I Have A Dry Cough. Went To The Doctor They

I have a dry cough. Went to the doctor they say lungs are wide open. Put me on antibiotics, steroids, and an inhaler. No fever, no runny nose ,no watery eyes, no sore throat. I have had the cough for 11 days. It began on March 22nd It started when I was on vacation in Savannah. They was very heavy pollen but I have never ever had any allergies. I live in Buffalo. My question is on March 10th I had a heart ablation done for Afib. After the procedure they increased my flecainide to 150 mg twice a day and kept me on atenolol 25 mg once a day and for the first ever put me on eliquis 5mg 2x a day. Could this be the problem?
