RSI is a progressive condition, it starts with mild pain or tiredness of the
hands, arms etc. during the working day, getting better overnight. Progressing
to the pain and tiredness persisting overnight, but getting better after a few
days break, to finally persistent pain which does not go away even after
complete rest.

The earlier treatment is commenced, the better your chance of complete
recovery.  In the later stages, complete recovery is not always possible
although symptoms can be reduced with treatment.
