Hi, I've been reading your post on Gall Bladder, and the profile fits me. I'm 64, I had a spell last nite, cleaning up the kitchen, ate 1/2 of small choc. cake, later on, get the sharp pains, lower belly, buzzy head, chills. Pretty soon feeling nauseous, then I vomited while having the diarreah. I have passed out twice on occasion during these spells, not recently tho. Later in the night, the sharp lower belly pains continued, and I passed a little blood, but that's over now. I've had these spells over several years, have had ultrasound for gb, but negative. Recently had endoscopy, excess acid, etc. Haven't had colonoscopy for a while. In your opinion, does this sound like GB? Really appreciate any info! Oh, I also get pain under right ribcage also, and upper back. thanks, Susan.
