I used to have an occasional nosebleed, maybe once a month or less. Usually when I was in bed.

I mentioned it, because I had one that morning, to the doctor at the ENT clinic I had gone to for a sinus issue.

He said he could take care of that and cauterized my nose.

I started having nosebleeds once or twice a day. When it was still happening two weeks later, I called the clinic who suggested I go to the ED. Not back to them (they are part of the hospital).

I went to my doctor instead, who had a look. They eventually stopped, but I still get the odd one.
