I am guessing that I have this condition, after seeing many specialists in South Africa they can find no positive reason for my persistant agressive coughing. Basically every time I inhale quickly as when laughing or shouting, when bending forward or sitting in a low seat, any exercise like walking up stairs. I used to be very active & sporty but now am always tired and consequently have become overweight. I had scans where they found a number of small nodules in my lungs when I had an operation to have one removed it was diagnosed as non malignant but no other comment. I have a mild reflux condition and slightly abnormal gastric action where food passes through my asophegous into the duodenum, which can cause coughing but not to the extent that I suffer.
