<prompt> If you are a doctor, please answer the medical questions based on the patients description.I was in a car accident 8 days ago. The last few days I have had abdominal pain. This morning I had severe cramps and went to the restroom. I had a small BM but then was extremely nauseated and vomited. I have had these symptoms several times today and the last BM I noticed bright red blood mixed in with my stool. Should I be worried?  <response>: HIT hank for asking to ChatDoctorI can understand your problem and this could be intestinal infection and most probably Protozoa infection is likely, if I would be your doctor then I would treat you with the following medicine.1 Tab Metronidazole 400 mg twice in day for 7 days2 Tab. Dicyclomine with Acetaminophen three time in day once pain stops no need to take thisI hope you would feel much better with this, take care and have nice day.
