Actually disregard that post. I just saw where they couldn't explain it but it was benign.
I definitely agree with a 2nd opinion.
As a GI nurse we usually are the ones to diagnose gallbladder disease but not ones to follow up with. However I have some (limited) knowledge on pathology and when we see something like indurated mucosal heaping that is usually associated with raised thickened mucosa raises red flags.
I'm no doctor, pathologist or scientist so I don't want to alarm you but it never hurts to have a second opinion.
