Hi..Sir I Have Been Smoking Past Three Years . But

Hi..Sir I have been smoking past three years . But last few days I have been coughing up brown phlegm . But today along with the brown phlegm there was a red spot in it. I had a cold and cough three days earlier and I am having a sore throat right now.
According to my past medical records I have already suffered from tuberclosis.
Is it a worrying situation at this moment.
