Itching Sensation In The Rib Cage While Coughing, Shortness Of Breath. Asthma?

I am feeling an itchy sensation when i cough. It feels really good when i cough, almost as if I am itching the inside of my rib cage. I think it may be assoicated with asthma? I was diagnosed a few years ago but they were different symptoms more like shortness of breath. The symptoms went away and now it appears the symptoms have changed. Do my new symptoms sound like a form of asthma or is this non-related? I feel like when i breath in, almost like my wall is closing and there is not enough air getting through, at the same time, i feel like my rib is itching on the left side and when i cough, it feels great but after i cough it burns as well! Help please
