Hi at @reliefforchild welcome to Connect. You may have noticed I moved your post to this thread on Chronic abdominal pain so you can learn about what has caused other peoples chronic abdominal pain and what has worked to treat it.

It must be so scary for you and your daughter that a reason for her pain is not being found.

Hoping that members like @mamacita @carolel @matt2134 @astaingegerdm and @sacrifice2121 will have some thoughts for you.

You mentioned that your daughter was having migraines prior to the abdominal pain. Is she still having them? Also, have you been able to find anything that betters or worsens the abdominal pain (food, drinks, standing/sitting)?
