My spidey-sense told me that I should have asked for a copy of the radiologist's report of my MRI in addition to picking up a copy of the films, which I was told my doctor would need. I was also told that a copy of said report would be faxed to my doctor, so all would be revealed at today's visit. The doc would help me understand the report and point out the relevant images on the films. This is how it's worked before with another doctor.
Yeah. Not so much with this one.
So I still don't know exactly what's going on. I've taken a look at the films (well, duh; I can't just sit on something like that and NOT peek), but the bright lines that I suspect are significant may turn out to be noise or something.
One thing I know for certain. Tomorrow I will be requesting a copy of my own from the radiologist. I am not going to sit around and wait for my doctor's office to get their copy and call me with the results.
