Why do my nose start bleeding without any reason?

It is simply a change in blood pressure.  It happens always for a reason, in other words there is always a cause.  Ordinarily, most times however, it is natural and good because it is a release of blood pressures.  Better that than blowing a hole in some internal area or something.

Cocaine is about the most potent vasoconstrictor we know of (i.e. it causes blood vessels to constrict and dramativally reduce the blood flow to the tissues in the nose). The nasal mucosa and ultimately the cartilage consequently are starved of blood (and hence oxygen and other vital things) which causes them to die off in a process called ischaemic necrosis. This eventually breaks down and leaves a perforated nasal septum (the wall in the middle of the nose) a.k.a Daniella Westbrook

Never lean your head back as this will cause blood to pool into your sinus cavity. Get some ice and wrap it in a teatowel, or even use the old frozen vege packs and wrap it in a teatowel. Move your head gently forward, get tissues and hold your nose gently near the nostrils, then put ice pack over your nose. It may take up to 15 minutes to stop bleeding entirely, if not see your GP. Don't get up and move around to much for at least an hour afterwards or go near anything hot as it will dilate your little vessels that burst in there and you'll have a nose bleed all over again. Causes may be from hitting it, picking it, heat, change of temperature, medication or change in medication, season's changing, PMT. Well hope you get better soon.

It may be a nocebo, everyone's nose either clogs or runs after crying, but if you relate it to allergies the nocebo effect kicks in and you THINK you are allergic to something, and thus you "are" :P

My nephew get's bloody noses a lot and i used to as well. A few reasons for it happening suddenly could be that their nose is dry (inside) and irritated. It could mean that a cold is on it's way. I read that bloody noses could be the result of a Vitamin C deficiency. A nurse once told me that you shouldn't have to worry about sudden nose bleeds unless they go on for more than about 20 minutes!

Very likely a mask squeeze. As you descend, you have to allow a little air into your mask (through your nose). If not it will be pressed tightly against your face as a relative vacuum is generated between the outside water pressure and the partially equalized pressure within the space enclosed by the mask. This can cause small vessels to rupture leading to bruising, black eyes, ruptured vessels of the sclera of the eye and nose bleeds.

The question should be: what did you change recently?\n\nThere are a couple of things that can have this temporary and usually innocuous effect...\n\nIf you've changed your diet or exercise routine recently. Changes in blood pressure could be responsible.\n\nAlso, altitude changes will almost certainly cause this. If you recently moved and your new location is significantly lower or higher then you may see significant blood from either nostril.\n\nMy advice would be to closely monitor the situation and if it doesn't clear up or gets significantly worse then see your doctor.\n\n--\nsf

I am a martial artist and a boxer and I have had my share of broken noses. First you can have a broken nose and not have it bleed, but it will swell up amd it will bruise. Now a good way o find out if it is broken... now bare with me, is to put your pinky fingers up the nasel passage and feel for any miss placement. This may hurt but it is the best way to find out on your own.\n  But you should go see a doctor because the is a chance that it could swell up more ad cut the air way through your nose.

Hi there !\nThe casuse for "nose bleed " or "epistaxis" are many...Some of the major ones are as follows ..\n--nose picking habit !\n--Injury in some form\n--allergici rihinitis\n--sinusitis\n--Leukemia \n--last, but most important "Haemophilia and similar Blood diseases" !\nThough it is important to find out the cause, more stress should be given to the aspects of "prevention" and "treatment", as it occurs at very odd hours in majority of the occasions !\nThe prevention includes, cold sponging, appying slight pressure over the nasal area and to come out of the "habit of nose picking" etc..\nIf it recurs, consult a GOOD ENT surgeon..!\nMaybe we have to rule out causes like haemophilia or other Blood disorders ! especially in males ! \nBest wishes !

First identify the cause.  If you are hypertensive, you have to control your blood pressure.  If the environment is warm, you have to stay in a cool place.  Press on the area just below the nostril, near the angle of the nose, to stop the main supply going to the Little's area, the source of the nose bleed.  You don't have to lean your head back, this only redirects the blood to the posterior pharyngeal area, and may just cause you to aspirate.  If bleeding persists or is recurrent, you will need a doctor to do nasal packing and eventually cauterization of the site.

I wouldnt say its "normal", but you prolly wont die ;-) you might have a blockage. have you been sick reciently or had a sinus infection? Has it been like that for a long time or did it just start. Is it only at night (or when you are laying down)? You really need to go to the Dr. and have it checked out.

Stop using it and ask your doctor.  That doesn't sound normal.  If Nasonex is for clearing your nasal passages, it wouldn't make sense for it to clog them up with blood.

Are you using a nasal spray ?\nIf yes, the taste could be from the spray that drops back to the throat.\nIf not, it could be a post-nasal drip of mucus from the nose. Check also to see if you nose is bleeding since you 'blew your nose real good' an hour ago. This may damage the nasal membrane and causes nose bleed and the blood can drop into the throat.\nGargle with water may help.\nIf you cold does not get better soon. Check with your doctor.

Um, the first answer is completely wrong.\n\nTo stop the nosebleeds when they happen, pinch the top of the nose, DO NOT lean the head back, hold a cool rag or better yet a piece of ice under the bottom lip.\n\nGo see your doctor to keep it from happening all the time.

You don't mention if something happened to your nose.\nHave you been mashing zits?  Have you been snoring coke?\nHave you had a fight and got your nose clobbered?\nSometimes a person can sleep funny and their nose gets mashed up against a pillow or on the bed and hurts the following day.\nIs your nose dry because of the weather?  Do you have cold sores around your nose making it hurt?    Petroleum based products used inside the nose will help to relieve dryness.\nHope I have helped some but without knowing what is going on,it is hard to properly answer your question.
