Rehan Adil [/INST] HelloWelcome to Ask a Doctor Service I have reviewed your query and here is my advice. The findings are not suggestive of any disease of illness, and what ever the cough symptom he has that could be due to some allergic condition or may be nonspecific if this is the allergic condition then it is self limiting and no need to worry about this Mild TR has nothing to do with the symptoms he has, you can discuss this with his doctor Hope I have answered your query, let me know for further assistance. </s>
