### input:
I am a 50 year old who was in the ER last night for several hours after vomiting non-stop for 2 and a 1/2 hours. I also had chest pain right between my breasts. Felt like an elephant was sitting on me. They gave me multiple doses of phenergan, morphine, zofran, and Benadryl trying to get it to stop. Although I was freezing cold, no one took my temp after the initial admission vitals but when I got home it was 102.7. They did blood work that the doctor said was all over the place but not alarmingly bad (have no idea what that means), an EKG after which I heard something about throwing PVC s, and a CT scan of my abdomen which showed viral Gastroenteririts. Sent me home with zofran and Lortab because he said the insurance company would not pay to keep me overnight unless I was vomiting for 2-3 days. I am taking the meds, resting and have managed to keep in about 6oz of diluted Gatorade. My question is about the CT. Why did they do it and what would have they seen to give them that diagnosis? I found that very strange to do.

### output:

Thanks for your question on Chat Doctor. I can understand your concern. Severe vomiting, chest pain, chest heaviness etc. are commonly seen with peptic perforation and intestinal obstruction. Both of these conditions need urgent surgical intervention as a treatment. CT scan of abdomen was done to rule out these life-threatening causes for your symptoms. Since your CT scan was showing only gastroenteritis and not showing any perforation or obstruction, you sent home with medicines only. So don't worry, you will be alright with the medicines you have given. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
