Hi, and thank you. I am a 19 year old male. I live in Florida near the Gulf and thereis a heavy concentration of red tide. I have been here all my life. This past year I would cough a few times a day. It sounded somethimes dry, but mostly as if I had a cold. On Feb 2,2013,I stared feeling a tightness in my chest.
