Actually, I get heart burn alot. And usually i lay down because it's more comfortable that way. But if i'm standing, I feel like it never goes away. So, really I don't think either way is good or bad, but whatever is comfortable to you, is what you should choose. You won't harm anything by standing.
It really depends on how bad it hurts. Sometimes lying down can release it and then sometimes standing could also relieve it. I have heartburn too and take Prilosec for it and it helps out a lot! (:
I Never heard of that.?? Werid Try
