It sounds to me like you have inflamed the tendons on the wrist by leaning on it and bending it under pressure for a long period of time. Any discolouration anywhere on the hand?
And you can move your fingers yes.
I'm not a Dr and this ain't medical advice, but I would ice the area for a bit, maybe support it in a sling for a day or so and allow any swelling that has occurred to go down. The symptoms do sound like tendonitis, read more here.
