I keep experiencing a sharp pain around my anus when i sit on the toilet to urinate or pass stool. blood turns the water red as i do my business. :(?

Anal fissure: Is the most likely cause of this which is a small "split" in the skin at the anal opening. It usually occurs due to stretching of the skin with passage of large and/or hard stool. Increased fluids along with bulking agents such as psyllium husks used daily to soften stools will help these heal in about 2-3 weeks in most cases. You can read about this on line and learn more.
