Hey everyone, first off I do not have c19. I have Had a slight cough ever since my aortic OnX valve replacement with a single bypass surgery on Jan 23. My cardiologist doesn’t understand why as well. He thinks it’s because my bronchiole tubes are irritated from being intubated. He prescribed me Benzonatate 100mg pills to take three times a day. They work about 3 to 4 hours out of the eight that They are supposed to. I also have “Active asthma “ I’m more prone to problems during the summer when mold high humidity and particulates are stagnant in the air. My question is have any of you experienced a cough that has gone on for almost 3 months. I am going to go see my asthma and allergist hopefully today and see what he thinks. Any information would be helpful. Thanks again for all the support.
