Why do my Fingers Go Numb?
Finger Numbness is usually a result of damages and/or diseases to the nerves in your fingers, hands, wrists, arms and even in your neck. Damages to the nerves in your fingers may have been from an accident or trauma to the nerves in your hands. When compared to a RSI (repetitive strain injury), an accident at work that may have crushed or broken your fingers and damaged the nerves is easier to diagnose as the root cause.
Repetitive strain injuries to your fingers that can cause nerve damages are actions like typing, keyboarding, mousing, handling machinery that vibrates (like a power saw, a jackhammer or rototiller), and yes… even text messaging on your “blackberry” phone. Inflammation of the tendons, tendon sheaths and the ligament of your fingers and thumbs can easily be treated with Far Infrared Rays.
Who Gets Finger Numbness?
Finger Numbness is very common during pregnancy. Some women experience fluid retention which can cause swelling at the joints and, at the knees and wrists. When the wrist swells, there is pressure on the Median Nerve which can reduce circulation to the fingers.
Numbness and tingling are more serious when:
- You have a cut or puncture wound that may have cut a nerve.
- You have a complete loss of feeling.
- You have symptoms of decreased blood flow, such as pale, white, blue, or cold skin.
- You have muscle weakness not caused by pain.
- Symptoms don’t go away.
- Symptoms go away, but keep coming back.
Hyper Reaction Turn Fingers White, Blue & Red
You open the fridge and grab something cold with your bare hand. Bang! It triggers a Raynaud’s attack. The blood vessels in your fingers spasm and contract wildly, seriously constricting blood flow to your hands. Your fingers or fingertips turn white. So, what causes this to happen? Your body’s natural defense mechanism has just hyper reacted to touching something cold! Its purpose is to preserve your core body temperature and protect your vital organs (in an emergency situation) by drawing blood away from the extremities and surface of the skin deeper into the body. In the case of Raynaud’s attacks, it appears to be a hypersensitive overreaction to change in temperature or even emotional stress.
As blood supply begins to return to your fingers, it can still be low in oxygen, making the skin appear blue or discolored. Blue fingers are caused by the temporary lack of oxygenated blood flow to the tips of your fingers.
A sudden rush of fresh oxygenated blood returning to your hands brings on a lot more than just the red flush color. Nerve endings burn with pain, as the numbness and tingling feeling retreats. If you’re a victim of Raynaud’s syndrome, you know exactly what I’m talking about. So, what’s my point?
Every time you experience a Raynaud’s attack, blood flow and oxygen supply is seriously restricted from reaching the tiny capillaries and blood vessels in your hands. Frequent attacks can result in accumulative damageto your microcirculatory system. In other words, the more attacks you have, the more likely they are to occur again. It becomes a vicious cycle!
Carpal Tunnel Syndrome (CTS); See the separate Article on this Blog
it’s the result of overworking your hands – performing repetitive (motion) task all day long.
Eventually, the stress and strain of constantly doing the same thing with your hands causes the tendons that run through the carpal tunnel , from your wrist into your hand, to become swollen. Swelling of tendons (swollen tenosynovium) from overuse puts pressure on the median nerve, resulting in tingling and numbness in your thumb, index and middle fingers.
That’s what I mean about losing your grip. If you have difficulty simply holding a cup of coffee in the morning or your hands ache (like you know what) when trying to put the keys in the door or even hold a newspaper, then you need to try Prolotex Far Infrared Therapy Gloves and Wristbands.
