I had recurrent sore throat from 2 yrs. Sometimes I can locate a small swelling around the side of my neck at the level of thyroid cartilage.
My endoscopy , X-RAY report shows everything to be normal.
But I have cough also, sometimes dry. And small amounts of sputum is produced mainly during morning time.
And whenever I inhale dusty air,, sputum becomes round shaped and black.
Plz help with the diagnosis
