Elevate the affected area of the body and keep covers off it. Apply cool compresses to the area, though the pain may make it difficult. There are many causes for red stool, or what looks like blood, in the bowel movement. Food, bleeding, medicine, hepatitis, diverticulosis, Crohn's disease, cancer, polyps, ulcerative colitis, and malabsorption are but a few. For bleeding, seek medical attention for evaluation.
Constipation can cause mild bleeding of hemorrhoids.
For unusual color, review the diet intake from the previous 48 hours. Review drugs for possible cause. Review for problems other than stool color. Make an appointment if unusual color remains after 72 hours, or if bleeding increases. Seek prompt attention if weakness, dizziness or lethargy occurs with black or red bowel movements.
