Do you mean physical pain, psychological pain, both?
(to help the people who may answer your question)
Usually this is how it is for me:
once you realize what happened, there's usually a sharp tingle around the entire body.. It's kind of like fear and shock.
And then you absorb it, and then the negative thoughts start coming in (positive thoughts are completely locked out at this point)
And then all the negative thoughts overwhelm you and then you cry or something
What happened to me:
I was 10 years old ?? and then my dad told the family that he would leave to taiwan for a couple of years (he's still there lol) and me, being really attached to my parents, immediately started crying in my room. I dropped my little sketchbook and forgot about everything else and focused on the horrible news. And I did that for like... A week.
When i experience pain emotionally/physically i get sleepy because thats my way of copping with it. For example i was under alot of emotional distress as a preteen and i ended up sleeping and drawing alot because it was the only way to get rid of it.
Or the multiple times ive had stomch aches i just go and sleep them off.
back when i had a torsion cyst and it would cause me extreme pain i would gasp first usually taking air in then fetal commences
probably when my wisdom teeth were coming in, all four were impacted and good god - nothing helps with that pain. every time it was an immediate reaction, you don't get used to that feeling that feels like someone is directly stabbing your jaw with a knife and twisting it. When it first came on I was just about to take a bite of food and I wasn't able to finish eating because my mind would just NOT stop paying attention to it.
I honestly disassociated twice while waiting to be seen at a dentist because the pain was that intense. Pretty sure I started tearing up because of it.
I was in flipflops while frying some meat. Bad idea, I ended up with a second degree burn in my right foot, I got distracted the pan moved a little and the hot oil went down. I knew some first aid so I just went straight to the shower and stayed there until it cooled off.
Worst I can remember is when I went ice skating with my dad when I was 9yrs old. I was running my hand along the glass of the rink while skating when my pinky finger got caught between two panes of glass, and I twisted the bone out of place. I just stood there for a moment, holding my finger, thinking about how much that hurt. Then went back to skating like nothing ever happened, never told anyone till years later, the bone is still funky.
Another time was when I was much younger... maybe 6yrs old? Me and my mom were at a dealership, and I was walking along a square railing outside, totally unsupervised. My foot slipped and I gouged the side of my face on the corner of the railing, leaving a huge gash in my cheek. If I remember right I didn't even notice it at first? I just thought that I bumped my face a bit, it sorta hurt, but then I walked into the dealership to see mom. The next thing I know she started freaking out cuz I was bleeding everywhere. Upon hearing this I barely reacted, it probably didn't even register for some reason.
Being someone who grew up with chronic migraines, and still has them, I have a pretty high pain tolerance. Growing up with cats, and regularly getting scratched and bitten also helped.
Insert a lot of bad words lol
Move the pan use your hands to make a path between people and go straight to the bathroom (first I thought the sink but it was my foot lol).First thing I think when I get burnt is, cold water now! lol
If I was thinking too much I would have end up with a third degree burn probably
Hmm physical pain... Well I've been hospitalized a bunch, I'd say the worst pain I've experienced is not usually a sudden thing. Like I was in a car accident, but your adrenaline gets pumped up and the situation was not noticeably painful to me, but the next day was really brutal. I guess I pulled every muscle in my body tensing up. SO the next day I woke up and tried to get out of the bed but I couldn't get myself to move. All the chemicals our body releases to get you through trauma were long gone, and i had to face the fact that my body was injured. it was just shooting pain everywhere I tried to move a muscle.
The worst physical pain to me is stomach stuff though. I'm not sure I feel comfortable describing that though.
Well I could describe the pain and the reaction right before I had my ingrown toenail operated on xD
In order for the doctor to numb my foot, he had to stick two needles of the numbing agent into my foot and it had to be in the very sensitive nerves in my feet. The best I can describe the pain was it felt like a needle shot lava into my veins.
My immediate reaction was I screamed bloody murder and cried like a child while my aunt held down my legs that were shaking hard from the pain.
The moment I saw my drunk parent taking my sibling into the car, that moment,... time didn't stood still like in those movies.. It went even faster then ever. I didn't had the time to make a plan, I had to do something And I had to do it now!
