How does your brain respond to pain? - Karen D. Davis

View full lesson: ed.ted.com/lessons/how-does-yo...
Ouch! Everyone experiences pain -- but why do some people react to the same painful stimulus in different ways? And what exactly is pain, anyway? Karen D. Davis walks you through your brain on pain, illuminating why the "pain experience" differs from person to person.

[@Goabnb94]

You can't train yourself to feel less pain, but you can build up your tolerance to it

[@Goabnb94]

Richard H I believe its the threshold of pain. Heat receptors might be activated and feel pain at 50 degrees C, but you can continually touch objects hotter and get used to them, that you still feel the 50 degree heat in the same way, but your threshold is higher and pain won't be triggered. I know this on the basis that people brought up in areas where spicy food is normal cuisine still feel the burning sensation of the food, because the spices are literally activating your heat receptors above their threshold. Its not that they don't feel the heat of the spicy food or react any differently, its that they've trained their threshold to be higher through continual use.

[@carljrrisner6957]

[@snapdragon931]

Goabnb94 So does that mean those Tibetan monks that set themselves on fire but remain completely calm have practiced by walking on hot coals first or something like that? Your opinion does make sense but I'm also with Richard in thinking it might also be mind over matter since the monks are probably meditating while their bodies are on fire.

Depends on the pain. Major cuts (sheet metal half to a full inch in the arm), broken bones (ankle and detached tendon i thought was a sprain as I don't bruise much), constant minor cuts unnoticed, or this past week a large chuck of skin scraped off my ankle that was noticed mid-healing. But a headache, migraine, or stiff/sore finger joints - it's like a red light blinking directly in front of my face. Cannot be ignored.

But WHERE is this support?😦 I haven’t found any kind of real support and I certainly don’t get it from my family. My husband just doesn’t have empathy and he just can’t relate or just doesn’t care,..he’s hard to understand actually.🤷🏼‍♀️ I have looked for support in my area but there just isn’t anything. Even psychiatrists I have searched up,..I didn’t find any who have experience with people who live in constant pain and misery. I have no one to talk to that understands. So many people have not experienced some kind of severe pain, let alone being stuck with it until death so, there just isn’t anyone. 😩

The fact that the degree of pain experienced from the same painful stimulus varies depending on a person's experience intrigued me.

Watching this video made me wonder how babies with no experience feel pain, and I wanted to learn more about it.

[@crristox]

[@gamegamer9523]

This is the source of all power. The more pain I endure, the stronger you become.

[@Jessicahasopinions]

You guys should do one about people who have pain but no injury like fibromyalgia. I would love to understand why I'm in constant pain.

[@eldetpacko7401]

Google it, maybe?

[@Jessicahasopinions]

I would and have many many times but the way they explain it makes it easier to understand

[@eldetpacko7401]

Jessica SmokeyMcPot So why wouldn't you just Google it, but then later watch the video they might make on it later?

[@YamCherie]

Jessica SmokeyMcPot There actually IS damage in Fibromyalgia, but not necessarily to the areas of the body that hurt or malfunction. The damage is in the Central Nervous System, most often caused by repeated or ongoing childhood trauma. When a child's brain keeps getting overrun with stress hormones while it is developing, there are alterations to the development. Those stress hormones keep the fight or flight response stuck in the ON position, when it is designed to activate in emergencies, for short periods of time. Eventually the fight or flight system won't shut off, or it is damaged and keeps the person's body in a constant state of malfunction. Think of an overheated electrical system that still functions, but it has surges, and some areas get too little of a signal, or an intermittent signal. Childhood trauma causes emotional pain, and so do the memories of it. Emotional pain and physical pain share the same neural pathways, and the brain cannot distinguish which kind of pain is being transmitted. The brain just knows that it's pain. These pathways get overused during trauma, and are part of the nervous system malfunctioning of Fibromyalgia. We have a sensitized pain center, and we get too many pain signals when we shouldn't. On top of this, we feel the pain more intensely. This is due to the fact that we don't release the natural, opiate strength pain reliever that a healthy person's nervous system will activate as a response to pain. If a healthy person accidentally kicks the leg of a chair, his pain will soon have a rescuer. His brain calls in the body's natural, opiate strength pain reliever to come to the site of the injury. His pain begins to dull, so that he can go on to do other things without the injury hounding him. But in a Fibro sufferer, this natural pain reliever doesn't come. So our pain keeps on and on, until our nerves are worn out and we can't think straight or move on with life. Think of having someone lightly scrape their fingernail across your forearm. At first it's no problem. But imagine if they keep scraping their fingernail across that very same spot, over and over and over. Eventually it irritates you. Then it's uncomfortable. Then painful. Finally it is throbbing so bad you can't stand it. This is the same kind of effect that happens to someone with Fibro not getting the relief of the natural, opiate strength pain reliever. The pain signal keeps coming, and it wears away on the same nerve, over and over, until it is sensitized and becomes unbearable. There are sensory nerves in the blood vessels, that feel pain. With Fibro, extra nerve bundles form, or the bundles are larger than normal. When these nerves start going haywire, we get pain all over, because our blood vessels go everywhere. The malfunctioning nerves affect the walls of the blood vessels, and that means changes in blood flow. In a Fibro brain, medical science has found areas with too little blood flow, and areas with too much blood flow. When this happens in our muscles, we get pain and we get spasms. Migraine pain is from the spasming of a blood vessel in our brain. When nerves in the digestive tract go haywire, we get changes in blood flow, we get pain, and we get diarrhea or constipation. Think about this, every area of your body contains nerves. And every area of a Fibro sufferer's body is affected by our disease. I hope this information gives you a better understanding of what we go through with Fibromyalgia.

