I've been told I have internal bleeding
, however the source is unknown. I've had 7 blood transfusions since May '05. I've had UGI, BE, colonoscopy, ct of abdomen, endoscopy's, and numerous other tests. Why is it so hard to find the source? I had my gallbladder removed on 4/25/08. My last transfusion was in January '08. On Thursday 4/29/09, my Hgb was 8.5, which I know has dropped since then, because I vomited black stuff yesterday. Hemoccult tests have been positive.
