Same for me, never thought I had what they call GERD or any heartburn. I seldom drink alcohol, maybe one glass at a wedding or Was born with anal fissures, childhood agony & suppositories, now past 2 months gradual increase in pain & persistent now in upper central abdomen (stomach) that radiates up under my LEFT Ribcage to the waistline (at the navel) and through to the mid and lower back, along with abdominal distention from below breast to pelvis, recurrent Diarrhea for past 2 months as well as intermittent urge to defecate but unable to, feels like a blockage at muscle regardless of straining, and no pain relief. Can burp, pass gas without any relief. Unable to eat solid food, as increases pain and I already feel over-full! Sticking with liquids and smoothies. Everything I ingest causes diarrhea, but pain doesn't subside.
About 30 years ago, it was assumed that I had IBS, then learned that I have same symptoms of abdominal pain radiating to back when eating yogurt; then years later told I am lactose intolerant and found over the past 30 years I would get this pain from eating yogurt or drinking milk, which I have cut from my diet, along with cheese, yeast, processed, smoked, pickled foods and no alcohol or meds, vitamins, etc. as never tolerated well.
Then after on blood thinners for unrelated blood clot also prescribed a sulfur medication for resp inflammation, I was not told to cut back the blood thinners and developed a duodenal ulcer, with vomiting up blood and stuff that resembled coffee grounds for a week, which my GP did not take seriously, until my daily blood work had shown high INR levels, but Doc didn't bother to tell me for 5 days. Told to go to ER and was hospitalized, had endoscopy by Spec. & told Duodenal Ulcer/Gerd and prescribed a variety of antibiotics for H.Pylori and Pariet. Subsided for a few years, now this.
Not sure if same thing or what....on pariet again for past 2 weeks, with no relief. What else could this be?
Well, I'm not sure what to tell you about all that other stuff, but I will say GERD can cause some really weird symptoms. I have or had GERD and very seldom experienced heartburn or any kind of pain at all. It was mostly nausea, bloating, and occasional fire-burps. Lots of bad tastes in the mouth, too. Should also mention that I also had gastritis and hilatal hernia confirmed by endoscopy. All other tests returned negative.
But it's really crazy how GERD affects people in different ways.
My advice? Don't drive yourself crazy trying to figure it out. Doctors make really good money to do that, plus they know what they're doing. If you continue worrying like that you'll end up with an anxiety disorder. And believe me, you don't want that.
That's not to say you should be a passive patient. If you trust your doc, engage him. Drill him with questions. Directly or indirectly, make sure he knows you're no dummy and you want the straight dope. But do try not to second guess them unless they give you reason to. Give them a chance. Gastro problems are often difficult to diagnose and as you well know, it can take a while.
I wish you nothing but the best.
I almost never have heartburn with My Gerd. The GERD was confirmed on a barium/ water x ray. BUt i never have heartburn, just the pain.
