I had the exact same thing that griff described happen to me. Exactly....heart , mental, every thing else before finding a Dr that helped me find a specialist, who helped me find a surgeon, who helped my find another surgeon that specialized in the Lap nissen fundo.
I agree on going to go find another DR. The swallow, for me, showd I had no hernia at all and the manomatry showd I had a 6 out of 14, which is normal range, LES pressure. The manometry won!!
