Respected Sir, I am suffering from cough since 2 to 3 years. I was under treatment of a local physician but when there is no more relief I went to CMC vellore and was under treatment of Dr. Shakti Kumar Bal, DNB, Asst.prof - Dept. Of Pulmonary Medicine, CMC Vellore. While staying at Vellore I had no problem, but at the returning when I was At Bankura, Westbengal Railway Station then again the cough started, so after return at my home I visited a local physician He gave me some antibiotics and a Cough Syrup Trump-D. But it not work. Whenever I come in contact with cold air the cough started. So I consult the CMC Vellore doctor and he advice me to take MDI Seroflo 125 mch 2 puffs twice daily via spacer MDI Asthalin 100 mcg 2 puffs as and when there is cough in between the doses of Seroflo 125 mcg for three weeks. I am started the Asthalin 100 mcg 2 puffs daily from 01-01-2017 along with when there is cough in between the doses of Seroflo 125 mcg. But still whenever I come in contact with cold air the cough started. One more thing I want to mention that I am working in DAV School, Koyla Nagar as a Lab attd. At Chemistry Lab. One while the Practical was conducting for Std. XII students I have Inhaled Sulphuric Acid and Then Ammonium Hydroxide. After Two or Three days Itching in my throat was started. Please help me to overcome this cough. Thanking you.
