You're doing it the wrong way. You pinch, but not THAT hard. Pinch with your thumbs on top of the markers and the other four fingers on the bottom. Pull the bottom upwards in a somewhat circular motion TOWARDS YOU while pushing downward on top AWAY FROM YOU. This will remove them very easily without hurting your hands.
