On Tuesday The 28th Of Aug. I Started Getting A

On Tuesday the 28th of Aug. I started getting a terrible side ache and my lower abdomen just started rumbling. Other people could hear it, it was so bad. About 6 hours later I had to throw up. All it was was water. I wasn't hungry that day and hadn't had anything to eat. It hurt to move on my right side. So, thought that it would go away, but it didn't by Thursday the 30th. I went to the ER and spent 6 hours doing tests. CT scan, ultra sound, blood work, urine test. They came back and told me everything on my right side and lower abdomen was twisted. Nothing specific exactly. But to follow up with a surgeon. Well, they sent me home and Friday I called and made an appointment with and intestinal doctor, but couldn't get me in til the 6th of Sept. My lower abdomen and swelled up to 2 pant sizes since Thursday and it's Friday now. I'm thinking I should be concerned about this getting bigger. Should I be concerned, and should I go back to the ER for pain meds. cause this is painful. I don't want something to burst and die. What is your advise?
