I have problem in my nose their is balgam in my nose every time it is almost 3 years I am facing this. And the balgam is of green colour it is hard. Some times it blocks my nose I can't breath properly. I consulted doctor 2 year back. Their was no sinus and he told it is allergies when he gave medicines their was pimples on my forehead. So I left medicines after eating a month. Tell me from which disease I am suffering from? And what is its permanent solution?
