Im a 22 yr old female who has been having a sore & bleeding anus for a couple days.i havent been able to pass a bowel movement in about 4 days and last night the left side of my stomach started hurting. should i go to the hospital? or wait it out?

Try a fleets enema to facilitate the passage of stool. If that does not work, you may have fecal impaction that may need digital evacuation by a doctor. You probably have an anal fissure, and it is imperative to prevent constipation by taking laxative/stool softener. These are available over the counter, consult a pharmacist. Drink enough water so that your urine is mostly colorless.
