Hi and thank you so much for this query. I am so sorry to hear about this throat problem that your husband has. It would be very unlikely that repeated testing that went as far as investigating for cancer would have missed a fungal infection in the throat. I understand you are desperate to get a diagnosis but accepting a wrong diagnosis is even worse than not admitting that a diagnosis has not been reached for your husband. My advice is simply not to be tricked in believing what this natural doctor said and continue searching for possible answers to why your husband has this condition or accepting that there is no underlying pathological cause to his symptoms. Constant urge to clean the throat could be cause by acid reflux disease and postnasal drip. I will suggest that you get this investigated into as chronic cough and not accept wrong diagnostic impression. I hope this addresses your query fully and provides enough information for you to act on. Feel free to ask for any clarification or more information if needed and I will gladly respond to.Thanks for using our services and I wish your husband well. Dr. Ditah, MD.
