they can cauterize your blood vessels in your nose, which will help prevent nosebleeds.  My brother gets them a lot, because we live in the desert, and the air is really dry.  One thing that helps is if you put a Q-tip into a jar of Vaseline (or maybe put Neosporin on it) and then swab the insides of your nose every morning and night.  It really helps.  I used to get nosebleeds a lot when I was on a medicine called Accutane (it dries your whole body out really bad -- it's for acne), and I used to do that.

Many people have had this problem, at least transiently.\n\nYour body is an adaptable mechanism.  It will adapt over time to various stresses that cause problems.\n\nSome that can cause a nosebleed are:\n\nTemperature -- mostly hot, but sometimes cold\nPhysical activity beyond the usual\nColds and allergies\nHigh blood pressure\n   combinations of the foregoing\n\nPersistent nosebleeds are a different matter.\n\nAre you eating your veggies?\nDo you have low Calcium?\nIs there some other medical condition of which this is a symptom?\n\nIf your problem persists with an adequate diet, then you need to ask your doctor about it.\n\nThere are some simple laboratory tests for starters, but all cannot be explained here and is best judged by a competent professional.\n\nIf you want to know more about the medical aspects of epistaxis or nosebleed, start with the Merck Manual for physicans which you can find in any major or college library.\n\nOr go to http://www.webmd.com \n(even more convenient) and search under nosebleed or epistaxis.

S'not funny, is it? It's why most people get nose bleeds when they have colds, cos they bust blood vessels trying to get at stuff which isn't there.

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.

Brain haemorrhage is bleeding on the brain.\n\nThis is one of the causes of a stroke. About 80% of strokes are caused by a blood clot rather than bleeding.\n\nA common cause of brain bleeding is a weak or thin spot on a brain blood vessel.These weak spots stretch out and can rupture. \n\nBrain vessels that have become brittle because of hardening (because of high blood pressure) can also break open. \n\nAnother cause of brain haemorrhage is the presence of a tangle of blood vessels within the brain that have thin walls and that can burst easily.\n\nBrain haemorrhage can also happen due to a blow on the head and older persons or those with brittle arteries are more likely to get a brain bleed from minor bumps.\n\nSymptoms due to brain haemorrhage can start quickly and without warning (most cases) or slowly.\n\nWhen any of these symptoms occur, a brain haemorrhage could be present and emergency medical attention is needed:\n\nNumbness or weakness of the face, arm, or leg, especially on one side of the body. \n\nConfusion, trouble talking, or understanding speech. \n\nSudden trouble seeing in one or both eyes. \n\nSudden trouble walking, dizziness, or loss of balance or coordination. \n\nSudden severe headache with no known cause

Nosebleed\n\nWhat is a nosebleed? \nA nosebleed occurs when the membranes lining the inner nose are disturbed or irritated enough to cause abnormal bleeding. The medical term for nosebleed is epistaxis. \n\nThere are 2 types of nosebleeds: anterior and posterior. If the bleeding is near the front of the nose, it is an anterior nosebleed. If the bleeding is from the back of the nose, it is a posterior nosebleed. An anterior nosebleed is usually not as severe or serious as a posterior nosebleed. \n\nHow does it occur? \nThe most common causes of nosebleed are: \n\nA breakdown in the membranes lining the nose. This can be triggered by dry air or probing, bumping, picking, or rubbing your nose. Blowing your nose forcefully can also cause a nosebleed, especially if the nasal membrane is already inflamed because of allergies or an infection, such as a sinus infection. \nInjury to the face or nose. \nRebleeding from an area of a previous nosebleed. \nHigh altitude. \nDrug abuse involving the nose, such as cocaine snorting or glue sniffing. \nHigh blood pressure. \nMedicine that increases the time it takes for your blood to clot. \nMedical problems that prevent your blood from clotting normally. \nIf you have a nosebleed after a heavy blow to your head, it could mean you have a fractured skull. You should go to the hospital right away. \n\nWhat are the symptoms? \nSymptoms of anterior nosebleed are bleeding that stops and starts or constant bleeding out of the front of your nose. Blood can flow from one or both nostrils. It may flow into your throat. \n\nSymptoms of posterior nosebleed include rapid bleeding from the back of the nos or a slow, steady ooze. Sometimes the blood flows back into your throat and you are coughing up blood. It is more common with posterior nose bleeding to lose blood quickly. \n\nHow is it diagnosed? \nIf you see your health care provider when you have a nosebleed, he or she will have you sit up and lean forward to determine the rate and site of the bleeding. Depending on the amount of bleeding you are having, your provider may check your pulse and blood pressure and take a blood sample to check for anemia. You may need tests to check the ability of your blood to clot and your blood type in case you lose too much blood and need a transfusion. \n\nHow is it treated? \nMost nosebleeds are minor and respond to first aid. First aid for a nosebleed includes these steps: \n\nWhen your nose starts bleeding, sit up and lean forward to prevent blood from passing into your throat. \nPinch the nose firmly together between the thumb and index finger, just below the nasal bones, and hold it for 5 full minutes. \nIf it continues to bleed, hold it again for another 5 minutes.

