I drank a tall glass lemonade five days days ago, and six hours after drinking it (and eating nothing in between), I started having a sharp, uncomfortable stomach ache which moved up into my chest, giving me heartburn I THINK ( not a burning feeling, like a really bad stabbing, pressure feeling) in the center of my chest. The last time I had a little lemonade a long time ago, I started getting the same pain in my chest but not nearly as bad, and I took a nexium which stopped the pain immediately.
I've had to sleep sitting up the past four nights because if I lie down for even a minute, the pain starts getting worse. I've had the pain non-stop for five days, varying in degrees of pain, from a dull ache to a sharp stab, and it seems to be unrelated to anything, eating doesn't make it worse or better, the pain just seems to have a mind of its own.
Also, the pain seems to take turns between my intestines, stomach, and chest, and I'm bloated due to constipaton. I took a nexium every day, and drank some antacid mix-in, tried a pepcid, tried tums, tried baking soda, tried vinegar, drank milk, ate bananas, but nothing's helping. What should I do? What could this be?
