Yes it could very likely be carpal tunnel syndrome
There's a bony tunnel in the wrist through which runs a nerve
to the hand muscles and skin. This gets compressed in extreme positions of the wrist, like the one you use against your keyboard. If this occurs repetitively, it could cause pain, numbness
or even weakness of the outer 3 fingers.
Avoidance of this extremes of position would be helpful. In severe cases, the tunnel is surgically decompressed by cutting one of its walls.
