I got itchness right in the middle of my chest, which makes me cough especially when I talk. The first I got it was in my early 20's. And now I'm 37. It recurred occassionally (Roughly once every 2~5 years) It would last a month or so each time it recurs. The recurrences seemed to be trigger by cold air or surroundings. I wonder what it is and whether it's possible to completely get rid of it.
