I just wanted to also mention while my pain does increase it's not just a reaction to pain, it's almost like my brain is experiencing the fight or flight response.

And while I rarely eat out, when I do I tend to go when things aren't busy, because it's the people in the booth next to me rhythmically kicking, that I struggle with the most.

OP: Has your daughter tried swimming in warm water? It will reduce stimuli and it might really help her.
