I went for endoscopy because I was having stomach issues, but no pain...just horrible silent reflux that made me choke and cough a lot and feeling of fullness after eating small meal and sometimes vomiting urges....after endoscopy I went home, ate meal and had a horrible stomach pain that radiated to my back. It lasted 3 hours. I called doctors office and they told me to take antiacid. Next day the pain was less, but it is still there when i eat an it is quite disabling. Is that normal after endoscopy??? Could it have been caused by the biopsi they did? I was painless before!
