I was having running nose followed by cough. But after one day running nose was subsidized and coughing started and it was wet cough. So I took Bro Zedex cough syrup to gert relief from cough. But after taking this syrup my chest became tight and phlegm were not coming out. I felt breathlessness. My throat was seemed to be blocked with mucus. While coughing I felt pain in my body as it was giving lot of pressure to cough up phlegm. Though I do not have history of asthma but I felt my breath is becoming rapid and whenever I take deep breath I get a itching feeling in my throat and it leads to coughing. Please let me if I am suffering from chest infection.
