I also have the cough and it does not subside
for several days after exposure. The
asthma specialist suggested doing the Provocholine Challenge test, but I felt as though this might be dangerous for me due to reactions to the medications utilized in the procedure and declined. Consequently, Dr. bumped up my Advair to 250/50 and then to 500/50, which I am currently taking along with Singulair, Claritin and Naxonex.
