... following a gall bladder operation. She had the op yesterday, and has been unable to have a wee since then. She's had a scan and has a full bladder, but nothing happens when she sits on the loo. She's tried running taps and pouring water on herself, but it hasn't helped. They don't want to catheterise her because of her age (?) (she's about 26). She feels like she's desperate to go to the loo, and is in pain because of it, and not drinking because she doesn't want it to get any worse.
Any ideas gratefully received!
