Most people have experienced the painful, infuriating misfortune of stubbing a toe. But why does this seemingly minor injury hurt so darn bad in the moment?

It’s a question that actor Kevin Hart (a fellow toe-stubbing victim) recently posed to Twitter: “I swear stumping your pinky toe might be some of the worst pain on the planet,” Hart wrote. “I just don't understand how it hurts so bad and then goes away so fast...how???? Help me understand this shit please...I almost cried just now...And then it was over.”

Although it may seem like a lesser injury, when you stub your toe, there is actually a good deal of force behind the movement due to the weight of your body and your momentum converging on that tiny body part.

Here’s the All-New Medical Test That Can Pinpoint Your True Age

  Here’s the All-New Medical Test That Can Pinpoint Your True Age If you know when you were born, chances are you're aware of your chronological age. But what about your biological age? There's a test for that.Whereas your chronological age refers to the amount of time you’ve been alive on this planet, your biological age refers to how old your body actually seems (for example, Jane Fonda’s chronological age is 80, but we’d be willing to bet her biological age is closer to 45).

For most people, a stubbed toe doesn't provoke vast range of pain experiences—it just hurts like hell. Your fingers and toes obviously don't enjoy such padding. Both are also packed with nerves, specifically nerve ending receptors called nociceptors that are good at detecting actual or potential

But why does it hurt so much ? Is it because our furniture secretly hates us for making it spend the first five years of its life in an Ikea warehouse before becoming a scratching post for our cats? Lastly, Chris thinks one of the reasons stubbing your toe is so painful is due to our evolutionary progression.

“In fact, you can put two to three times your body weight on that small surface area if you’re jogging or walking fast,” Georgeanne Botek, D.P.M., who works in the Department of Orthopaedic Surgery at Cleveland Clinic, tells SELF.

Toes contain a whole bunch of nerve receptors that get struck by the blunt force on impact.

“Each digit has two nerves, one on either side,” Dr. Botek says. “So no matter where you hit your toe or how you stub it, it’s going to affect a nerve impulse from your toe to your brain.”

This nerve impulse is modulated by sensory neurons called nociceptors, which fire off information to the brain whenever they sense an external stimulus that may cause harm to the body. That includes extreme heat or cold, certain chemicals that could burn the skin, or mechanical pressure that could damage the tissue (like the force involved when you bang a toe into the hard foot of a chair, for instance).

Want to Be Happy? Science Says Don’t Try So Hard

  Want to Be Happy? Science Says Don’t Try So Hard A new study published in Psychonomic Bulletin & Review says that people who try too hard to be happy end up achieving the exact opposite. Everyone wants to be happy, and yet happiness can often be difficult to achieve, in part because we’ve been taught very misguided notions of what it takes to attain lasting emotional well-being. For example: people often assume they’d be happier if they just had a little more money, but studies have found that, after you’ve reached a certain salary, your happiness actually declines due to stress and lack of leisure time.

Anyways, why does it hurt so much ? I can handle like shots, a piercing, going head first into a wall, etc. but when I stub my toe ! . yikes.

" So Much " is a 2010 single by Indo-Canadian singer Raghav featuring Canadian hip hop artist Kardinal Offishall and produced by Labrinth from Raghav's third album entitled The Phoenix. But it turns out, there's a good reason why stubbing your toe hurts so much .

“When that specialized neuron gets activated, it fires, sending that information to the spinal cord,” Jeffrey Mogil, Ph.D., a neuroscientist and professor of pain studies at McGill University, tells SELF. From there, the information is processed by the brain and, eventually, you perceive it as pain.

There are two separate waves of perceived pain: the immediate, sharp “ouch” followed by a lingering, achy sensation.

The nociceptors, which communicate via thick, insulated nerve fibers, transmit the sensory information to your brain “essentially instantaneously,” Mogil explains. This is the first pain response you’ll feel—a sharp, intense discomfort that might make you yelp a four-letter word.

Then there are thin, uninsulated nerve fibers that fire more slowly and produce what’s called second pain, which is a duller burning sensation that lasts a bit longer. “The lag between first pain and second pain can be half a second or a second,” Mogil says. Additionally, your pain reaction may be associated with an emotional response, like frustration or anger.

I haven't stubbed my toe in a while, but I remember how much it would hurt ! Btw the ahhhh part was from "The Earth Song", by Michael Jackson. Why Stubbing Your Toe Hurts So Much - Продолжительность: 3:03 Science Insider Recommended for you.

How about why stubbing is so much more painful when your hands/feet are cold? posted by DU at 10:16 AM on August 4, 2012. And why is this stuff coded to my reptilian brain and yet I can't remember the name of the person I met five minutes ago? Because that person isn't going to kill you.

While it can be unpleasant, this pain response is actually a reminder that your nervous system is working properly to help protect you from harm. In general, pain functions as an alert system telling you to stop whatever it is you’re doing that could potentially cause tissue damage, like grabbing a hot pan with your hand. But it’s not particularly useful when you stub your toe, Mogil explains, “because in that case, by the time you feel it, the damage is already done, and it’s too late to avoid it.”

The anatomy of your toes also makes them particularly vulnerable to injury.

”When you’re stubbing your toe, you’re hitting not only those nerves, but also the skin, the nail, and the bone,” Dr. Botek says.

In most cases, your pain will go away after a few seconds or minutes. But if not, that’s a sign that something more serious has happened. For example, your toenail “can act like a piece of glass on your skin and cause damage to the skin itself,” she says. In other cases, the nail bed might get bruised, causing bleeding under the toenail.

Also, the bones in the toe are relatively unprotected. “You don’t have a lot of fat pads on your toes, like on your abdominals or buttocks, so it’s a very fine diameter between the tip of your toe and the bone,” Dr. Botek explains. Because the bone is not well-cushioned, you can get a bone bruise, she adds, which can cause serious pain that lasts for several weeks or months without any visible injury on the outside.

Want beach-ready abs this summer? These are the exercises you need.

  Want beach-ready abs this summer? These are the exercises you need. Having great-looking abs takes time, dedicated training, cardio and eating clean meals.Great abs, therefore, begin first and foremost in the kitchen. It's important to try and cut out fried foods, sugars, refined and processed foods, alcohol, and even dairy (dairy is high in fat). That means eating more natural foods like vegetables, fruits, protein (such as lean meats), lentils, brown rice, whole grain breads, nuts, and drinking lots of water.

And, of course, you can also break your toe if you stub it hard enough. In that case, you might notice extremely intense pain, black and blue discoloration, swelling, and misalignment. “If the pain is a persistent 10 out of 10 for more than a few hours, then you should get it looked at,” Dr. Botek says.

But, a lot of the time, a stubbed toe is just that. It hurts like hell, but just for a little while.

The Way You're Sleeping Could Be Killing Your Lower Back .
There are really only two ways you should snooze. Sleep is supposed to be rejuvenating-so why do you wake up so stiff all the time? Simple: it’s because you’ve just spent eight hours in one position, says Andrew Gitkind, MD, medical director of the Montefiore Spine Center. That’s why it’s so important to sleep in a position that won’t aggravate any existing aches, especially if you struggle with lower back pain, says Jennifer L. Solomon, MD, board certified physiatrist in physical medicine and rehabilitation at the Hospital for Special Surgery.
