ulcers in the past

ok..i had a h pylori 2 year ago and was positive.  I was told that this can casue ulcers and becasue i was positive i had one.  SO i was given meds..and took them.  I took this test again a week ago and it was fine.  My CW called me and asked me about this.  I told her what i just told you guys.. Now..my ? is this: If i had a ulcer in the past..and my test is fine..does it mean i still have one???  i fell fine! If i do..how do i now?? if i do..will i not have my surgery??? I dont want to keep calling my CW over stupid ?s
