London: Temporary numbness and tingling can occur after spending too much time sitting cross-legged, or with a head resting on a crooked arm. But long term, severe, or disabling numbness and tingling is usually a sign of neurological conditions or nerve damage.
This article focuses on common causes and treatments for numbness and tingling, including multiple sclerosis (MS). These sensations commonly occur after sitting or standing in a particular position or even wearing tight clothing for too long. This puts pressure on nerves and blood vessels, reducing sensation.
Numbness and Tingling in Hands and Feet
Symptoms usually go away soon after the nerve pressure is reduced or relieved.
Numbness and tingling are two of the most common and early symptoms of MS. MS often causes mild to severe numbness and tingling on the skin or certain parts of the body, including the: arms and hands, legs, and feet face, body, often across the body in a band (sometimes described as an MS hug).
The numbness and tingling symptoms of MS are rarely disabling or permanent. But severe numbness can make it difficult for a person to use the numb body part, which may interfere with everyday activities.
For example, numb hands can make holding things, typing, or self-care hard or impossible. If someone has numb feet or legs, walking and driving can be dangerous. People with numbness and tingling in their faces may also mistakenly bite their tongue or inner mouth.
Severe numbness can make it hard to tell when things are very hot or cold, increasing the risk of burns and frostbite.
Feet and legs
People with diabetes may experience diabetic neuropathy, a type of nerve damage. It can occur over time as the metabolic effects of diabetes in the bloodstream damage nerves.
One-third to one-half of people with diabetes have peripheral neuropathy, a form that typically causes numbness and pain in the feet and legs, or less commonly, in the hands and arm.
