Nose bleeds in the morning

I've dealt with nose bleeds most of my life.  The annoying thing is that I'll have 3 in a week, and then none for 6 months.  I'm supposed to be nasal rinsing and applying vasaline as preventive care.  However, I get lazy when its been six months between.

As such, I was caught completely off guard when my nose started bleeding on the plane on Friday.  Fortunately, at that the captain had turned off the seatbelt sign; I could move about the cabin to the bathroom in a rapid fashion. 

I was also caught off guard when my nose started bleeding on the way to work this morning.  I was about 10 minutes into my 30 minute drive when I felt that drip, drip, drip... Not a great way to start a Monday morning.

But I realized that I've had a touch of seasonal allergies this past couple of weeks.  And last fall I had some seasonal allergy sypmtpons when I had 3 nose bleeds in a week.  So!  I may have tracked down one root cause of these things.  Score one on my side!
