My sinus muscus has become blood streaked, early morning it is dark red old blood but throughout the day when my muscus drains down my throat it is pinker or brighter looking, I also have dizziness with position changes. I have had repeated sinus infections in years past but for the past couple of years I have been able to treat the symptoms, keeping my sinus from becoming plugged. I have had thick foul smelling drainage also but do saline flushes at the time. Is this normal, could I have seeping spinal fluid?
