As it says in the title, this is the 3rd nosebleed I've had in the past 3 days. I'm not a chronic nosebleeder so this is concerning to me (the last time prior to these episodes I've had a nosebleed was in December. ) I made the mistake of consulting Dr Google and now I fear that I have leukemia. It should be noted that I do typically have allergies act up at this time of year but it has never historically involved my nose bleeding. These episodes usually occur at a random point in the day, once, and last 30-45 seconds then dont occur again for the rest of the day. I'm just very concerned.
