Over the past year 4-5 times DD has had sudden outbursts where she is very uncomfortable, at times screaming in stomach pain. She will vomit 1-2 times, and within an hour or 2 it's over. This has happened at home a few times, sometimes the middle of the night, so not right after she's eaten. It's also happened at school, I picked her up about 1/2 hour after she threw up, I never would have known she was sick. She's allergic to peanuts, and she has vomitted after being exposed, but as soon as she eats it she's sick. This has happened in the middle of the night, or once within a few hours of waking when all she had had was cereal. Does this seem strange to anyone else? The last time it happened I started thinking how off it is. Usually you're sick for a day or 2, not a few hours. We're going to the dr. in a few weeks, but I'm just wondering if anyone else has experienced anything similar.
