Went in for the CaT scan on Saturday morning. Nothing unusual to report other than the contrast dye.
I told my daughter they have a special cat with a magnifying glass fitted over one eye and that he looks you all over upsy-downsy and meowfs if he sees something.
The gal says “Ok, we need to inject this into you so we can see the bone and bits-o-stuff.” Bits of stuff probably wasn’t the technical terminology. But she continued on, “Well, a lot of people get a warm fuzzy feeling, or flushed, or sometimes hot, but a very common side effect is that you’re going to feel like you really have to pee badly.”
“Oh, so I should go now? I’d just as soon go now.”
“Oh sure, but don’t worry, I haven’t once had anyone wet themselves in the scanner.”
(How about just afterwards?)
They put me in the scanner, did some things, did some other things, and then she says “I’m going to have the machine inject the dye now.”
“WHOA! THAT IS FASCINATING!”
The warmth started at the roof of my mouth, went to the back of my mouth, and made a beeline for my bladder.
“THAT IS SO WICKED COOL!”
And a few seconds later, it was gone.
Maybe they’ll call me today with the results.

Yeah, I’ve had a couple of those. I remember getting a metallic taste in my mouth as well as what you describe.
The procedure I don’t like, as far as Radiology goes, are MRIs. I’ve had one of those, and that will last me a lifetime.
I’m not claustrophic, but you’re in there so tightly, you can’t lift your knee more than a couple inches. And you have to stay perfectly still while they do the damned thing. I was in there damn near 45 minutes, and I couldn’t wait to get the hell out.
I’m rather deep in the chest and literally had inches of clearance and I found I do not like MRI’s at all, either.
They are so loud and jarring that they were uncomfortably hypnotic, too.
Fingers crossed! How’s everything else going?
I am telecommuting two out of five days a week to keep from overdoing it. Even so, when I get run down I have pain spikes. On the whole it is getting better though. Still no rusty dagger in the neck sensation that I’ve had for so very long. Very very happy with that. The pain that is there is mostly taken care of by meds, unlike before, where the nerve pain was only partially helped.
Hah! The Baron is alive! I knew they didn’t kill him off.
I hope that you receive good news today!
