What Causes Severe Cough Post An Exposure To Burnt Plastic Fumes?

A week ago a plastic spatula melted in my dishwasher. It filled the whole house with a burnt plastic odor and I had to let the house air out all night. That said, I was exposed to this during the airing out, and also when I opened the dishwasher to investigate. Ever since that night, basically for the last week, I often auto-reflex cough when exhaling because of an irritation in my throat. It s a tickling/burning irritation that automatically makes me cough when exhaling about once every 5-10 minutes or so throughout the day. Should I go see a doctor about this? If so, what would the examination be like? Or should I just give this more time to see if it goes away? Thanks.
