Hi I am 56y female. I have recently had quite a severe cough and chest infection, it has subsided a little in the past week or so, but whenever I cough, or should I say a few seconds after I cough, I get this terrible taste in my mouth, it tastes like what old flower water in vases smells like, thats the only way I can describe it, and believe me that aint my kind of drink! What could it be, and how could I get rid if it?
