What Causes Stomach Pain, Low Appetite And Nausea Post Treatment For H Pylori?

5-months before I was diagnosed with h pylori infection and was given the triple therapy for 14 days which included two antibiotics and one ppi. I still have stomach ache and low appetite and nausea even after being tested negative for the infection. The gastroscopy results are also normal. Another symptom is whenever i bend, or something get pressed against my stomach, my stomach ache increases and I feel uncomfortable. I have two different places where my stomach hurts, one is right in the middle may be two inches spot above belly button and the right side of my stomach in a semicircle starting under the rib from the front to the end. I get this pain if I eat little bit over my capacity and my capacity to eat has reduced so much to the point that I just eat one full meal in a day which is half the amount I used to eat as a full meal. I m 43 yrs old female.