As soon as I did as my instincts said, taking my brother out of the car, I was hit with a fist full of keys sticking out, bashing into my head.
Blood was dripping in the back of my neck, but I had my siblings in my arms, the only emotion I had was panic. The urge to run, to survive. I had so much pain, but I felt none, because of the adrenaline.
For me, both with emotinal and physical pain, there tends to be kind of this... frozen distant moment. Everything goes white and I I'm just observing, and I go "oh no, this is about to hurt". What happens when it does hurt is variable. I get injured a lot, so I tend to try and make jokes and put other people at ease, but -
Most injuries, I feel sort of... angry. I think of the time I got my foot caught in a pottery wheel and slammed my knee into the tray. That's when I tend to swear and hiss and flap around trying to stay distracted and kinda laugh like an idiot. You are just trying to hold off the pain.
Head injuries really daze me. I kinda lie on the ground not really understanding what's happening. Last time I got a concussion, I just started crying. Not crying in pain. I wasn't sure why, there were just tears. I kept trying to tell people I was fine, but I had trouble talking and collapsed when I tried to move. I just sort of felt like I stayed in that floaty, shocked place.
Emotional pain tends to have a moment of shock and then "I know this is bad, but I don't feel anything". I try and think about what I should be feeling and take writing notes, but it all feels kind of fake and weird. I start planning on how to fix it and get angry if somebody tries to calm me down or get me to stay still. It usually takes me a couple of days to actually get around to the sad part.
Well, the worst pain I think I've ever been in is probably when appendix burst but... then again not really. At first I thought that I just had the stomach flu, and so did my dad and brother. We thought it would pass in a few days. We waited about three days to see the doctor.
The doctor was actually pretty shocked, saying that he was surprised I lived with a burst appendix just sitting in my gut for three days. The post-surgery hurt more then the appendix itself, I'd say. Mostly dealt with that by laying down, moaning constantly, and trying to sleep as much as possible.
For regular, every-day pain, ala banging my head on my car roof getting out, I usually hiss, say 'sweet mother hubbard' or some sort of a PG swear to that effect, and grip the afflicted area.
While I have no experience with horrific pain, I do have an idea of what it would be like.
When I get hurt, I panic. Panicking for me is a hot, tingling sensation in my limbs. My heart speeds up. I can't think properly. I feel sick from worry. I'm wroth at anyone who distracts me from my attempt to do a damage check. Exactly how angry I am is proportional to how much you are freaking out; your panicking only hinders my efforts to calm down which frustrates me.
The most recent example would be when I got in an argument ending with my head having a moment of intimacy with the wall. I gave my much larger sibling a very light backhand to the cheek (I was going for shock value, not damage). As I had anticipated, they overreacted. They shoved me hard enough for my pathetic, little self to go flying into the corner behind me. I hit my head— fortunately, not too hard— and sat there for a few seconds, trying to figure out if I was okay and yelling at my sibling to go away (and getting angrier when they ignored me so that they could soothe their conscience by doing nothing useful). I didn't actually know what I was saying, only the meaning they got across. I probably did have some tears, but more from rage than pain.
Story Time!
The worst experience where I felt horrific pain was when my girlfriend of two years cheated on me with an older woman and her kids were already calling her "Mom" meaning that she had been with her for a while and it was a mutual friend that told me what happened.
My reaction was that I was so pissed and hurt, I started to cry. It felt like someone had stabbed me in my heart and my stomach ached as if I was going to throw up. I went to my room and sat on my bed in a daze because she was the longest person I've been with. She knew she had my heart and then the feeling of hatred took over the sadness and I wanted to fight her.
I wanted to fight her because she knew all she had to do was come to me and tell me she found someone else and I would've accepted that. Who am I to keep someone in love with me? But she didn't do that. I felt like trust had been broken and she hurt me so bad emotionally and mentally, I wanted her to feel that pain physically.
However, our mutual friend told me not too. He reminded me that I was sixteen and that it wasn't worth it. She wasnt worth my time nor my love. So I took a long hot shower and prepared my mind to confront her the next day.
And thats it!