Not always!! In a few cases, hormonal imbalances can lead to sinusitis.\nDisease, unmanaged mental or physical stress, and hypothyroidism can cause hormone fluctuations in estrogen or low thyroid levels, occasionally leading to nasal membrane swelling and sinusitis.

Rupture organs, ulcers.\n\nGo to the ER now.  It's a very serious thing to be bleeding internally.  It's worth it to go to the ER, or an Urgent Care clinic, or any other clinic right now.

Along with what the others said on sinuses and the like, I'd like to point out that often cold weather accompanies dry weather. (as there is less H2O in the air when it's cold because of less evaporation and so on)\n\nSo, that air low in humidity may "dryen" the inside of your nose, wich is meant to be humid, thus causing pain and maybe even bleeding. The same as your lips get cracky and dry in winter time. \nAlso, the blood vessels in our inner nose tissue are somehow fragile. Breathing really really cold air may "burn" them by the cold a little, and thus the pain.\n\nI'm not an expert tough, but maybe a good scarf could improve things up! :)\n\nIn any ways, good luck with your problem! ^_^

There are several potential causes.  First, depends on how long its been a problem.  Potential causes are : gastro-esophageal reflux; chronic sinusitis with resultant post-nasal drip, an ENT specialist should be sought to see if the sinus drainage is caused my mucosal irritation due to a nasal or sinus polyp which should be surgically removed if found.  Also, some anti-hypertensive medications can cause chronic cough - such as ACE inhibitors ( a very common cause of chronic cough)

IT ALL DEPENDS ON MANY FACTORS. NOSE BLEEDING OR EPISTAXIS AS IT IS CALLED IN MEDICAL LANGUAGE,MAY BE DUE TO SEVERAL REASONS. THE COMMONEST CAUSE IS CONGESTION IN THE NOSTRIL AREA DUE TO ANY INFLAMMATION SAY DUE TO COMMON COLD.BUT IF ONE BLEEDS OFTEN, HE MUST HAVE HIS COMPLETE BLOOD TESTS DONE. IT MAY JUST BE DUE TO A BLEEDING DISORDER.WHICH NEEDS URGENT TREATMENT. ANOTHER VERY COMMON RESON IS ELEVATED BLOOD PRESSURE.THAT IS A BIT BENEFICIAL TOO AND HELPS IN REDUCING THE SUDDEN ELEVATION IN BLOOD PRESSURE BEFORE IT CAN DO MISCHIEF IN THE BRAIN.BUT ONE SHOULD NOT RELY UPON THIS NATURE'S MECHANISM OF REDUCING BLOOD PRESSURE. BLOOD PRESSURE IF ELEVATED SHOULD BE TREATED PROPERLY AND KEPT IN CONTROL.WELL I DO THINK YOU OR THE PERSON HAVING THIS PROBLEM SHOULD IMMEDIATELY CONSULT A DOCTOR.

Apply an ice pack to the back of your neck.  You can also apply direct pressure to your nose.  To prevent a bloody nose, you should sleep with a vaporiser, or humidifier in your bedroom, to keep the inside of your nose from getting too dry.
