I have blood in stool, about 1 month ago I had fresh blood in stool 4times then stopped , then I went to hospital to do Ultrasound, Colposcopy, Endoscopy, and Biopsy. I was diagnosed with Chronic Gastritis. Doctor said it may be my stool is too hard and it tears my anus a bit. but today there still a little fresh blood (just like a little drop of water) on my stool. So should I worry ?
