DS (7) has been complaining of stomach pain - general ache, not sharp - for over a week now. I discovered he hadn't had a BM in three days, but did after I started heavy hydration with Gatorade and water, broth etc. It appeared he wasn't getting enough fluids at school and his desire for fluids seems decreased as well. He had been on antibiotics for a cough before that, but even tho I brought the doc a stool sample, they didn't test it, thinking he was dehydrated too. But we are still complaining of a belly ache, especially after drinking his Gatorade???!! I think. It's hard to know what's triggering it. The belly ache seems to come and go. He was on a probiotic while on antibiotics, but we quit taking it afterwards. He has had regular bowel movements the past four or 5 days, so I assume the constipation is done, Any suggestions??? Or ideas???. He did have a meconium ileus at birth, but no further complications since then. He was also recently dx with pseudemonas and has been on TOBI for a couple of days - which he hates. He says it tastes bad and it makes him cough as soon as he starts breathing it in.
