Ok so I get nose bleeds all the time sometimes they just come out of no where...im pretty healthy and really active... Does anyone no why?
It could be the air, it will dry out your nose on the inside and it will get all chapped and cracked in there and bleed, it also could be elevational changes, have you moved lately? Try a humidifyer in your room, because chances are the way the weather has been lately this summer, you could be very dry up in there, so try a humidifyer in your room for a while see what happens.
Do you drink aspirin for headaches or body aches ever?
That causes your blood to thin and could be another possible explanation for constant nose bleeds.
