Welcome to Healthcaremagic.com.
I had gone through your question I can understand your concern about your stomach upset
The history and symptoms of you are suggestive of gastritis
with acid reflux
As you had under gone the H. Pylori kit antibiotics which is a combination of two to three different types of antibiotics, if not you need to try one as soon as possible.
Because the pain is because of ulcer in stomach it may take some time.
Avoid oily, spicy, junk foods.
Avoid late night meals, drinks and smoking
Have regular bed timing, and meal timings.
Raise your head side of bed at least five inches.
You can try IV pantoprazole
under the guidance of emergency room.
