Crohn's or Polycystic Kidney/Liver Disease

You should talk to your GI and your liver Dr. It is impossible to tell over the internet what is going on.

I have had pain in the right upper quadrant for years and went through a lot of diagnostic procedures to figure it out, and I only have Crohn's.

Depending on how debilitating this pain is you can consider a variety of options, including doing nothing. As a basic screening, though, it seems like either or both DRs would want to do blood tests to look for markers like inflammatory proteins or liver function tests.

The diagnostics I did were abdominal C/T, HIDA scan and bowel MRI with contrast. My upper right quadrant pain appears to be simply constipation. I played with miralax for a while but have settled on psyllium as a way to keep my bowel movement more regular.
