Persistent blood in saliva almost every morning

[mbryant]

I know this thread is old and I'm at work so I was only able to skim some responses. I've been spitting blood off and on in the mornings for about 3 or 4 weeks now. I spit in the sink when I wake up and there's blood. Sometimes spitting a couple of times clears it up and I'm good. Others (like today) I'll have to snort through my nose and hack a bit to get it. I'm sure that does nothing but cause more problems though.

Of course googling says I have lung cancer so I'm freaking out just a little bit.

I have post nasal drip , with blood tinged in saliva it's not much blood really , but it still worries me , because it started like 3 months ago and still happening everyday , the blood in spit recently started last week. 3 months ago I went to the ER because I had back pain in my shoulder blade that till this day still hasn't gone away , it tends to come and go throughout the day. That day I got x-rays done , blood test , urine test , ekg and everything came back fine. So I don't really know what's going on , I'm 20 yrs old so this is strange to me.

I'm getting this at the moment, first thing in the morning.
I suffer with my sinuses which can make me cough a little during the night.
I'm wondering where this blood comes from because I check my teeth and gums and can find no trace.
