The question here isn't about damage but about what mechanisms in the "pain pathway" are responsible for OP's specific experience of this pain. One day he has sudden, debilitating pain - in both wrists - in the absence of a traumatic event. He's conspicuously omitted any kind of medical diagnosis, and the whole thing is part of an existential crisis on the tail end of an insane, psychologically unsustainable workload. Not a typical presentation of RSI, that's for sure.
