My daughter is nearly ten and been complaining of tummy pains for the past couple of weeks. There is no temperature, vomitting or diorrhea. She is not going to the toilet regularly and complains that when she does go it hurts or feels like she wants to go, then when she gets to the loo, the sensation stops. She has been prescribed buscopan, first, then movicol, which we had to stop after three days as she was going to the toilet too much and it was diorrhea. Today she went for an ultrasound on her abdomen and some red colour showed up on the screen during the scan. What does this mean?
