Was admitted Sunday night due to passing a gallstone. Spent yesterday in hospital awaiting a scan and nil by mouth from 7.30am til 5pm and finally released last night. I was on a saline drip the whole time so can't be dehydrated can I? This morning, just had scary wee - almost luminescent bright yellow wee. I was thinking dehydration at first or drugs that I was given. Only had oral morphine and some paracetamol though. I did give them a urine sample earlier in the day and it was fine yesterday morning so they'd have picked up anything unusual wouldn't they? Any ideas!?
