Hello, I read your query and from what you described it appears that you most likely have bronchial Asthma although I need more information about your cough, it s timing, what aggravates it and what relieves it . Yes it can prove detrimental to your health if not taken care off in time . Ir can decrease your oxygen saturation overtime and increase your effort of breathing. I suggest you go to a nearby clinic and have yourself assessed. You might be prescribed bronchodilators both nebulization and inhaler. In the meantime try 1-steam inhalation 2-Avoid Smoking,dust , strong odors. 3- Avoid cold air 4- Try using a humidifier if you can. 5-Avoid cough suppressants as they will only aggravate your problem. Hope that solves your query.Goodluck.
