Hi, good afternoon. It started off as a light cough and developed into what i believe a deep chest cold, which I have had since the 24th. Yesterday I thought I was getting better, but today it seems I maybe worse. Here are symtpoms: no fever; no sore throat; no achy sinus; stuffy nose, but can blow, light to mid coughing with some mucus; lackadaisical and sleepy, difficulty breathing. I ve been taking Zirtek daily and in the evening Theraflu. What can I do to get rid of this? Is it possible I could have a walking pneumonia or bronchitis?
