Bleeding from the roof of my mouth.. when I wake up in the morning I have the need to spit and when I spit it's blood. It's coming from the roof of my mouth.( not every morning ) Not from my lungs or my teeth. I've noticed that my tongue seems to pull a vacuum on my roof of my mouth . I am slightly anxious person. I can't seem to stop that process of pulling on the roof of my mouth with my tongue. after I wake up and get about my day it goes away. But if I get slightly anxious at times it may also happen again. What do I need to do.? I don't want to go or anxiety meds or anything like that
