Re: random nose bleeds
Like kitkat77 said, the weak blood vessel is in your left nostril, so that's the one that bleeds. It is not uncommon for extreme dryness or forceful blowing of the nose to cause this. If it is only once every three weeks or so, I wouldn't worry too much. A nosebleed can come from the front of the nose interior (in which case, the vaseline may help with the dryness), or deep within. If it becomes a daily problem, you can get a doctor to cauterize the problem blood vessel.j.
