I have been a little constipated the past few days. a little while ago, I went to the bathroom and had a small bowel movement, and this big gush of bright red blood and a few little clots came out. Then about 1/2 hr later, I had another bigger bowel movement. I m feeling a little better. Prior to this, I have had lower left back pain, felt like a pulled muscle between back and tailbone, its almost gone away after 10 plus days. Now I m wondering if it could have been a kidney infection possibly? It seems like now that I passed solid waste, there s hardly any pain there. Also, this morning after I ate a little cereal, I was nauseas and had some throwing up. I haven t had any fever, just lack of movement from pain didn t help with constipation. I am waiting for a call from my doctor.
