Are You Sick?

Nosebleed

Nosebleeds happen often because of the rich blood supply of the nose. Common causes include:

Spontaneous Nosebleed. Most nosebleeds start with no known cause.
Rubbing or Picking the nose is the most common known causes. It's hard to not touch or rub the nose.
Blowing the nose too hard can cause a nosebleed.
Sinus Infections. The main symptoms are lots of dry snot and a blocked nose. This leads to extra nose blowing and picking. The sinus infection is more often viral than bacterial.
Nose Allergies. The main symptom is a very itchy nose. This leads to extra rubbing and blowing.
Dry Air. Dryness of the nasal lining makes it more likely to bleed. In the winter, forced air heating can dry out the nose.
Allergy Medicines help the nasal symptoms, but also dry out the nose. It may cause a nosebleed.
Ibuprofen and Aspirin. These medicines increase the bleeding tendency.
Cocaine Use. Frequent use of cocaine can lead to nosebleeds. Long-term use can cause a hole in the septum of the nose.
Bleeding Disorder (serious). This means the blood platelets or clotting factors are missing or not working right. A bleeding disorder should be suspected if the nosebleed can't be stopped. Lots of bleeding from the gums or with minor cuts is also a clue. Bleeding disorders are a rare cause of frequent nosebleeds. Taking blood thinners has the same effect.

Gently squeeze the soft parts of the lower nose together. Press them against the center wall (septum) for 10 minutes. This puts constant pressure on the bleeding point.
Use the thumb and index finger in a pinching manner.
If the bleeding does not stop, move your point of pressure.
Sit up or lean forward and breathe through the mouth during this procedure.
If the bleeding starts again, use the same technique again.
It may help to place a cold pack on the upper part of the nose.
You may swallow some blood if your nose is bleeding a lot. Do not be alarmed if you get sick and you see some blood in the vomit.
Once the bleeding has stopped, avoid blowing or picking your nose.

If pressure alone fails, use a piece of gauze. Wet it with a few drops of water. Another option is to put a little petroleum jelly (such as Vaseline) on the gauze.
Insert the wet gauze into the side that is bleeding. Press again for 10 minutes. Reason it works: the gauze puts more pressure on the bleeding spot.
If you don't have gauze, use a piece of paper towel.
Repeat the process of gently squeezing the lower soft parts of the nose. Do this for 10 minutes.

If the air in your home is dry, use a humidifier to keep the nose from drying out.
For nose blowing, blow gently.
Avoid picking the nose.
Do not use aspirin and ibuprofen. Reason: increases bleeding tendency.
Bleeding areas in the front of the nose sometimes develop a scab. It may heal slowly and re-bleed. Apply a small amount of petroleum jelly (Vaseline) to the spot. Repeat twice a day. Do not use for more than 1 week.
