The most common reasons for nose bleeds are (1) trauma (for example, by picking or rubbing your nose) and (2) excessive dryness (usually due to dry weather), which may chap the nasal tissues.
Tumors of the nasal cavity and tumors of the sinuses can also cause nose bleeds. Danger signs that suggest the possibility of tumor include:
Nose bleeds which recur over the course of a few months
Nose bleeds associated with any of the following:
loose teeth, numb facial skin, a change in vision, a change in occlusion (the way your teeth meet), or any deformity of the facial contour
If any of these symptoms are present, bring this to your doctor's attention at once!
If a doctor has determined that your nose bleeds are due to one of the common benign reasons (trauma or dry weather), you can help prevent further nose bleeds by observing the following precautions:
Needless to say, DON'T PICK YOUR BLOODY NOSE! (Pun intended.)
Do not lift any heavy objects (more than 20 pounds); do not strain or bend over for long periods. Do not strain at bowel movements; take a fiber supplement or a laxative, if necessary.
Do not forcefully blow your nose.
Sneeze with your mouth open (this will reduce the force of the sneeze).
Keep your nose moist. A salt water solution (Ocean, Ayr or NaSal are easily obtainable brands in the USA) may be sprayed in each nostril every 2 to 3 hours, or as often as necessary. Ayr Gel is an excellent product as well.
[Some products available without prescription are, as of this writing (2005), a bit too new to evaluate. NasalCease and QR powder are two examples. I'm still waiting to hear what my patients think of these products.]
Consider buying a humidifier for your bedroom, especially if your house is very dry. Use it at night. For added moisture, you could spray with nasal saline or use Ayr Gel.
If you develop a nose bleed, rest quietly on a couch while applying firm, gentle pressure to your nose. Do this by pinching your nose between your thumb and forefinger. Hold pressure for 5 to 7 minutes. If the bleeding continues, gently blow the clots from your nose, then spray each nostril with Afrin (generic: oxymetazoline) or Neosynephrine (generic: phenylephrine). (This assumes your doctor has cleared you to use these medications.) Hold pressure again for 5 to 7 minutes. If necessary, you may repeat the spray 15 minutes after the first spray. If the bleeding continues, seek medical attention at once.
