I Was Diagnosed With Gerd At The Emergency Room After

I was diagnosed with gerd at the emergency room after having bad acid reflux for weeks then on that day I vomited and there was a small amount of dark red blood, I was prescribed zantac everyday for a month. A whole month later and I feel worse than I did before. Instead of getting better things just felt worse with each passing week. Now it's to the point where the pain is nonstop. What's going on with me?
