Numbness or Tingling in the Hands or Fingers
Numbness or Tingling in the Hands or Fingers
Anything that reduces the blood supply to the wrists, hands and fingers can cause nerve damage, and this damage creates the feeling of numbness or tingling in that area of the body.
A variety of activities and conditions can contribute to this reduced blood supply. Sometimes repetitive motions over a long period of time, such as in a work, hobby or sports setting, can be a factor. Diabetes can reduce the blood supply to peripheral areas of the body, resulting in nerve damage. Arthritis and Multiple Sclerosis can also cause this condition, as can certain chemotherapy drugs used for cancer treatment.
Some of the most common conditions causing numbness or tingling are:
Tendonitis
Tendonitis is an inflammation of a tendon in the body. Tendons attach muscles to bones, and are responsible for helping to create movement. Normally tendons glide smoothly, but when they become inflamed, this process is affected. Stiffness, pain, and sometimes tingling is noticeable. Sports or other injuries can cause this sudden inflammation, but so can repetitive motions from working on a computer, repetitive manufacturing jobs, sewing, playing a guitar or other activities.
Carpal Tunnel Syndrome
The carpal tunnel is a narrow passage through the wrist that houses and protects the median nerve, running from the hands all the way up the arm. When this tunnel becomes inflamed, pressure is placed on this nerve and pain, numbness and tingling can occur. Some people are genetically more prone to this condition; others can develop it over time from repetitive motions involving the wrists and fingers.
Trigger Finger or Trigger Thumb
Again caused by inflammation, in this case the tendons in the fingers, this condition causes a finger or the thumb to become “stuck” in a bent position, and then to snap back when it releases, much like a trigger releasing. Early signs of trigger finger can include stiffness when you move the finger, your joint “popping” when you move it, or a bump at the base of the finger. Repetitive grasping or gripping motions are usually the source of this condition. If not treated properly, the digit can become permanently bent.
The most important step to take when you are experiencing numbness or tingling in the hands is to start with a proper diagnosis of the cause of the condition. It is best to consult a doctor who specializes in treating the hands and the upper body, as these are delicate structures involving complicated interactions between the tendons, ligaments, nerves, bones and muscles.
Most causes of tingling and numbness can be treated with a variety of non-invasive techniques, and will successfully resolve with proper treatment and time. Sometimes a surgical intervention is necessary, and in this case you definitely want a hand surgeon; an orthopedic doctor with specialization in the hands, wrists and upper body.
