As per your query you have symptoms of cold, acid reflux and chronic cough which points towards Gastro-esophageal reflux disease also known as acid reflux in which which acid from stomach enters into food pipe and throat leading to irritation and inflammation which causes heart burn as well as tickling and irritation in throat. You should take combination of proton pump inhibitors such as Omeprazole or Pantoprazole along with antacids such as Calcium carbonate. Coughing is due to throat irritation.
