Hi - I had gallbladder issues during my first pregnancy. I highly recommend having the blood tests done as there is some condition that can happen which can be deadly - so you want to rule that out. Since my pain came and went, I was not interested in having the surgery while pregnant and three + years later, I still have my gallbladder. They also did an ultrasound which confirmed about 5 small gallstones.
What I did do which helped immensely is add CHOLINE supplement to my diet. I did NOT follow a very low fat diet, as I suspect my low fat diet caused the gallbladder problem in the first place. I visited www.gallbladderattack.com and read information there and was surprised that low fat and no fat diets can lead to gallbladder problems. It made sense to me once I thought about it - if you're not eating a lot of fats, the gallbladder can get sluggish and sludgey as well. So in my past 3 years, I keep to a moderate fat diet anda void obviously fat-laden foods like pizza (my almost-surgeon said is the #1 food that puts people in the E/R with gallbladder attacks and yes, that is also what I had eaten). I also do not eat lasagna, or anything really heavy in cheese. I also used the receipes on the above website.
I still have the gallstones, but they have not caused may an pain since my E/R visit in Jan 2009.
The pain can be in a few places - the upper right quadrant of abdomen, just under the lower rib. It can be in the back or front. One time I had pain that radiated across the entire diaphragm, so it went from the right to the left side. I also had pain in my right shoulder area.
Hope you are feeling better and your pain is a one-time only experience.
