Hospital Gown, House Coat, and my Red High Heels

Last night was my MRI to look at the veins and arteries of my kidneys to help the surgeons determine which kidney to remove (which one will be easiest to remove) and to make sure both kidneys were functioning at a level which will enable my body to function with only 1.
So here's how it went. The test was scheduled for 630pm, I was to arrive at the hospital by 6, and was to fast for 6hrs prior.
Upon arrival I am given a questionnaire to fill out mostly pertaining to prior surgeries and any instance where I would have metal in my body. Thankfully I don't have a pacemaker or screws in any bones, and the tattoo that I have is over 3 weeks old (its 8 years old actually). I fill out the form, and get to change into the hospital gown, and robe. Everything had to come off except underwear and shoes. Of course I managed to still look fashionable in my red high heels. Or at least as fashionable as one can look in such a situation.
I do admit it was a joy having to wait in a general waiting room with friends and family of other patients while in such a fashionable outfit, instead of a waiting room normally reserved for patients who have had to change.
Needless to say the wait felt rather long, due in part to the fact they didnt call me for my test until 7pm.
At this point a technician went over the form I had just filled out ensuring I fully understood everything and walking me through the MRI.
I laid down on the "bed" and the tech went vein hunting. My veins are not easy to find on the best of days, and they like to hide when I am not well hydrated. Being as I had been fasting for over 6hrs, it took 2 techs 2 arms to get a vein that worked. Did I mention I hate needles? Super fun.
On the "bed" I have a needle in my arm, some cage-esque device over my abdomen, and am strapped in. The vein on my left side had a tube which would carry the contrast into my body, and it was hooked around my left fingers to keep it in place. In my right hand I had a panic balloon in case it was too much and I needed to stop the test and get out immediately.
They put me into the machine and that was certainly an experience. I've never had an MRI before so this was all new to me.  The top of the machine was hardly 4inches from the tip of my nose, there was a bright light and a fan. I fully understand how the fan would help keep air moving and help people with claustrophobia, but for me, it just made me cold, and I am frozen at the best of times.
I had these headphones on to get breathing instructions as it was important for when they were taking the pictures. And also to muffle the incredibly loud noise of the machine.
The instructions were "breath in, breath out, breath in, breath out, stop breathing" and I was to hold my breath until they told me to resume. This was about as hard as it sounded. Thankfully when they were walking me through the procedure before we started the told me about how long each time was going to take, and it was easier when I counted as compared to me just holding my breath and having no idea when it would be okay for me to breath again. Each time it was about 23 seconds, and there was 1 longer one of just over 30seconds.  They took several pictures in this way, and each time the machine made a new and different, yet equally loud and annoying noise.
Then the contrast was inserted. This felt akin to slowly dipping my arm in very cold water as the contrast worked its way through my veins. I didnt really feel it through the rest of my body, mostly just the arm. Once the contrast was in they took another series of pictures, same breathing instructions, waited 2mins, and took the final series. The entire test took about 20minutes.
The pulled me out, unstrapped me, took the needle out, and I was free to put my red high heels on, change and leave.
How did I feel during all this? It felt like the world only existed in that small space, and I lost all concept of time. I didnt feel claustrophobic or anything like that, but I did feel nausuated and disorientated when it was finished.
It wasnt a hard test, and other than the multiple needles looking for a vein it was relatively painless. If they hadnt been running late I would have been at the hospital for about an hour.

The last things I have are a meeting with the psychiatrist (the appointment still hasnt been booked and likely wont be until May), then with a Doctor to go over all the test results and to determine which kidney they are taking, and finally on to the surgeons. How many surgeons and transplant specialists depends on if I am staying local, or if I am going to be going somewhere else in the country for the surgery.
I hope to be able to donate in this city as I dont think  I would be comfortable trying to recover in a hotel.
And as we get closer to being confirmed for surgery I am getting to a point where I am going to need to tell my boss. I havent said anything at this point, although I did tell her I was going for an MRI, and was 1 step away from telling her the full story. I told her about the MRI so she would know that some of this has been going on for a while, and wont be caught fully off guard when I do tell her. My husband thinks I should tell her the full story when I get confirmed, but I am leaning towards just telling her that I need surgery to remove a kidney and leaving it at that. I dont want any accolades or special treatment, and I know if I tell her it will be very hard for her to keep this between us. I know I need to figure all of this out, but I also know that it will be a while before I tell her as there is really no point until I am confirmed as a donor and the surgery is booked.
For now, I'm just happy to be back in regular clothes and out of the hospital gowns.
