I have had severe heartburn/indigestion for three days now. Keeps me awake at night. I have tried tums,,,,baking soda w/water and pesto bismol. In the morning it’s better but still present. 8 hrs ago I ate 2 scrambled eggs an half a cup of milk still slightly present but not gone completely. Just ate chicken noodle soup with crackers and am hurting pain level 8. Pain is under my left Breast rib cage area. With slight burning sensation. Burping a lot. BP is normal.
