I took 800mg of pure ibuprofen (a NSAID) 3x a day starting this time last year (severe butt problems), went to maybe 2x/day after some 2 mos then 1x/day another 2 mos after that. In total 800 mg+/day for 7 mos until IT HIT.
By Feb suddenly all hell broke loose. I was burping (if that's what it is!) every 5 sec or so, I knew something was wrong.
Doc's all assumed and are still assuming (general, GE, and yesterday an ENT because of my throat symptoms with it) I have "acid-reflux disease" (Gastro-esophageal reflux disease, GERD). I was on 1 Nexium/day for 4 mos, during which my stomach began to feel almost always nauseous (basically right after my endoscopy, which showed mild gastritis). The other month I was allowed to go to 2 Nexium/day (both for the throat version of this and to try to help my gastritis). I'm still suffering quite a bit.
I am praying the NSAID assault didn't lead to genuine reflux disease, which looks hopeless (and feels so for me, who's still suffering about daily). Usually 1 only reads about NSAIDs leading to gastritis and ulcers, not "ruining the sphincter" (i.e., true GERD). I'm honestly hoping partly that it's just a symptom of gastritis. But then, I don't know what to wish anymore! Guess we shouldn't wish for anything else!
But I am convinced that whatever it is, my NSAID use was the instigator. I could kick myself forever for relying so heavily on them!
So yes, I can believe you've hurt yourself with Advil. I just hope you can rectify it!
