Whooping Cough, Need To Take Shallow Breaths In Order Not

Whooping cough, need to take shallow breaths in order not to cough. Once I start coughing I can't stop until I get up a thick metallic taking saliva/mucus. It is worse at night and laying down and can't sleep. Cheeks feel hot but hands are very cold. Last, is horrible headache and pressure behind ears. I also just returned from international travel.
