DS has had soiling issues for a while. We saw the GP, who prescribed one sachet of movicol a day and to come back in a month. It got no better. GP suspects impaction. He had to have 4 sachets the first day, then increase by two a day until he passed the blockage, then back down to two sachets maintenance level. We go back in a fortnight. DS has had two large BM, but they were soft. Since then, he has been (sorry) pooing ribbons of very soft stool, or out and out diarrhoea. Tomorrow, he'll be on the maximum dose of 12 sachets. He says he still feels blocked up. Has anyone else dealt with this in their child? Will I definitely know that the blockage has gone? He still has tummy pains, feels a bit sick etc.
