proudmom9901,
You have the early signs of carpal tunnel syndrome (CTS). Night waking or waking up with numbness, tingling, and/or pain in the hand(s) is one of the hallmarks of CTS.
The median nerve (which supplies sensation to the palmar thumb, index finger, middle finger, and half of the ring finger) runs through the carpal tunnel at the base of the palm. The space in this tunnel is very tight, as along with the nerve, nine tendons also go through it. The nerve can be compressed when the wrist is flexed. A very common position for humans to get into when sleeping is to draw our hands up under our chins. In doing this, the wrists are often flexed down. We also, sometimes, support our chin or forehead with the base of the palm, resting that way. This can also compress the nerve. The result is for the nerve to go to sleep. This causes the numbness, tingling, and pain. Nerve pain is a deep aching discomfort.
The reason that CTS patients are told to wear splints at night, is to just keep the wrists out of these positions, nothing else.
Other things that can cause the symptoms of CTS are continuous grasping (holding the phone for a long period, clutching the steering wheel while driving, holding the mouse for a long period), intermittent strong grasping (as in using pliers or wrenches at work), or the use of vibrating equipment on the job.
It is a very common misconception that the use of a computer keyboard causes CTS. It does not. However, if the person has his/her wrists in improper positions while trying to type, that can cause CTS symptoms. If the wrists are too high or too low, causing extreme flexion or extension, the median nerve can be compressed, along with a whole host of other problems with the shoulders, neck and back.
So, it sounds like you have the beginnings of CTS. The first thing that is tried is a small, basic wrist splint for night wear (not too tight). Some people do well with Vitamin B6, others it does not help at all. Maintain wrist range of motion, because stiffness in the wrist often makes CTS worse.
But, if your symptoms continue or get worse, you might want to see your physician. Good luck.
