causes of tingling in body
Numbness and tingling are unusual prickling sensations that can happen in any part of your body. People generally notice these sensations in hands, feet, arms, and legs. Many things can cause numbness and tingling, including sitting with your legs crossed or falling asleep on your arm.
The most common reason for numbness or tingling is a problem with nerve function, either because the nerve itself is injured, something is pressing on the nerve, or an imbalance in the body's chemistry interferes with nerve function.
Sometimes a specific injury can produce numbness or tingling, such as an injured nerve in your neck or a herniated disk in your spine. Placing pressure on a nerve is a common cause. Carpal tunnel syndrome, scar tissue, enlarged blood vessels, infection, or a tumor can all place pressure on a nerve.
