Presistant Throat Clearing and Coughing with rare occurances of Blood
My wife has been coughing about 2-5 times a day with constant throat clearing for over a year or two. Once in a blue there will be bright red in her sputum. I took her to a very well known ENT specialist in our area. He used an endoscope to check through her nose and throat and found nothing. We also had chest X-Rays done and also nothing.
She does not smoke at all and has not had a drink in two years. Even when she did drink it would only be an occasional wine cooler or a glass of white wine. She is an African-American female in her early 30's. Im very worried and i would give anything for some clarity.
