Hi, I had H. Pylori (3+) in 2005, no ulcers in stomach, no treatment at the time. for the last couple weeks, I started having empty stomach pain, insomnia (could not sleep until 6-7AM,then I use sleeping pills), I started having blood stool yesterday. I went to see walk in clinic, the doctor told me to find a family doctor for treatment. what's the possible cause of this?
