I once had a right heart catheter through the crook of the arm. It was the most bizarre thing I could imagine as after a few minutes I realized something was wrong. They asked me to cough. Then, to cough again. I asked them if they were stuck in the armpit, which they admitted. Then I realized I was meant to do an exercise ekg with the catheter (which had finally reached the heart by now). So... I was lying on my back with this green plastic blanket on my upper body, a wire in my heart and had to kick the pedals which had magically shown up in a gap of the cot. And if that wasn't enough, the wire from time to time collided with parts of my heart. And you are simply not used to any mechanical contact of the heart with something else so it was a strange feeling. Shortly afterwards the cardiologist who ordered all this retired and none of the cardiologists treating me since ever understood why this check was performed at all. So I guess it wasn't worth it, but for the story.

And: I only had one gastroscopy so far. Everyone told me before how disgusting the procedure is so I was beyond scared. The doctor told me he was going to sedate me. In my language, sedation is nicknamed "scheißegalspritze" "I-don't-give-a-f*ck-injection" and that basically summed it up. I didn't care what they did, I was half asleep patiently listening to my own choking (as IDGAF). Afterwards I had a long nap in the wake-up-room. Then I was placed in front of his office in a big chair to be told the results - next nap opportunity gladly taken. Then my brother drove me home. He asked me how it went - had to wake me up for the answer. 10/10, would do this again anytime :D
