I am 45 year old male. I have quit smoking 15 days ago after smoking for 30 years. For past 8 days after having a sore throat , the phlegm that is coming out, specially in the morning or an afternoon nap is totally red in color with blood. The GP said I had a sinus infection and gave a course of azithromycin on 8-th April. This did not stop the blood in the phlegm and in the GP s suggestion I consulted an ENT specialist . He has now given a course of ciprofloxacin since yesterday April 13. But the blood has not stopped in the phlegm. At times it is totally red, at times with about 80% blood and at times it does not have any blood in it. I can feel there is an infection in the upper throat and typically can guess whether there will be blood in the phlegm, with the intensity of the burning sensation in the infected area. The ENT specialist said he will see me only after 14 days, if the blood does not stop, and has ruled out cancer or tuberculosis . But the blood in the phlegm is really bothering me, specially when it is happening any time of the day, not just the morning. Please advise.
