The most common causes of blood in the stool in your age group is hemorrhoids or anal fissures. Bleeding from polyps and cancer is less likely. Certainly any type of constipation or hard stool can irritate the rectum and cause small tears of fissures.
Given the fact you have abdominal pain, you may want to consider an endoscopy - either a flexible sigmoidoscopy or colonoscopy for furthre evaluation.
Further testing to consider would be a urinalysis (looking for any kidney stones which may manifest as back pain) or abdominal/pelvic CT scan to look for any masses or inflammation which can cause abdominal discomfort.
Followup with your personal physician is essential.

what color is the blood??
was the stool liquid, ie diarrhea? Was the pain in your belly or was it that the stool caused anal pain as it passed?
dark red or fresh red.
fresh red could be anal tears or hemorroid
It was fresh red. The pain is in my belly. But why the lower back pain?
I've been to my doctor and he says that he couldn't find anything wrong. I continue to have stomach pains though, and continue to bleed when I go to the bathroom. What is going on with me?
Hi, I would say you have a fissure. Try this site and its recommendations and see if it works. I would avoid the NTG though. I would also be weary of doctors, quite often they don't know what's wrong and before you know it you'll be under the anesthetic. Always get a second and third opinion, quite often they'll be different ! Also try naturopaths. The best thing is to nurture the body over time with good food, excerise, sleep Meditation as well is very good as it releases toxic emotions and feelings.
Hopes this helps..
Have your symptoms subsided? I went through this same thing about 2 1/2 years ago. My bowel movements were very painful (when I could go) and I would have severe spasms (Felt like a cattle prod shock up my butt) whenever/wherever they wanted to happen. Due to the severe bleeding, I became very weak and I couldn't even get up from the toilet. I had to wear a pad all day and night because everytime I bent over or picked something up (strained) I bled. I had a colonoscopy done and to my surprise was clean. No polyps, lesions or fissures. The spasms pretty much stopped after the colonsocopy and they told me that due to the 'straining' during bowel movements, I probably keep tearing blood vessels. I have found that increasing my water intake during the day has softened my BM's and I haven't been bleeding. I hope things are better for you. Trust me, I know how scary this is.
