for the past couple of days, and every once in a while i'll get nosebleeds, for no reason at all. is this a side effect of a medicine? or just an example of the screwed up cf sinuses? most of the time i'm able to get them stopped pretty quickly but every once in a while it'll make a huge mess. it seems to happen only at night or when i first get up in the morning, i'll wake up with them - and my bed soaked, i have to keep a matress protector on it so i don't ruin it with blood. or they'll just start at random. am i just special and others don't get this or is this somehow cf related?
