Hi my name is dean I'm 22 and for as long as I can remember I would always have random nose bleeds and in middle school threw high school I would always have too take deep breaths and the only way too to get the deep breath I need is too stop what I'm doing and make myself yawn do get the air it feels like I need and a lot of times I have too do it every 5-15 minutes. Its more consistant when I lay down. Usually every 3 minutes I have too sit up and make myself yawn to once again get the air I need. This has been going on for years. I am not allergic too anything and I'm fit.. I weigh 150 pounds and eat fruits and all the normal food and junk food. I do not smoke or do drugs of any kind. I drink acationally But nothing serious. I'm becoming very concerned about this problem and was reading it could also be heart failure. When I was a kid I remember being diagnosed with a heart murmur.. Could this possibly heart failure..? PLEASE HELP ME WITH AN ANSWER.!!!!!
