I woke up with a nosebleed and thick blood running down my throat, after 15 min. I got it to stop. Half hour later while standing nosebleed returned. I don't get nosebleeds, my house is not dry, I did not have a stuffy nose or cold...now I feel shaky, nausua, and although the nose has stopped bleeding...it feels like presser in the nose and I worry it will start bleeding again. I checked my blood pressure first nosebleed 111/79...now blood pressure is 143/80 . I am on blood pressure meds and aspirian. I am 53 yrs. old...do you think something is wrong?
