Can your gallbladder be on the left side? I have all the symptoms of gallbladder attack, but it's on the left side. I just came from having an ultrasound, chest x-ray and blood work, they found nothing. But I swear, it's the same symptoms I read and talked to others about the gallbladder, just it's on the left, upper back, under shoulder blade, continuing around to the front and closing in on my chest. Can't take deep breaths, lift my arms above my head or reach down.
