Re: stomach pain or trapped nerve
I just suggested it. Since my medication for Crohn's wasn't working for the pain I was having, I asked if I could get a HIDA scan, he said sure. Everyone, including the doctors and myself, was floored by the result. I even told the technician that I was there just to rule it out. I did not have gallbladder disease symptoms; I had all left/central pain.
The scan was easy and fairly painless. They put in an IV and lay your on a table similar to a ct scan. They inject a radioisotope and watch it go in and out of your gallbadder (takes about an hour for that part) then they inject a hormone (CCK) which simulates a fatty meal. That's when it became uncomfortable for me. Severe nausea and cramping. It didn't last long though. The whole test took about 2 hours.
I had my gallbladder removed this past Wednesday and I am feeling better already.
You have classic symptoms of gallbladder disease. I am always confused when I read posts like your's and you haven't had a HIDA scan. Seems like a no-brainer to me.
Good luck with it all, I hope you feel better soon.
