Hi @kaylabrooks326 and welcome to Mayo Clinic Connect. I have been in your shoes and the hike is not fun! I woke up in 2007 with the worst pain I have ever felt.

"The mildest and most common symptom of gallbladder disease is intermittent pain called biliary colic. Typically, a patient experiences a steady gripping or gnawing pain in the upper right abdomen near the rib cage, which can be severe and can radiate to the upper back." --- Gallbladder Disease: https://www.hopkinsmedicine.org/health/conditions-and-diseases/gallbladder-disease

Can you answer a couple of questions? Is the pain continuous or does it come and go? When they did the CT did they do it with or without contrast?
