I am a 34yr old male, i was told i had G.E.R.D, a hiatil hernia and i have fructose malabsorbtion. I have blood in my saliva in the morning and night, for around 4yrs, i also get it when i sing loudly or shout, and when i suck on something, it automaticly fills my mouth with blood. It usually starts light brown then becomes bright red and is almost pure blood if i continue spitting or sucking. I have had endoscopys and seen an E.N.T doctor, and i have also seen a dentist all with no explanation. Can you please give me some dirrection,who to see next? Thank you. Steve.
