Hello! I would like to know what is the reason behind severe cough at very rare times? It happens before sleep, maybe during sleep and have sneezing problems once I wake up. Once I consulted a doc after being in bangalore, he told me it's allergic Bronchitis and I should stay away from the area. I took puff for few months and then thought I would get addicted, so I stopped. Then it got high in between and I used this nose drop " TABUNEX" and it worked. But then it's for the moment or day and later again it happens. But it reduced alot. Again now, I find it happening but not too much like before. Coughs and sneeze, how do I reduce them? Hope someone could help me out.
