It is very important when you have an ultrasound done, that you ask for a copy of the results.
It won't only say that you have stones. It will give much more information. Often the size of the stones, inflammation or not. But also what your kidneys and spleen look like etc.
So in my case got the info of the inflammation and wallthickness from the 1st US. It also said that the stone was in the neck of the gallbladder and I assume that's what hampered the bile flow and created the problems.
