I had a nose bleed this morning upon waking that lasted for one hour. Lots of thick clots and several inches in length. How to stop them before an hours time? I applied pressure and kept checking to see if it had stopped when the clots would come out. 2 questions: how to stop them and should I be concerned about this being a symptom of another health issue? I am 69 years old, female. I do get nose bleeds often in the morning upon waking, but they usually stop quickly and I attributed them to being dry from my sleep machine.
