Over the last few years I have had a few episodes of waking up in the middle of the night with a feeling of tenderness and dicomfort in my sternal area that increases in strength and becomes very uncomfortable. I have taken maalox with fair results and it usually subsides. That is until last week, after having the stomach flu and diarrhea for 3 days straight...I awoke at 2:00 a.m. knowing I was starting to have one of those episodes, so I took my maalox immediately. For the first time the maalox didn't relieve it at all and it just kept getting stronger and more unbearable(pressure,squeezing), making it hard to even breathe! I ended up going to the E.R. by ambulance. As soon as they gave me 4 baby aspirin and a nitro, the pain subsided! I had an EKG, chest Xray, lab work, everything came back fine, so the doctor told me he thought it was reflux and put me on prevacid. How could reflux cause such excruciating pain? Has anyone else experianced this?
