What Causes Pins And Needles?

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.
