Usually airplane cabins have a very low humidity and a fairly cool temperature. The cool dry air means that the delicate capillaries in the nose become very brittle and fragile, and break easily - particularly if you're already prone to nosebleeds. High altitudes can cause nosebleeds too. So OP was probably suffering from one of those, nothing serious.

#1 It probably doesn't normally do that, but she just stopped nosebleeding so the sneeze started it again.

1 - I disagree, as the bleeding tissue clots off, a thin layer prevents the bleeding. A strong pressure like sneezing will disrupt that layer and cause it to bleed. Nothing serious or surprising there.

Her nosebleed predicament is fairly common. And sneezes are what 100+ mph?? Yeah, I'd expect a sneeze to make a nosebleed start up again.

Over 100 mph? I think you are exagerating. I don't think a sneeze is THAT powerful.

41- actually you'd be surprised.

Pffft, MythBusters busted this!

Actually after I've had a nosebleed sneezing and/or blowing my nose can sometimes re trigger one..although the fact op's lasted 3 hours concerns me a bit...

Thumbed down you because of your name..

If I sneezed after a nosebleed that would happen, I don't think op needs to see a doctor for that. On the other note, I would suggest op seeing a doctor for cauterization. It definitely helped me.

74- I personally don't have a problem with them but if they're on FML they probably should know this is the last place to express it. It's for their own good.

If they are on a plane, there isn't a box of tissues!

He could bring some.

23 - I think Ella's a girl.

It was probably because of the high altitude.

OP is probably sensitive to high altitudes. That seems to be the most logical explanation.

It's from all the recycled air you breathe and how f-ing dry planes are. Next time bring some Sudafed and nasal spray. Got keep those nostrils moist! I should know, I've been on a lot of transatlantic flights.

Random nose bleeds are the first indication that OP has been infected with the zombie virus. The best course of action would be to jump from the plane so as to prevent infection of other passengers.

69- It's happening. Check out what went down in Miami this past Saturday. You can't make this shit up: http://www.examiner.com/article/police-shoot-naked-cannibal-during-zombie-attack-miami OR http://miami.cbslocal.com/2012/05/26/miami-police-confrontation-men-leaves-1-dead-1-hurt/

78- Was about to reference that myself but I didn't know how many people knew about it. And there's a thumb up for you.

Nah, it's probably no big deal. It happens. Also this was in a plane and I heard something about the pressure being bigger when that high up. Might have something to do with that.

I have 2-3 hour nosebleeds around when the seasons change, it runs in my family. Some of us get our noses burnt to stop it. It just happens because of the humid/dry area where we live.

Acually 29, the pressure is weaker in high altitude. It is stronger on the ground and deep under water.

My nose bleeds are short but massive .. I go for 10 mins of heavy flow lol... But its like every other month... Doctors have no explanation... (i live in miami btw.. Didnt know if that helped anyone explain my problem if they had an explanation)

A heavy flow and a wide-set ******? Your the girl from mean girls aren't you!

I dont think i said i had a ******.... Joke is invalid ..

Touchy

How did we get from nose bleed stories to wide set vaginas? I think this is all getting a bit out of hand fellows

Mean girls

I see what you did there.

In this case it's closer to bloody heaven...

It really works!!

I beleive it's best to avoid looking at a bright light and push as hard as you can on the spot right under ur nose

I've been told that repeatedly saying the word "pineapple" helps, too. However, it never works when I really need it too, like during an emotional moment in church, or during an orchestra concert... that I'm playing in.

I hate that ad. The little girl annoys me to the ends of oblivion.

^ Can't be any worse than this: "Head on; applied directly to the forehead". I swear I wanted to throw my remote through the television every time I saw that.

Gesundheit* I can't believe no one else has corrected this. It's German for "health".

No, but the people above you did.
