you need to worry about the blood comming from the lungs if you are smoker, older than 40-years, and have previous cancers, or your are having blood comming with the urine, or you are having skin rash, or history of asthma.
hope this will help you.
Let me add that the winter time is notorious for causing nose bleeds. Its not so much the plummeting temperatures that cause them, but the fact that the air is very dry. A dry environment can make the lining in your nose thinner and more vulnerable to minor irritations.
Some things to do that can lessen the occurance:
- Drinking more water.
- Using a salt-based nasal spray as frequently as necessary.
- Gently applying a small amount of petroleum jelly to the lining of your nose.
- Using a home humidifier.
- Avoiding regular use of aspirin and other anti-inflammatory medications. They diminish the blood's ability to clot.
Goodluck, hope this helps...
