I've been tasting and feeling blood going down my throat from my nose. It's not all the time and it's not on a regular basis, it just happens all of a sudden. I already went to see an ENT doctor and he gave me antibiotics and a nasal spray to take for about a month, which did kind of help but did not stop it completely. (He says I have sinusitis) I'm worried since I saw an episode on The Doctors that said that sometimes it could be a sign of a brain tumor. Someone please help. I also have tinnitus and I've been diagnosed with GERD. Don't know if that could be related.
