i have RUQ pain, i have been on a no fat diet for months, I have had an US, CT Hida scan and will be having a scope done soon, they think it is my galbladder, but sometimes without eating fatty foods if Im stressed i have an attack, and these attacks put me to my knees. I had my son naturally and I would rather go through child birth again then continue with these attacks, that s how painful they are. Is there anything else this could be.
