hello Doc,I'm Indu ,27yrs old. Last month I got heavy cough n cold but no running nose.I took BENADRYL cough syrup which gave me relief from coughing without throwing any sputum but i used to cough so hard that my entire front n back chest use to pain very badly and i cant even move myself during sleep or when I lying down. In the morning also i used to have same sever pain before getting up but after getting up that pain was no more after 30mins. This thing I m facing now also......n i always feel that my chest area is packed with something very tight.
