What is tingling?
Tingling (paresthesia) is an unusual sensation most commonly felt in your hands, feet, arms and legs. Tingling is often associated with numbness, or a decrease in the ability to feel or sense pressure or texture.
Tingling can be associated with a wide variety of conditions, including prolonged pressure on a nerve, vitamin or mineral deficiencies, multiple sclerosis (disease that affects the brain and spinal cord, causing weakness, coordination and balance difficulties, and other problems), and stroke, among many others.
Tingling can be mild and result from simple pressure on a nerve, such as when your foot or leg falls asleep when you are seated in the same position for a long time. Tingling can also be a symptom of more serious permanent nerve damage or underlying disease. Therefore, it is important to identify the cause of any unexplained or unusual tingling.
Seek immediate medical care (call 911) if you, or someone you are with, experience serious symptoms, such as the sudden onset of unexplained tingling; weakness or numbness on just one side of your body; sudden severe headache; sudden loss of vision or vision changes; changes in speech such as garbled or slurred speech; or the onset of tingling following a head, neck or back injury.
If your tingling is persistent, unexplained, or causes you concern, seek prompt medical care.
