Hi Jennifer,
I come from a family who all had trouble with nosebleeds including myself. I don't have them anymore, but it seems my son inherited that from me because it does run in my family. We bought a home humidfier for our house to keep the humidity up in house and that has helped tremendously, although my son doesn't live with us anymore (23). He still has problems with bloody noses especially since he doesn't have one in his new house yet. We used to apply pressure (pinched it or put a clothes pin on it) on the nose and keep an icepack on that area just above where we pinched it and also on the back of the neck as well. Perhaps he will outgrow it as we all did; you can also buy that saline solution which also adds moisture for the nostrils as well. My nosebleeds used to last for a good 10-20 minutes over the sink and which added to my anemia problems when I was young, but I don't have them anymore. I am waiting to see if my son will outgrow them as well. You can always check with your doctor or also check some of the health food stores for herbal remedies.
