Tingling is a sensation that is commonly described as a feeling of “pins and needles” or a “creepy-crawly” sensation. It is often felt in the hands, feet, or other parts of the body, and is usually caused by nerve compression or damage. Some common causes of tingling include poor circulation, nerve compression due to injury or repetitive motion, vitamin deficiencies, and certain medical conditions such as diabetes or multiple sclerosis. Treatment for tingling depends on the underlying cause, and may include physical therapy, medication, or surgery in some cases. If tingling is accompanied by other symptoms such as weakness or loss of sensation, it is important to seek medical attention promptly.
