What is finger paresthesia?
Finger paresthesia is an abnormal condition in which you feel a sensation of burning, numbness, tingling, itching, or prickling, sometimes described as pins and needles, in one or more fingers in the absence of stimuli. Finger paresthesia may or may not be accompanied by pain.
The duration and course of finger paresthesia varies widely, depending on the underlying cause. Paresthesia caused by holding your arm in the same position for a long period of time often has a sudden onset. This is commonly referred to as your arm “being asleep.” Most people experience this type of sensation at one time or another, and it normally fades away quickly once you move your arm. In other cases, finger paresthesia sensations develop slowly and persist or worsen over time.
Finger paresthesia can arise from a lack of blood supply to an area or damage to a nerve or nerves that supply the hand and fingers. This can be due to such conditions as carpal tunnel syndrome or a cervical disk problem. Finger paresthesia can also result from infection, inflammation, medications, trauma, and other abnormal processes. Finger paresthesia is rarely due to a life-threatening disorder, but it can arise from a stroke or tumor. Chronic finger paresthesia or intermittent finger paresthesia occurring over a long period of time is generally a sign of a neurological disease or nerve damage.
Depending on the cause, finger paresthesia may be present in only one finger or even a small part of a finger, such as the nail or fingertip, or it may be present in all fingers on both hands. For example, ulnar nerve compression in the arm may cause paresthesia of the pinky and ring fingers. Carpal tunnel syndrome may bring about paresthesia of the thumb, index, middle, and half of the ring finger.
Finger paresthesia can be a symptom of a serious disease, disorder or condition. Seek prompt medical care for any unusual finger sensations that last more than a few minutes, recur, or cause you concern.
Seek immediate medical care(call 911) if you have paresthesia in the fingers along with loss of bladder or bowel control, paralysis, sudden confusion, weakness in the extremities, or slurred speech.
