I had a dry cough for month at night and I consulted the doctor and he said: no issues in particular but prescribed montek lc with salt water gargle at night. And it did work well. But when I stopped medicine after a week. 2 days later when I'm exposed to dust. I had the same symptom. But this time it's more throat irritation and occasional wheezing (only at the peak of throat irritation) but no dry cough instead I cough because of throat irritation. I have no breathing issues. What is this symptoms of?
