It is difficult to guess what is wrong. I have a 2.8cm gallstone for 15 years, if I get an attack my collar bones are killing me and I get tight around the waist. For the 1st time in 15 years a few months ago my gallbladder was hurting when I pushed on it, so I went for an ultrasound, because I also had a belly ache. The gallbladder was fine and they did an EKG because that ache could have been from the heart, who would have thought of that. The MD said not to get my gallbladder out and wait since it was the first time in 15 years.
