Those follow up scans are always nerve racking, I can't decide which is worse, waiting to have the scans, having the scans, or waiting for the results. I try to be kind to myself, and do things I enjoy, such as seeing a movie, going out with friends, getting a facial, etc.
As for elevate liver enzymes - yes medications can do that, I know, I've had that happen to me. Speak with your doctor and find out why the follow up tests have not been done. My PCP has me schedule the tests and appointments at the end of my visit.
