I'm almost 27 weeks pregnant and I found out a few months ago that I had gallstones. Early yesterday, about 12:15am, I had my first gallbladder attack. The second was later on while I was at work. I thought they were contraction-like pains, but they lasted too long to be normal. I went to the hospital to get baby checked and had forgotten until then that I even had the gallstones. Baby was fine, but then upon doing the ultrasound for my gallbladder, kidneys and liver, it was quite obvious where the pain was originating.
While waiting for results I came across this thread and became hopeful that there was a way to get relief. Immediately After lunch today I had another attack. I guess it helps me narrow down that even slightly fatty steak, deli meats, and spicy foods especially are some of my triggers. I sent my mother out for castor oil so as to use that for my future episodes, and next time I'm in the heath food store, I'll look for cleaver's to start a regimen of that. I also found that laying at a 35 to 45 degree angle relieves my pain almost immediately, especially when it is at its worst. It doesn't seem to be a permanent end, but it lessens the pain greatly so I can continue on with my day.
