You have never felt true pain until you've sneezed while having a nosebleed.



While wearing a white shirt.

I got shampoo in my eyes while I was taking a shower, and when that happened I got a nosebleed.

I thought my eyes were bleeding, I was scared af

The worst is when you are sleeping and get one wake up and think it's just a runny nose until you notice it's too quick to be a runny nose and you look like you just killed someone and so does your pillow case

I had a period of time where I got multiple nosebleeds a day, and I can tell you that the best way to deal with them is to pinch your nose for 2-3 minutes. Also may seem kinda disgusting, but if you happen to get a lot of nosebleeds, you can sparingly apply vaseline or chapstick to the inside of your nose. I recommend Vaniply, slightly expensive but definitely worth it.

In Denmark there is a big misconception that you should pull your head back when you get a nosebleed, Don't do that! It will just run into your stomach and make you throw up, lean forward, and pinch the top of your nose, preferably with something cold like a wet cloth or an ice bag behind the cloth :)

I often have nosebleeds so I've tried this a lot :/

I checked WebMD. We all have nasal cancer.

My nose bled so much regularly that I had to get both my nostrils closed with silver nitrate. It doesn’t happen as regularly now but I remember when it used to happen a couple of times a day and I’d have no time to shield my clothes or whatever I was next to from the waterfall. I’d also have to regularly spit out blood clots and swallow my blood back.

Crash course and SciShow upload at the same fricking time, and I have to chose between them.

I had nosebleeds all the time as a kid. Luckily, I haven't had one in years. I remember one time at recess I was standing beside and kind of behind my friend while we were playing a game. Her hand came up and ended up hitting my nose, and suddenly, my nose was gushing blood. She wouldn't stop apologizing, but I was adamant that she hadn't even hit me hard enough to hurt, my nose just liked to bleed all the time. Funnily enough, I've also had a blood phobia most of my life, but I was so used to the nosebleeds that, if the blood was coming from my nose, I could have cared less.

In my experience you can literally get nosebleeds during math class

[lahla]

When he said “or if you’re eleven from stranger things” I started internally screaming.

[Bob_Smith]

I am those people who don’t get nose bleeds

[funandlala]

2:10 The ones where it's because you got hurt sound so painful :'(

[ruler_riley]

I love how the poll is still pretty close to the actual statistic

[dave]

Because someone gave you the Long Farewells....

I have a nose bleed right now and blood it coming out of both of my nostrils and going down my throat. And every time I take out the tissue blood pours out. Praying for it to go away cause it’s been here for 15 min without stopping

[Ncraft]

I never got nose bleed in my life until now and im worried and want to know why it bleeds like everyday now

[browniesnofrownies]

I mean they can also be caused by rewinding time if you’re Max from Life is Strange

[parkjimns]

I’ve never had a nosebleed and I kinda want to have one for some reason lmao

[gazelle]

I once got a random nosebleed in class and I felt it in my nose so I exhaled quickly because I thought something was stuck in there and blood exploded everywhere and I just calmly turned to the teacher, said "im bleeding" and went to the toilet to clean it up.
