question: Hello, I have a just barely 3 year old who is very small, technically failure to thrive...although I would say she is thriving in every way, but she is small. We have already had all the basic tests done (Celiac, Thyroid, Metabolic Panels, and most recently an upper Endoscopy), all of which are normal. The last four months she has been complaining of belly button pain, sometimes back pain at the same time. The complaining is 3-4 times a day, she just had a UA with Micro/Culture and Stool testing for absorption done. The urine was fresh, the pH was high at 7.5, could this be due to her Prilosec medication? Also, she has mucous in her urine, but everyting else was normal...including the culture. I m thinking something kidney related, based on the fact that her bowel movements are normal any thoughts? I haven t heard back from the GI specialist yet, but I want to be prepared when we speak. Should I ask for an ultrasound to be performed? The constant tummy pain is a worry, and we can t seem to get to the bottom of it. Thanks, Kelli
