OH I am so sorry I did not respond to your email. I feel really bad. How is your daughter doing? Have you seen a doctor about her pain? For me the pain lasted, on and off for about 5 months before I went on a gluten-free diet. After the change it took about 3 months for the pain, gas, and bloating to subside.
I just saw this and I'm not sure what my original post was, but, I will say that, before I was diagnosed and got rid of the evil gluten, the nighttime pain (on my left side particularly) was near to what I would term "excruciating". And I've given natural birth to a nearly 10 pound baby and a girl and also had kidney stones so I'm not a complete baby about pain...
