Hi Cleo
I'd never heard of a gallbladder attack prior to your post, and to be honest until I looked it up, I had no idea what your gall bladder actually did.
One thing I did note while reading about gall bladder attacks, was a mention that discomfort from the lower right of the rib cage after sitting forward for some time, can be an indicator of a gall bladder problem. I have had that kind of discomfort for a long time. Maybe I should get a checkup after all. Hmmm sucks to be me!
