I have the following symptoms, & was wondering what it might be? And also, what type of doctor you would recommend for a visit to get a diagnosis? I have trouble breathing..... the only relief is coughing, & I cough up clear mucus. My chest feels heavy almost all the time, & I am also experiencing shortness of breath. In addition, my face becomes red on my forehead , the left side of my face, & left side of my neck, & my nose has red spots. I feel like this throughout the day; but it seems to be worse after eating.
