Thanks for posting your query at DoctorSpring.com
I am Dr.R.K and I am pleased to assist you.
There are many different causes of blood in stool. Some of the common causes are hemorrhoids, anal fissure, polyps, colitis and malignancy.
Since you are not constipated, it is less likely to be due to hemorrhoids or anal fissure. Moreover the doctor did a rectal examination and he would have diagnosed these conditions. Since he did not mention anything about these two conditions, they are less likely to be the cause of blood in stool in your case.
Since you have abdominal cramps also in addition to having blood in stool, colitis is the more likely cause. A colonoscopy test may be done to confirm it. It is a test in which a long slender tube is inserted through the anal opening to look inside the colon.
You need not go to ER as long you can tolerate the abdominal cramps and the hemoglobin is not dangerously low.
You can fix an appointment with your GI doctor for this test.
I hope that answers your question.
Let me know if I can assist you further.
Patient replied :
Having totally different pain now.Had a colonoscopy and endoscopy and mild gastritis was found along with internal hemmrhoids. This test was done 8 months ago. 5 months ago I began having waves of excruciating pain and swelling on luq and llq. I have noticed spots of white mucus in my stool. Red blood on and in the middle of my stool as well as some nausea. Could this be anything new as I just had the colonoscopy not too long ago? My bm's are daily, mainly loose, no diarhrea. My GI Dr wasn't concerned with these symptoms last month but it is so bad that I can't do daily tasks.
