I’ve had left sided abdominal pain for about 3 weeks now. I have had my CBC checked and everything came back normal. I’m 26 years old and in general very healthy. I have had an increase in constipation lately, but had two good bowel movements the past two days. I keep thinking the absolute worst like stomach or pancreatic cancer, but wouldn’t that show up on a CBC? My older sister tested positive for h. Pylori, she told me to get blood work to test for that.
