The skin's way of filing a complaint about repetitive motion.

means To wear, irritate, or rub raw through repeated friction — or, figuratively, to feel irritated and restless under some constraint.

from From Old French 'chaufer,' meaning to warm or heat, which traces back to Latin 'calefacere' — 'calere' (to be hot) plus 'facere' (to make). The sense shifted from 'to heat by rubbing' to simply 'to rub' to 'to irritate by rubbing,' the friction's warmth giving way to its wear-and-tear. The same Latin root, incidentally, gave us 'cauldron' and 'calorie' — all children of heat.
