question: Hello doctor, I feel something stuck in my throat and constant clearing of mucus for a month now. But, there is no pain while swallowing. I had Azithral 500 mg for five days, but it did not work. Since five days, I have been taking Pantodac 40 mg. It has cured the feeling of something stuck in throat and mucus is still coming, but has reduced a little. During the daytime, the mucus is white and as soon as I wake up it is light green in color. I am completely anxious and stressed for the past five weeks after the incident of unprotected sex. Is this related to HIV? I am getting scared of this. Please help.
