Hi Carolynn,

What were his symptoms pre-fundo? Did he report pain, did he have bad
breath, difficulty sleeping etc.? Were there particular behavioural
patterns that disappeared once he had the fundo? I'm no expert, but I
guess if some of his pre-fundo patterns come back, it might be a sign
that things are not right. Have you asked if he can have a barium
swallow to check if the fundo is intact? (I know that other people have
reported that it's not totally reliable, but at least it's a start, and
sometimes reflux shows up on the pictures as well).

Good luck,
