Psychological cough

I've had this on and off cough for years now, and I wonder if it is just psychological? It's usually in the morning and if I cough once I will then feel compelled to keep coughing for hours. Each additional cough will continue the process.

If I resist the cough, I will not begin this process. Is it psychological?
