A Few Days Ago, I Inhaled Some Crumbs While Eating

A few days ago, I inhaled some crumbs while eating food. I am severely asthmatic and don't have a very productive cough. Ever since I inhaled the crumbs, I have had a 'wet' (bringing up lots of phlegm) cough that worsens every day and is worse when I lay down. I am wondering if this could lead to aspiration pneumonia and if I should seek medical help.
