Possibly: A severe upper respiratory infection, sinus infection, or tonsillitis episode may cause so much inflammation that minor bleeding occurs (blood in sinus secretions or in phlegm from the throat). If the bleeding fails to resolve with the acute illness, you should be evaluated to be sure there is nothing else going on.
