Although many individuals normally regard numbness in fingers as a mild condition, the truth is that it could represent any of several more significant clinical conditions, some of which can bring about long-term nerve or tissue damages. Finger sensitivity plays a large function in how we communicate with the world around us. While numbness in fingers may not appear like the most urgent medical condition, you might want to think about how the fingers' thermoreceptors contribute to your everyday activity, as well as survival: the capacity to properly translate the temperature level of something informs you if it's too hot, too cold, and if that temperature level is capable of actually harming your body. If numbness in fingers is keeping your fingers from accurately relaying these communications to your brain, the results could be harmful and even dangerous.
Discomfort, Tingling and Numbness in Fingers
People who experience numbness in fingers also report the feeling of tingling in the fingers as well, which can be a strong indication of impending nerve damage. As with a multitude of serious hand and arm conditions, the source is most likely stress or excess pressure affecting the nerve, which can lead to less sensation, or the emission of pain signals due to the distress. Below are a few of the usual conditions that could be responsible for either numb fingers, or damaged nerves in the hand and arm:
Causes of Numbness in Fingers
- Carpal Tunnel Syndrome: Numbness in fingers is one of the most telltale carpal tunnel syndrome symptoms and is practiced in practice every person affected with CTS. Due to overuse of the hand, the tissue inside the wrist will begin to expand from stress, which enforces pressure on the nearby nerve. As the pressure increases, the median nerve sufferers from greater damage, which often leads to the “pins and needles” sensation that many patients report in the hand or fingers. If the pressure persists, the nerve could suffer long-term damage.
- Cubital Tunnel Syndrome: In the elbow, the ulnar nerve may be taken in an uneasy position, which imposes excess pressure on the nerve, continuing to reduce the arm's sensation as it moves away from the elbow. However, instead of just having an effect on the elbow, Cubital Tunnel Syndrome can trigger discomfort in the lower arm and hand as well. Cubital Tunnel Syndrome can restrict finger motion, and can force fingers into an awkward position. Also referred to as “Ulnar Nerve Entrapment”, this condition must not go without adequate medical attention.
- Poor Blood Circulation: Poor blood flow can be the output of numerous conditions, not the least of which is peripheral artery disease in which the blood vessels to the arms and legs begin to narrow and subsequently prevent healthy blood flow to the fingers and toes. Decreased blood flow does not just lower sensitivity, but can also limit the amount of nutrients and oxygen that your body gets. A condition called Raynaud's Phenomenon might likewise the root cause where the capillary in the fingers and toes begin to narrow, causing numbness in fingers and sensations that are extremely similar to carpal tunnel symptoms. An additional potential cause, Dupuytren's Contracture, is a tissue disease which curls fingers into a bent position due to hardened tissue benefit the skin. The rigid, diseased tissue forces the fingertips into the palm of the hand, a position that is not ideal for correct blood flow. Dupuytren's Contracture can also be treated with hand surgery, so be sure to seek advice from a qualified hand surgeon if you suspect you are suffering from the disease.
