Hi, I had a gallbladder attack 3 days ago and turns out I have small gallstones. The only pain I m having now is a dull aching pain in my lower right side of my back. I can t bare the thought of surgery. I heard about a medication Ursodiol (Actigall) or Chenodiol (Chenix). Would this help to dissolve the stones? And am I able to purchase it over the counter? I am a 56 yr old Fem. CBD measures upto 3.4 mm, not dialated....what does this mean? It was in my paperwork from the ER.
