I have a severe cough that sometimes drives me crazy: it is like a very irritating tickle and hard cough is only thing I can do; sometimes my neck will itch, and have runny nose; I use (sugarless) cough drops, but sometimes even with them I continue to need to cough. It comes in clumps because yesterday was about all day thing, then today not at all with no cough at all; I have been on the drug Losartan, but only take with evening meal, so can it have anything to do with this recently developing persistent cough: I have just been diagnosed by cardiologist that a virus has damaged my left ventricle and also on drug Carvedilol 2 x day
