Dislocated shoulder. <ouch>
A little over two years ago (or was it three?), I was in the bathroom early in the morning. All of a sudden, I was incapacitated with lower back pain on the right side. I fell to my knees (no lie), and held out as long as I could (20 seconds? 30?) before bellowing like a prodded cow.
It went away about as quickly as it came, and it never returned. I always assumed that I had passed some sort of stone, or that I have one in there that's in limbo. The only other thing I could ever come up with was a slipped disk that needed to get comfy again (not very likely).
WhateverTF it is, I hope it never comes back.
We were working a medical call one night, and it wound up being a mid-50's, retired Marine with stones. He was sobbing. He told Kim (our EMT on duty that night) that he had to urinate badly. She took his vitals and let him try to pee on the side of the road.
He couldn't use the restroom, because he was 'blocked.' :-(
I never had to pee so bad in my whole friggin' life as I did when he said those awful words: "I can't. It's like it's blocked off or something."
He eventually decided that the ambulance wasn't getting there fast enough, so he took out walking. He wound up lying in a ditch until the unit got on scene.
