2 weeks to get an ultra sound...? Really? You could have a stone get stuck by then. Next time you have those pains go to the emergency room, see how fast they do one then.
I had the same deal 6yrs ago, it was gall stones and I was told if I didnt have it removed before a stone got stuck that they would have to open me up and recovery time sucks for that, but if I have it done soon then its ez ...in and out same day. Work in 5 days. I of course took the ez way. Anytime I would diet I would get these pains. I didnt know what they were until I got the attack that was so bad I thought I was going to explode. What insurance do you have?
