Hi there, When I get sick (I currently have a virus, runny nose, post nasal drip, mucous and coughing). When I cough I taste blood in my throat. No blood comes up, just clear mucous, but it is a very strong taste of blood. I don t taste it when I clear my throat, only when I cough. This starts right away, first day of the cough. I have had this exact symptom where I taste blood after coughing, for the last 5 years approximately. No blood has come up. Should I be worried?
