Blood in mucus
Hello Doctors, Yesterday night I had a very uncomfortable sleep. My entire body was aching and my throat was paining when I swallowed saliva. Today morning I sneezed and I could see small amount of blood in mucus. I've been having cold from quite some time now. I do not have any cough or fever or vomiting. I have a stiff neck and slight headache too. What could be the reason for this?
