Numbness in the fingers can develop as a result of any number of factors, and you should not simply assume that it is a sign of carpal tunnel syndrome, unless you have good reason to do so. Carpal tunnel syndrome is basically a condition in which the median nerve, which runs through a canal in the wrist, gets compressed. As a result, the person starts to experience numbness and weakness in the hand, along with a tingling, burning sensation. Even here, a variety of factors can be at play - forceful and repetitive use of the hands, such as that associated with computer use, is often blamed for carpal tunnel syndrome, but a clear and indisputable link between the two has not yet been established. In most cases, carpal tunnel syndrome is described as idiopathic - which means that it has no known cause. In fact, carpal tunnel syndrome is often thought to be genetic.
Proper diagnosis of numbness and pain in the hands is quite difficult - very often carpal tunnel syndrome is misdiagnosed, and at the same time other conditions are misdiagnosed as carpal tunnel syndrome. Pain is not an important symptom of carpal tunnel syndrome, and therefore, if you have been experiencing a lot of pain, you can probably rule out this condition. Numbness and tingling are the main symptoms of carpal tunnel syndrome. In any case, you need not worry about surgery yet. The simplest and most effective treatment in many cases is a wrist splint - a contraption that keeps the wrist straight, particularly at night. Most people tend to bend their wrists when they sleep, and this compresses the median nerve further. Wrist splints prevent this compression, and are therefore an important part of managing carpal tunnel syndrome. For the same reason, you should also analyze your movements, especially repetitive tasks, such as typing, or any other work you may do with your hands. The position of your hands during these activities may be a contributing factor that can be eliminated.
It is however advisable that you consult a doctor before taking any action. A proper diagnosis will save time and allow you to treat your condition promptly and more effectively. Diabetic neuropathy, alcoholic neuropathy, and a variety of conditions involving nerve damage can cause numbness and pain in the hands. You might end up wasting time on the wrong treatment if you attempt to handle the problem yourself.
