Have sore throat, cough with blood, had cold which subsided. Taking vitamins, rest. Serious?
my boyfriend has had a sore throat for 3 weeks now. it started out as a cold, but his other symptoms went away after a week. Now he's been coughing up a little blood. he's been eating really healthy, taking his vitamins and getting plenty of rest. is it most likely just part of his cold that hasnt gone away yet, or would it be the start of something more serious? he hasnt gone to see a doctor.
