With anxiety, it's due to hyperstimulation, and it's caused by the stress response. The nerve endings become overstimulated and send the wrong info to the brain.
If you've been highly anxious for a while - I'd suggest that this is the most likely cause, but it's my policy to have all new (and lingering) symptoms checked by my GP.
