My daughter was riding her horse on Saturday when it fell and rolled over her as she lay on the ground (fortunately a soft, tilled arena). She was seen immediately by paramedics, and other than a nosebleed, she didn t have any complaints. About 24 hours later she started complaining about miscellaneous aches and pains, which I would expect. This evening, though, she started complaining that her stomach hurt and she has diarrhea , which she reported to me was red. Unfortunately she only told me this after she had flushed. She hasn t eaten anything that I would expect to cause a red color, but she did have blood on her tissue once about a week prior to the accident, while she was constipated. Should I take her to the emergency room?
