Ive had this problem for a few years now. The cough is so bad i nearly throw up and can hardly get my breath. Ive had the Mannitol test and it showed a decrease of about 7%. So negative for EIA. I had another tredmill test for EIA but that also came up negative. BUT i still get the horrible cough. It seems to me i need to be tested after a time trial or just a short hill climb as these seem to trigger it(so anything that is really topend stuff). Ive tried beclomethasone combined with salbutamol but this didnt help. Ive also tried Oxis turbohaler and that didnt work either. They suspected reflux was maybe a cause but the drugs dont seem to help either. Im at a loss with it. Maybe its just one of those things i have to put up with?
By the way, this happens in summer and winter. Also cough up mucus and can last for hrs after and sometimes the next day.
Also the interesting thing is that i have a peak flow meter at home and have used it several times after intense sessions/races. One time i did it after a 12.5 mile TT. Straight after the TT i had a bad coughing episode and took salbutamol to relieve. Drove home and approx 30min after the race i blew into the peak flow and took the best of 3 results. 620 was after the race. Before I did the race it was 790.
I think my EIA (if thats what it is) takes a serious amount of aggrivation before it flares up that it doesnt show on the tredmill etc.I also know 'by feel' that those tests were in no way simalr to the efforts i put in when i race.
I wonder if this is why the asthma drugs they have given me dont work.

Happy New Year to you all!!
