Ive experienced it in my left hand. What ive found that works is not only changing my position but gripping the tank tighter with my legs.

Is Madd on to something here! By gripping the tank tighter..he is relieving downward pressure on the grips. Ideally you are riding with arms slightly bent , mimimal downward pressure on the grips..light grip vs. the death grip.....
