I developed a cough a month ago after a full month of nonstop activities along with almost a full month of living on 3-8 hours of sleep. It was quite awful at first, as I could hardly sleep and the only way I could was by drinking antihistamines. My spitum was green. I had a round of antibiotics along with 3x daily nebulization of salbutamol. It did cease, but unfortunately I caught a cold on the last day of the antibiotics. The cold went away, but the cough still stayed. My spitum is clear, as well as my xray. No fever, just a persistent cough. If I enter a dusty room, it acts up. If I'm in front of an airconditioner (like if I'm in a car) it acts up. I just want it to go away. I'm not taking anything right now for it. What can I do about it and what is wrong with me ?
