Hello. Am 25 year old, from 2 weeks I was having cough and cold, on first day of cough got fever but after taking calpol its cured and after days with some tablets cold also cleared but my cough still remained same. I have took the cough syrup "deletus-p" and tried deletus-d also now am taking ventryl-d. But am not finding better. Nowadays am getting slightly pain pain inside the chest and in throat. While breathing the sound is coming. Please suggest me. However days are passing bcz of this cough am getting scared.
