I have an annoying non-productive tickly cough at the moment (along with blocked sinuses), I cant seem to soothe it or get rid of it, and coughing only stops it tickling, once I stop coughing, its back again! Similarly, taking in a big breath of air seems to soothe it for a second or two. My chest and throat are now sore from all this coughing! If I take a good few puffs of old blue, it seems to release something which allows me to cough something up thus getting rid of the tickle. Anyone had this before??
