How Can Cough Be Treated While Suffering From High BP?

For the past several days I have had a nagging cough (with no other cold-type symptoms, no fever), accompanied by an off-and-on difficulty in catching my breath when I take a deep breath. I have no other symptoms or pain. I don t feel overly tired, no more than usual that is, after doing 4 loads of laundry today & other housework. I do have a long history of high blood pressure, cardiac arrhythmia & high cholesterol, which are all under control with medications. Should I just continue taking the cough medicine or see my cardiologist? Thank You.
