Suggest Treatment For Fatigue After A Back Injury

Hello about te n minutes ago i had a fall from a step ladder onto my back, luckily the snow cushioned the fall but i have bruised my right upper buttock and balower back and jerked my neck, and now i feel sick and tired and i have also wept??? (delayed shock perhaps) I've taken paracetamol and feleel like lying down a while but my partner says I shouldn't...can you advise?
