I get fairly frequent nosebleeds during the winter, mostly because, in the winter in the high desert, there’s slightly less humidity than there is in the Sahara desert. I can deal with that: it’s incredibly gross, yes, and immensely disturbing sometimes to wake up with blood smeared across your face, but I can deal.
Right now, my nose is gushing blood for the third time today. Part of it is that I’ve got a cold and you know how you’re not supposed to blow your nose for a half hour after a nosebleed? I keep sneezing, which does not help, and not blowing my nose isn’t really an option. this is absolutely ridiculous: I’ve gone through what must be half a box of tissues this afternoon alone: right after math class, then right after dinner, and then, a few minutes ago - hey, I’m dripping blood again! And soaking through five friggin’ tissues and counting. I want to keep any moisture possible in the air in my room, so I don’t have my space heater on, so it’s cold. I really, really don’t want to have to drape an icepack across my nose, because that will make it colder.
(Only reason I’m sharing this is because I have to whine to someone and don’t want to go roaming the dorm in my pajamas with a tissue jammed up my nose.)
You have my sympathy, and I’m really happy I can give it without looking at you with the bloody tissue hanging out of your nose.
On a practical level, I suggest you get yourself a humidifier and run it by your bed at night. You can also smear a little petroleum jelly inside each nostril. My kids’ pediatrician also advised me to give them vitamin C in the winter to help prevent nosebleeds. I’m not sure if there’s actual science behind that recommendation, but we do it anyway, just in case it actually does help.
Oh, hey, this happens to me sometimes. For no reason at all, I just would get a nosebleed - and not just a drip, but a steady flow, which would last for a good long while. And then i’d get it two, three times more that day, sometimes even again the day after. And then they just…stop, really. There is a more humid atmosphere here, though.
Instead of an icepack, you could try just a damp flannel (handcloth, whatever you call it there) draped over it - not as cold, and that seemed to work for me (but like I said, sometimes they’d just stop on their own).
I don’t really have any helpful advice…they just tend to stop after a while, really. You might just have to wait them out, i’m afraid. 
Do your laundry and hang it round your room to dry - that helps with the humidity tremendously.
Ah, the joys of persistent nosebleeds. Mine get progressively more frequent and longer-lasting until I can’t stand it any more. Then I go see the ENT specialist and get my nose cauterised. Yay!
This solves the problem for a few years. Repeat ad infinitum.
So far my best-ever experience has been with an electric cautery iron (like a medical soldering iron) applied after spending 10 mins with some cotton wool soaked in cocaine/adrenaline mix up my nose. Felt nothing, heard cool sizzling noises, got to blow out blue smoke smelling of burnt nose. Unfortunately, mostly I just get the silver nitrate sticks and no analgesia. Boooooo :mad:
Anyhow - get thee to an ENT specialist and order him/her to make it better.
Popsicles.
Sucking on popsicles (or anything else icy you can ram into the top of your mouth) will help slow down a nosebleed almost as quickly as an icepack and is less chilly on the face regions.
I prefer grape myself.
scribbles notes
I must say, I like the popsicle thing a lot better than the nose-smoke thing.
You can redirect sneezes by pulling up your soft palate and sort of locking your mouth open. It seals off your sinuses and it becomse a weird cough instead.
Yeah, but the nose-smoke thing (or alternatively the silver nitrate giant corrosive matchstick thing) prevents nosebleeds altogether, rather than just helping to slow them down. If I was, f’rinstance, giving a presentation or doing some shopping, I’d rather not have a nosebleed at all than have to whip out a popsicle.
As an added bonus, you may get a videocamera shoved up your nose to check out your sinuses! How’s that for a deal?
In all seriousness, persistent nosebleeds can be caused by anything from sensitive mucous membranes to weak blood vessels (my problem) to growths/polyps/tumours/hemophilia/other nasties. Go and see a specialist just to find out what it is - no need to accept whatever treatment they offer, but at least get a diagnosis. You’d feel pretty silly if you find out ten years from now that a simple vasoconstrictor spray twice a day would have prevented the problem.
