Occasional blood in the sputum
Good day, I have had slight traces of blood in my phlegm for a few days now (specifically since Monday morning), especially when I (please excuse the expression) cough up the mucus. Yesterday I visited the doctor and was sent for a lung X-ray, which showed that my lungs are completely fine, which is a relief. At the beginning of the year, my throat was also examined and nothing unusual was found, just a lot of mucus. I almost have the urge to produce mucus to see if there is blood in it or not (only a few times). Now my question is, what else could be causing this? Today I also have slight sore throat and a scratchy feeling in my throat. Could it be that constantly producing mucus is irritating the mucous membranes? Oh, I should also mention that I unfortunately smoke. I am very scared and would appreciate your response. Thank you very much.
