DS (2.9) has been diagnosed with a UTI and is having terribly painful wees. He holds on until he cant hold it any longer and then screams and cries while going. He has to go standing up and running/hopping on the spot, can't sit on the potty. This evening i managed to hold his hands away while he went in the bath and saw his whole penis balloon to more than twice its width while he was weeing. I'd noticed it was looking swollen and discoloured and thought it might be caused by the infection, or bruised from being clutched when he's trying not to go, but now I'm worried about blockages. This is the third day of antibiotics with no improvement, lab results from Monday not back yet, and we've just been given new antibiotics as the original ones weren't working, but if its a physical bit of damage presumably the new ones won't work either... Anyone had experience or know what this is please?
