuses on changing the patient's breathing technique. Patients may be able to self-treat hyperventilation by breathing into a paper bag or cupped hands, and holding the breath for ten to fifteen seconds might be beneficial as well. Stress reduction measures are recommended, and patients may need to take medications like alprazolam to reduce anxiety.

Stroke

A stroke is a medical emergency in which the blood flow to the brain is interrupted. Patients having a stroke frequently experience sudden weakness, numbness, or paralysis in the face or a limb. These symptoms typically occur on one side of the body. For example, one side of the face may be affected, or the patient might notice symptoms in their right arm or leg even though the left leg is able to function normally. Patients could also have double vision or vision loss in one or both eyes, and blurry vision is common. Severe headaches may develop suddenly, and these might be accompanied by vomiting, dizziness, or confusion. Patients might have trouble speaking or understanding others, and loss of balance may be present. To diagnose a stroke, doctors at the hospital will perform a brain scan, and patients will also have blood tests. A neurological exam will be conducted, and an echocardiogram, carotid ultrasound, or cerebral angiogram may be indicated in certain situations. Treatment for a stroke depends on the type of stroke the patient has had. If an ischemic stroke is diagnosed, the patient may be able to have intravenous medication to break down blood clots, and doctors might perform endovascular procedures. Surgical procedures are also used to treat hemorrhagic strokes. After recovering from a stroke, the patient will likely need to go to a rehabilitation center for physical and occupational therapy before returning home.
