Like others told, you shoud rest.
But when you will start again to practise, dont practise first day so much, take just one hour, have long braek, like 3 hours and than again one more hour, second day practise half hour more, 3rd day half more and.... and ofcourse practise only slowly, just after some time start to practise normal, and use exersize befor you start practise peases.
If you will start to fell, that hands hurt again, just little bit, stop and relax.
