I've had a cold about two months ago, and after a cold was gone I started feeling throat tightness and coughing, also tickle in throat, then I had another cold about a month ago and it went away too, and i am still feeling throat tightness, tickle and coughing. Sometimes when I start talking my throat gets tickleish and I just have to cough. Also when I touch my lower neck it makes me want to cough and get this weird feeling inside the throat.
