when to go to er for heartburn

When to go to the emergency? I needed to stop taking omeprazole for my h pylori retest. GI says I need to be off for 10 days. I was already starting to have symptoms like this even before I went off the 20 mg of omeprazole. I feel like I am damaging my esophagus even more. I have burning in my throat, feeling like food is stuck in my sternum and left breastbone, burning gums, difficulty breathing and talking, difficulty swallowing anything - hurts to drink water, broth, yogurt. The pain does not stop. Hurts after I eat, before I eat, as I eat, when I wake up, when I sleep.. I am taking gaviscon (liquid and chewables) and it's like taking nothing, it doesn't ease the pain at all. I tried apple cider vinegar and water, that does nothing. I am worried the h pylori may have left severe scarring of the tissue in my esophagus. What do I do at this point, just suffer until the day of my endoscopy or am I actually making things worse?
