My answer to this question is if you are the question then it is probably then you probably need to go into the hospital. I would recommend avoiding going in on a Friday, Saturday, or Sunday because that is when the hospital is short of staff. Many doctors have the weekends off so you probably wouldn't be seeing your GI on Saturday or Sunday.
It is very important to go to the best hospital in your area because it really does make a difference. Here are the US News and World Reports ranking for hospitals that treat Digestive Disorders http://health.usnews.com/usnews/health/best-hospitals/search.php?spec=ihqgast&