[@givemewhiskeynow]

Pain (From Naruto): "Have you begun to understand pain?"

[@juliaguseva2335]

I noticed that the video mentioned that the endorphins released during pain are the same as the ones release during high level exercise. I am a doctor of physical therapy and I treat patients with acute and chronic pain, many of whom are afraid to move or exercise. One of the most studied treatments for pain is actually aerobic exercise due to this endorphin effect. I am always looking for educational videos about pain to send to my patients. This one came really close, but focused a lot more on medications than natural methods of reducing pain, like exercise, diet changes, mindfulness, and activity pacing. I would love to see some content that frames exercise as a treatment for pain.

I have a very high level of pain tolerance. This causes some problems, since I sometimes can't tell how badly I'm hurt based on pain and I end up hurting myself and not even noticing all the time.

[@RK-ep8qy]

Summary! We all react differently to pain depending on how we handle it - so using tasks to focus away from pain helps tolerate it. Pain is a feeling associated with damage to tissue (skin, if you like), we measure it in intensity. Nerve cells send messages and it is processed leading to our brain deciding what to do; you pay attention and endorphins are released stimulating the running away feeling to stop the pain or relieve it - how your brain processes this information decides your pain tolerance. For mild pain, medicine acts on where pain starts. Other painkillers reduce the activity or increase the number of endorphins. Some use distraction while others have taken cognitive behaviour therapy but for pain that lasts long after injury, scientists are looking at medicine that blocks messages travelling to the brain to stop pain. MRI is used to help effectiveness for the patient since we all have variability. Basically.

So I trained myself to be tolerant of pain, through playing sports, as well as playing things like airsoft, and paintball. Since I was competitive my brain snapped out of pain much quicker to focus on winning the game. We work our hardest when we're at play.

[@ValerieMorrison]

[@urex1717]

This is an interesting subject and one which this philosopher has given some thought to. My experience suggests that those who fear pain most, have had the least exposure to it. This statement is based on the notion that psychology plays a bigger role than physiology. Observation of non-human animals and personal experience play a huge roll in this conclusion.

[@FEATHEREDNEW]

If your in pain think about sex, try and get the specifics of that sexual vision, focus on the clothes of the person, how their skin feels, how good the pleasure feels. Humans have an instinctive drive for sex, that's why when we're hungry for it, we become like animals. Doing this, your body will either completely ignore pain, or significantly reduce it. It works both with pain, anxiety, nervousness, stress. Helps me all the time.

Time to test every type of pain

On the topic of pain, if its discovered how to pin point where someone is experiencing pain and a way to cause someone to experience short term/long term pain in specific targeted areas, would this then open the door to devices where you might be able to simply turn down someones pain, be able to create more affective pain relief methods, also make it so a persons partner could take an amount of pain off there partner and experience a portion of it themself, for example the man could take some of his wife/girlfriends pain while giving birth, also with the ability to cause pain in specific places in someones body it could be a test when trying out pain relief that affects certain places of your body. Another aplication of being able to cause pain somewhere on a person would be a quite effective tool for torture, interigation or a punishment for some criminals. But just imagine how amazing a device that you could hook yourself up to and be able to put a stop to any pain your feeling, the possible aplications are insane to think about, some off the top of my head is a soldier who is surrounded by enemies and if he gets shot or thrown about from nearby explosions and falling debris, he could just not need to worry about anything stopping him from shooting his enemy, another would be a propper bloody and brutal fight between two people not feeling any pain.

When I have pain, I'll do ANYTHING (except for harming others/me) to stop it. I am super sensitive (most small patches of peeled skin are 6+).

우리의 두뇌가 어떻게 고통에 반응을 하는지 배웠습니다. 메시지를 전달하는 방법이 고속도로 같습니다. 이렇게 빨리 메시지를 전달하는 것이 정말 대단한 것같습니다. 좋은 영상 감사합니다.

I work on tasks to try and lessen/ignore the pain
