Carpal tunnel syndrome occurs when swelling or inflammation exists inside the carpal tunnel passageway that runs through the wrist. This passageway is very narrow and filled with the median nerve and the tendons that work the fingers and thumb. Because there is such a limited amount of space in the carpal tunnel passageway, any swelling causes these structures to be compressed. Continued compression may lead to permanent nerve damage if not treated.
Tingling of the Skin on the Fingers
Tingling from carpal tunnel often begins along the thumb side of the hand. The tingling may also be described as a crawling, as if there were tiny bugs moving along the skin. This creeping can range from a light coming and going to a strong constant irritation. Tingling usually begins irregularly and progresses to constant.
Numbness of the Finger Tips
Numbness associated with carpal tunnel is often described as a lack of sensation. With this lack also comes a decreased ability to grab or keep a hold of objects. This numbness may also feel like pressure or as if the hand is swollen to larger than its normal size. It can be one of the more bothersome symptoms because lack of feeling can lead to more injury due to the interference with hot and cold sensitivity.
Pins and Needles Sensations
The description is exactly how the sensation feels. Pins and needles can be characterized as a "falling asleep" of the wrist and hand. It may be confined to the hand; it may also travel up the arm towards the elbow. Just like the tingling, the pins and needles sensation may begin slowly and grow steadier with time.
Pain in the Hand
The pain coupled with this syndrome can come in many different forms. A dull ache is commonly reported, but sharp, stabbing, throbbing, and pinching may also be used to describe the pain.
Oftentimes, the pain is worse at night. The position of the hand and arm during sleep can increase the carpal tunnel symptoms. Many people sleep with wrists flexed or arms above the head, which can impede the flow of blood and reduce circulation. Blood, which nourishes the hand and helps promote healing, is needed to counter the strain that is put on the hands during everyday life.
Any of these symptoms may happen alone, but they may also occur together. If these symptoms are noticeable after doing something repetitive like working with lawn equipment or a typing at a keyboard, then a trip to a doctor's office for a few tests may be in order. Early detection and treatment of carpal tunnel can prevent a recurrence of the syndrome.
