Actual organ shutdown stuff, yes. Once following a car accident, the ambulance and the ER fixed that up. The other time was during a heat stroke incident as a teenager. I don’t remember much of that one. My impression is that time was much more serious.
Two months before I turned 5, the apartment building my family lived in caught fire in the middle of the night and we had to rush out. I went into shock, and was taken to the hospital by ambulance…but by the time we got there, I was fine.
I had a bad fall while running last year and injured my shoulder.
It didn’t hurt terribly, but I definitely couldn’t raise my arm and I had difficulty doing simple things like getting my phone out of my belt pouch to call my wife.
My fear was that I torn some important soft bits.
After she came and brought me home I realized that the shoulder was tightening up and not improving, so I asked her to take me to the hospital.
The place was busy and I spent quite a bit of time in “hurry up and wait”. A nurse asked me “What’s the pain level on a scale of 1-10” and I honestly said “Maybe a 2” since everything above 5 is reserved for dental pain, compound fractures, and maybe kidney stones (never had one).
About an hour and a half into the ER visit I began to sweat profusely and my legs were shaking uncontrollably. My wife was very surprised and she said I was pale too.
That sensation was unfamiliar–I assumed it was something akin to “going into shock”, but figured that somebody would be by and notice and do something if it were really a problem.
The nurse stopped in ten minutes later to tell me I had a fracture in my shoulder and she offered me something more useful than Advil for the pain as she strapped on a sling.
I had a pretty nasty vasovagal reaction when having a horse syringe of Synvisc injected into my ankle joint capsule. Had to lie down for a little while in the exam room, but I wanted to get home, so I probably didn’t wait long enough and tried to hobble down the hallway with a cane. Then I had to lie down on the floor with my feet up for a while. I really wished the ortho’s office had warned me to bring crutches.
I stupidly tried to beat an ambulance into an intersection. Got t-boned but thankfully everyone was fine. I spent the next half-hour alternately crying and laughing. It was a quite disturbing memory.
Pretty sure I was in shock after I got run down on my motorcycle. They were yelling at me in the ambulance to not fall asleep.
In my late teens, I developed an ingrown toenail, and my home remedy turned it into a red, swollen, infected mess, such that I finally went to a Podiatrist to deal with it.
The Podiatrist tried to go in and chop it out, but the toe was so tender that the pain was excruciating, and I went into shock; cold, clammy sweat, shortness of breath, the whole nine yards. Almost passed out. The nurse walked in, took one look at me, and ripped a strip off the Podiatrist’s ass right there on the spot, even as she was treating me for shock.
The podiatrist finally hit me with local anesthetic until my toe was numb enough to do his thing.
I’ve been stumbling around in normotensive (normal blood pressure) cardiogenic shock for a number of years now.
I’d say that it gets good to you, but … meh … not so much 
Yes, it was due to severe physical trauma and loss of blood. I was told my blood pressure in the ambulance was 80 over 40. Somehow, I hung on and eventually came back.
Glad you’re still here with us. This sounds sub-optimal.
Twice.
The first time, I was walking my dog while wearing a winter coat. Squirrel happened, my dog lunged unexpectedly, and I went ass over teakettle, landing hard on my elbow. It hurt, but not terribly. I finished walking my dog, got home, took off my coat, and I had blood running down my entire forearm. Apparently, when I fell, I landed elbow-first on a particularly pointy bit of road gravel, which left a surprisingly deep hole in my arm - deep enough that when I found it while washing the blood off, my knees started to buckle and the lights got dim. Some deep breaths and a bit of sitting got me through it.
Second time was after I back-hand slapped a cactus. (Not on purpose. I was gesturing emphatically, and didn’t notice the spiny bastard just behind me.) Got a cactus spine right in the knuckle of my left ring finger, which immediately started swelling, because the apparently that species of cactus also produces an irritant on its spines. Hurt like a son-of-a-bitch. Figured I get some aspirin, see if that would help the pain and inflammation, but I didn’t have any in the house. I did, however, have a plastic bin full of medical stuff left over after my dad had died the previous year. Figuring maybe there’s be a bottle in there, I pulled it out from under the bed, grasped it firmly by both handles and lifted it on top of the bed - completely forgetting about the injury in my knuckle.
Soon as the pain hit me, I had tunnel vision. In my shocked state, I thought I was having an anxiety attack, and tried to grab my meds, but just as I got the safety cap open, the tunnel closed and I passed the fuck out. Luckily, I apparently hit the bed and then slid to the floor, instead of doing the full face-plant onto the hardwood floor.
My friend who was visiting heard the thump, and found me spread eagled on my bedroom floor, surrounded by scattered pills.
M for metastable, actually. Technetium 99m has an excited nucleus, and decays with a half-life of about 6 hours to technetium 99. It releases energy primarily by the emission of a gamma ray, which is what they use to image you. Regular technetium 99 decays over the course of hundreds of thousands of years, and has no particular use that I’m aware of.
As far as shock goes, while mountain biking I was traversing a hill and the trail took a sudden turn down the hill. I knew that there was a small drop, but the turn was more abrupt than I thought, and on to a steeper hill. I went over the bars, fell about 15 feet, and landed on a slab of bedrock. I landed on my hands with enough force that my left radius smashed into my humerus, knocking off a chunk of humerus at the elbow and displacing it 3 mm. I didn’t pass out, but the first time I tried to get up I got clammy, nearly threw up, got very dizzy and had to sit back down very quickly. Took me about 30 minutes to get up, and probably 30 more minutes to walk 1km to the highway and flag down someone to let me borrow their phone. Not an enjoyable experience, and I now make a point of always bringing my phone with me biking. I managed to entirely avoid hitting my head on the ground - my helmet didn’t even have a scratch on it - so all things considered I think I was pretty lucky.
I’ve fainted once in my life. I had bronchitis and fortunately had taken the day off from work because as I sat at this desk I started coughing and I couldn’t stop or catch my breath. I don’t remember what happened next, but I slowly came to on the floor, having tipped over my chair and dropped the keyboard onto the floor.
Until that very moment I didn’t understand that fainting is not like sleeping, at least not like waking from sleep. You come to much more slowly. At first I thought I must’ve gone to bed and was lying by the wall, but when I figured that was wrong a few seconds later, I realized that what I’d taken for the wall was actually the side of the old-fashioned sewing bench I keep my mouse on, and I was about 2" from breaking my nose so I’d really lucked out.
As for the other type of shock, where your blood pressure drops and all, my mom, who’d been a nurse when I was a baby, thought I was shocky once. My brother’s beagle had what we thought was a large pimple on his ear, and kept shaking his head like it was really bothering him, and we dragged him into the bathroom to see if we could see what the heck it was under the best lighting in the house. Turns out it was more of a blood blister and burst, and as he continued shaking his head, blood arched across the bathroom. Like, a lot of blood.
I’m not good with blood.
Poor mom said she didn’t know what to do because the dog was still bleeding and would need a vet visit, and I’d turned as white as a sheet so she was worried I was going to pass out and whack myself on a vanity or toilet. Fortunately I rallied enough to listen to her instructions to sit down before I fell down.
I forget exactly what the vet said the blood blister was (something about a pocket developing between layers of tissue?), but he’d probably developed the injury with his habitual head shaking. It healed up ok.
