I Had Developed A Cough Due To A Lapband. The

i had developed a cough due to a lapband. the lapband was removed on Dec. 20th with no issues except my cough seemed to have gotten worst. my doctor gave me an inhaler the other day and told me to see if it improves the cough. I have been walking everyday and was doing fine until today. I became short of breath and it took a while for my chest to stop heaving. I do not have high blood pressure or anything else. Is this something to worry about?
