I was diagnosed with Congestive Heart Failure in 2016. Have not felt well since then. I have had a persistent cough since July 2017. Had pneumonia in September 2017 and the flu in January. Still coughing. Three chest xrays have been clear. For a long time it was a dry cough, now I am spitting up phlem. It is sometimes thick but always white. I tested negative for allergies, negative for sinus polyps. Cough syrup does not work. I cough so hard I pee on myself. I have pooped on myself also. This is getting to be hard to deal with. Can you please help me?
