Hernia/Twisted Intestine

I did have some cramping over a few weeks time period but it seemed to come and go. I was checked out and nothing came of it. I had x-rays and a CT scan. Nothing was abnormal. My next step

is a ultrasound. I haven't had any cramping for about 6 weeks now but am paranoid after hearing stories like yours. I've never thrown up so I guess if that starts that might be my first clue something is

wrong.
