Have had cough for 2 months, and since Christmas, my ears have felt plugged. Have had 3 courses of antibiotics and still no better. Cough doesnt feel chesty and doc says chest is clear, but I am worried as I suffered from non-smokers lung cancer 6 years ago and had half my left lung removed. Doc also says ears are clear when he looks through with his little microscope thing. I am seriously worn out! Has anyone had similar?
