2 months ago, I was suffering from cold and dry cough. It was not troublesome so I took dry cough syrup and the cough seemed to ease off a little bit. But I used to have cold and stuffed / blocked nose every morning. The cold never stopped but it was not very troublesome so I did not bother. Last month, I started having difficulty breathing while sleeping in the night. I began taking dry cough syrup tusq dx syrup and the shortness of breath didn't trouble as much. And now since 3 days i'm having difficulty breathing several times round the day. ** in summary:** cold and dry cough since 2+ months. The cough (phlem) has become very thick and jelly like. I'm going to visit a doctor too. I just want to know if this is normal or could be something very dangerous. Also, what would be your advise?
