Since pregnancy I have been having severe heartburn attacks (2 years). Before pregnancy I had never experienced it. Ever. It is excruciating. My hands start to tingle because I'm pretty sure I start to hyperventilate. They started lasting around 20 minutes, grew to 45 minutes and this last one a few days back lasted 5 hours and landed me in the 24 hour clinic doubled over in pain I can't move or talk in the peak of it.
I am having some tests done, first lot came back negative a few months back. But after last weeks marathon of pain I am investigating further. Don't think it's GERD because I only seem to be having them every 3 months or so. And theres nothing in particular that sets it off either. I'm so confused.

Has anyone else experienced something like this? And was it after pregnancy?
